In 1973 REMBE was founded by Bernhard Penno.

In addition to the core business of bursting discs for

the chemical and process industries we started business

in the field of measurement technology in 1978.

Since 1988 REMBE has continuously increased its export

activities. Today we are represented globally in more

than 70 countries, and have dedicated REMBE facilities

in the key industrial areas. Still a family owned and

privately run business REMBE is able to provide fast,

efficient and reliable solutions.

The Company

REMBE GMBH SAFETY + CONTROL is an independent,

privately run medium-sized family business with the

advantage of short decision-making paths and a high

level of flexibility. Its extraordinary innovative strength

is reflected in numerous patents and in its eagerness

to discover, research and invest.

Product range

REMBE’s core competences include the protection

of industrial plants against vacuum and excessive

pressure operating conditions. Process safety in

industrial production is provided through bursting

discs with various functional principles as well as

with other pressure and breather valves.

Engineering

The product range covers all applications and industries, from

standard products to special high-tech solutions, coupled with

application expertise in all industries throughout the world.

REMBE’s know-how ranges from the lowest to the highest

bursting pressures and includes sensor engineering, software,

standardisation, consultancy, research, development, as well

as prototype testing.

Manufacturing

REMBE manufacturing facilities are located in Brilon, Germany.

Production processes require a minimum of resources, using

state-of-the-art laser machines and high-performance presses.

All standard nominal sizes (DN 15 to DN 1400 / ½" to 56") are

certified under global safety standards and regulations. Each

series that has ever been manufactured can be traced back

to the year 1973, way beyond the average life of any type of

production process plant.

REMBE’s in-house test capabilities offer temperature tests

(from -269 °C to +800 °C, even with high-pressure

applications), explosion tests, the identification of dust

coefficients and tests within pressure ranges of 10 mbarg

to 7,000 barg.

leadtimes. Additionally the REMBE RUSH ORDER SERVICE

provides production and delivery within 24 hours ex works

subject to material availability.

Customers are given specially tailored expert on-site

advice on all issues of process safety, process optimisation

and insurance cover. After viewing a customer’s facilities,

REMBE provides each customer with its own safety scheme.

Legal stipulations can be covered as early as the planning

stage – not just at the approval stage.

Certified conferences

REMBE holds regular professional seminars on

“Optimised Process Safety with Bursting Discs and

Safety Valves”. Well-known speakers comment on a

wide range of safety issues and provide information

on the latest versions of directives and standards

and on the latest technology.

EIC and FPAL, where we work towards improvements in

º7

safety standards while also keeping abreast of the latest

industry standard requirements and developments.

Customer satisfaction

REMBE’s technical support, its solution-focused

customer service and its experience in application

engineering provide customers with security for their

planning and for the operation of their systems. A high

level of reliability in consultancy and the right choice

of products are just as much hallmarks of REMBE’s

engineers as their understanding for a company’s

production processes. Each customer has the same

reliable REMBE relationship wherever they are located.

BT-ODV Triple section bursting

discs are normally applied in

low to medium pressure

applications and have an

operating ratio up to 80% of

the burst rating. The burst

element with its laser cut

breaking points ensures a high

degree of precision and in

combination with the sealing

membrane determines the

burst pressure.

In corrosive media applications,

the burst element is isolated

by the sealing membrane, which

is normally made of FEP/PTFE,

but can also be made of SST

for higher burst ratings.

An integrated vacuum support

enables cyclic pressures from

full vacuum to positive pressure

within the 80% ratio boundary.

BT-ODV Discs are installed in

the IG Bursting disc holder.

Sizes from DN 20 (3/4") fit into

the U-Holder unit while the

ST-ODV disc fits into the

S-Holder unit.

These forward acting

Bursting discs are suitable for

a wide range of low to high

pressures. The triple section

design minimises the risk of

fragmentation, at all pressures,

with its star shaped opening

formation.

To achieve the lowest possible

tolerances, the breaking points

are introduced utilising state- of-

the-art laser production

technology. An integral vacuum

support guarantees full vacuum

resistance irrespective of disc

Size, up to DN 600 (24").

The burst element is down-

stream (venting side) of the

process, away from any corro-

sive media, thereby providing

problem free production

in corrosive media processes.

The operating ratio of the

BT-STAR Disc is 80% of the

burst rating.

In applications below 1 barg the

BT-STAR Disc can be installed

directly between companion

flanges, without a companion

holder.

For medium to high burst

ratings, the entire assembly,

including the sealing mem-

brane is constructed of stain-

less steel. When used with

a flat seat IG-HL Burst disc

holder the assembly provides

absolute leak-tight integrity.

In case of burst pressures

> 1 barg and installation into

disc is mounted in a bursting

disc holder. This combination

ensures safe and optimum

leak tight assembly and

operation of the bursting

REMBE bursting disc holders

generally consist of an inlet

and outlet component. Costly

mounting is not necessary.

The parts are fixed by a pre-

assembly kit and are always

re-usable, unless damaged

or corroded (in which case

material compatibility with

the process should be

investigated).

The standard bursting disc

holder IG with 30° clamping

BT-KUB / BT-KUB-F(L)

This unique reverse acting

bursting disc, incorporating

laser cut buckling pin design

features, represents the most

rugged and versatile bursting

disc available in today’s

technically driven market.

The buckling pin cut profiles

work according to the formula

calculated by Leonard Euler

and enables the lowest

possible tolerances.

The BT-KUB can be used with

any gas, vapour or liquid media

under the harshest of

conditions due to its standard

operating ratio of 98%, the

tightest operating ratio avail-

able in the burst disc industry.

The two layer material design

and range of materials of

construction offer the greatest

flexibility in cost savings while

maintaining total corrosion

resistance. The disc design

comprises of an upstream

sealing membrane with a

smooth unblemished profile

ie; no scorelines, dimples or

indentations. This makes the

BT-KUB the ideal disc for

aseptic and sanitary

applications due to their

being no available dead space

for bacteria or product

accumulation. The material

selection of the sealing


● Easy handling dueto outstanding robustdesign

● Fully torqueindependentinstallation

● Extraordinaryservice life

* Vent area compliant with PED certification, MNFA (ASME Sec. VIII, Div. 1) may vary.

Other sizes on request

membrane should be specified

according to the requirements

of the process (possibly corrosi-

ve) where the disc is being ap-

plied.

Due to the reverse acting com-

pression mode of the disc, it is

also totally immune to back-

pressures and vacuum and is

ideally suited where CIP/SIP

scenarios are used.

Downstream the burst

element with its buckling

pin technology is totally

isolated from the process

and can be confidently

specified in standard

SST irrespective of any

aggressive process

media; dependent upon

no corrosive vapours

being present down-

stream.

The BT-KUB is totally torque

independent when mounted

in the IG-KUB Disc Holder. Its

response pressure performance

(burst rating) is not influenced

by the torque applied. For

pressures below 1.0 barg,

the BT-KUB can be installed

directly between flanges.

BT-KUB-V-Series

With the unique and

innovative generation of

bursting disc BT-KUB-V-Series

for the first time it is possible

to perform the Partial Stroke

Test (PST) on pressure relief

valves (PRV) while in plant

operation conditions, i.e.

“in-situ”. Expensive loss of

production due to downtime

and costly dismantling/

mounting times are reduced

to a minimum. Optimum plant

production is maintained.

The concept of the BT-KUB-

V-Series is both ingenious and

convincing: The bursting disc

is installed upstream of the

pressure relief valve. Apart

from the absolute tight

sealing of the process line,

the pressure relief valve is

now also protected against

the effects of corrosion and

contamination. On site, the

pressure relief valve can be

lift tested for any possible

leakage. The unique back

pressure resistance of the

BT-KUB-V-Series is achieved

by modifying the proven,

double-layer KUB design.

The performance

characteristics and the

flow rate of the pressure

relief valve are not influenced

by the upstream BT-KUB-

V-Series bursting disc.

Conventional single layer

scored bursting discs cannot

meet these requirements.

BT-KUB-G-Series

Providing a unique

option, the BT-KUB-G-Series

reverse acting disc is the

world’s first ever bursting

disc manufactured for the

challenging demands of

geothermal power plant

applications, as the

endurance of a bursting

disc is defined by the

extreme temperature

and constant corrosion

requirements.

Special finishing technology

is used to withstand these

aggressive effects, providing

more than double the

lifetime of the disc when

compared with more

conventional “scored”

bursting discs.

Needless to say this provides

considerable operational cost

savings.


● Cost-savingoperation

● Easy and quickinstallationwithout specialtools

● High operationalsafety

BT-KUB-G-Series before and after having relieved pressure


Bursting disc holders with

integrated heating channels

are specified typically for

applications such as

polymerising media,

reducing the risks of product

accumulation and adhesion to

a minimum. The heating

channels are integrated all

around the holder

The holder is easily and

safely heated with hot

water/vapour or thermal oil.

Holder connections can be

flanged or threaded or other

bespoke customer driven

designs.

Alternatively the same

holder configuration can

be used as a method of

cooling by utilising water

or refrigerant.

IG-KUB

The reverse acting bursting

discs, BT-KUB and BT-IKB

are installed between the

bursting disc holder IG-KUB.

Consisting of two parts; Inlet

(upstream) and Outlet

(downstream) both parts are

joined together by means of

a preassembled retaining

clamp, which is easily dis-

assembled when the bursting

disc needs to be replaced or

inspected. If the disc is

undamaged it can be re-

assembled into the holder,

or a replacement disc is

installed if the existing disc is

damaged or it has actuated

(opened due to pressure).

The reassembled bursting disc

unit will provide guaranteed

totally leak tight seal due to

the high precision metal-to-

metal sealing configuration.

The metal-to-metal sealing of

the holder does not require

any additional gasket.

The IG-KUB Holder is a pre-

cision engineered component

with very tight tolerances in

order to guarantee leak tight

integrity. When inspecting or

changing out bursting discs,

the metal-to-metal sealing

faces should be totally clean

and free from any mechanical

damage or corrosion. If me-

chanically damaged in any

way the bursting disc holder

will need to be replaced.

If corrosionis evident, correct/

alternative material specifi-

cations should be investi-

gated.

IG-KUB-DD-S

For this version, two BT-KUB

bursting discs are connected

in series. Facilities/production

processes which are subject

to extreme conditions, such

as very corrosive, VOC’s or

other highly toxic media, are

equipped with two bursting

discs in series.

They provide considerably

more safety. Both discs can

be rated at the same pressure

and temperature or rated at

different pressures.

Monitoring of the inter-

space between the two discs

via a tell-tale assembly

comprising of a pressure

gauge and excess flow valve

enables signalling of burst

disc actuation as well as

indicating any leakage

caused by possible corrosion.

In case of identical or

different set pressures the

secondary bursting disc

presents additional safety

for the facility/process.

IG-KUB-DD-S double

disc assembly holder

is a preassembled unit

and is normally installed

inside the bolt hole PCD

of companion weld neck

flanges.

are used mainly for low and

medium burst pressures in

many industries. The laser-cut

burst element with its

breaking points provides

precise burst pressures and

the multilayer design

guarantees

an operating ratio up to 80%.

Additionally the integrated

sealing membrane protects

the burst element against

corrosion. Even at lowest

burst pressures < 0.1 barg

BT-ODV bursting discs up to

size DN 1000 (40") can be

manufactured with

full vacuum resistance.

Installation between flanges

At burst pressures up to 1.0

barg (for sizes ≤ DN 150 / 6"

even at higher burst

pressures) bursting disc types

BT-ODU-F and BT-ODV-F are

directly clamped between

welding neck flanges IAW

DIN 2631 or EN 1092-1

type 11 PN6.

Clamping between other

flange types is possible, either

by adjusting the dimensions

of the bursting disc and / or

of the flanges by using

spacer rings or combined with

Dual rated Bursting Disc for Protection against Pressure and Vacuum

BT-ZW-F

The bi-directional acting

bursting disc combines

the proven function of two

bursting discs: on the one

hand that of the forward-

acting triple section bursting

disc ODV and on the other

hand the reverse acting

buckling pin bursting

disc KUB.

Different response pressures

can be achieved. It protects

in one direction against

inadmissible pressure and in

the opposite direction against

inadmissible vacuum. The

bursting discs takes on the

function of two bursting discs

in one single assembly.

The BT-ZW-F bursting disc

offers the benefits of freedom

from maintenance, reliability

and robustness, even at

lowest response pressure. The

ZW opens fragmentation-free

in both directions and is suit-

able for liquids and gases.

Unpressurised tanks with

low stress capability are

typical applications.

In the vacuum direction, the

response pressure is fixed

by the forward-acting burst

element with its breaking

points. Protection in the

pressure direction is provided

according to the KUB

buckling-pin principle.

The sealing function is

provided by a PTFE or

FEP membrane.

The bursting disc is mounted

directly between flanges or

angular rings. A separate

bursting disc holder is not

required. By means of the

SNR inductive signalling unit

the bursting disc can be

monitored in both directions

at the same time.

SK

The SK is an integrated

signalling device which is

directly connected on top

of the bursting disc

(downstream). Upon

actuation of the bursting disc

the normally closed circuit is

interrupted.

The SK can be used on triple

section bursting discs as well

as on reverse acting KUB

bursting discs larger than

DN 80 (3").

The SK signalling unit is

intrinsically safe and can be

used in explosion hazardous

areas ie Zones 0 and 20.

FOS

The FOS fibre optic bursting

membrane monitors leakages

and the response of bursting

discs in high corrosive

atmospheres and hazardous

areas, and/or whenever

electrical connection is not

permitted or possible at the

point of installation.

The signal element consists

of glass fibre with a strength

< 250 µm. In case of the

signalling membrane being

activated the luminous flux

is interrupted due to the tear

of the optical fibre.

The optional fibre optical

evaluation unit (FOA)

immediately provides an

electrical signal for optical

or acoustic alert that can also

be used to enable system

shut-down or for further data

processing.

At the same time the FOA

fulfils the function of an

opto-electrical converter.


● Zero electrical currentsignalling for use inhazardous areas

● High corrosiveresistance

● Lowest responsepressures for leakagedetection

ELEVENT Breather Valve

Vessels and tanks with low

design pressures are effec-

tively protected against the

effects of excessive pressure

and vacuum with ELEVENT

pressure relief valves. They

systematically and effectively

prevent fugitive emissions of

gas, or other pollutant media,

while at the same time nega-

ting explosive scenarios as

well as from potentially

problematic air intake.

A constant controlled tank

pressure level is assured.

The unique low profile,

compact ELEVENT valve

design is accomplished by

the full deep-drawn stainless

steel metal housing.

Available with multiple

connection options including

sanitary clamp connections

system offers a modular

assembly as well as inter-

changeable components.

Maintenance is a quick

and easy process, requiring

no special tools.

The optimised “air cushion“

sealing principle provides a

smooth valve stroke during

operation and provides repea-

table leak-tight sealing as

well as preventing abrasion

and valve flutter, synonymous

with weight loaded low

pressure applications.

The pioneering breather valve

concept with its deep-drawn

housing presents a flexible

configuration of available

connections, allowing any

client to customise according

to their requirements and

specifications of the facility.

Connection designs with ANSI

flanges, Tri-Clamp and pipe

screw connections compliant

with DIN 11851 as well as CF

and KF flanges are available

on request.

Definition of “Bursting Disc”

Acc. to EN ISO 4126-2

A bursting disc safety device is a non-reclosing pressure relief device used to protect pressure equipment such as pressure vessels, piping, gas cylinders or other enclosures from excessive pressure and/or excessive vacuum.

Acc. to AD 2000-Merkblatt A1 (October 2006 edition)

2.2. Bursting disc devices comprise a bursting element and a clamping device….The bursting elements are ruptured by their response and this results in sudden release of the relief cross-section. In contrast with safety valves, the relief cross-section remains open after the response of the bursting safety devices.

Use of bursting discs (acc. to AD 2000-Merkblatt A1 (October 2006 edition)

2.3 The use of bursting safety devices will be considered if, e.g.

(1) A rapid pressure rise has to be taken into account,(2) The operation conditions can result in deposits and jamming which might impair the efficiency or other safety devices against excess pressure,(3) there are increased seal requirements,(4) large relief cross-sections are necessary.

bursting disc safety device - non-reclosing pressure relief device actuated by differential pressure and designed to function by the bursting of the bursting disc(s), and which is the complete assembly of installed components including, where appropriate, the bursting disc holder

bursting disc assembly - complete assembly of components which are installed in the bursting disc holder to perform the desired function

bursting disc - pressure-containing and pressure-sensitive component of a bursting disc safety device

bursting disc holder - part of a bursting disc safety device which retains the bursting disc assembly in position

conventional domed bursting disc (also referred to as: forward-acting) - bursting disc which is domed in the direction of the bursting pressure (i.e. where the bursting pressure is applied to the concave side of the bursting disc)

slotted lined bursting disc - bursting disc made up of two or more layers, at least one of which is slit or slotted to control the bursting pressure of the bursting disc

reverse domed bursting disc (also referred to as: reverse-acting) - bursting disc which is domed against the direction of the bursting pressure (i.e. where the bursting pressure is applied to the convex side of the bursting disc)

flat bursting disc - bursting disc having one or more layers which is flat when installed. It may be made of a ductile or brittle material

graphite bursting disc - bursting disc manufactured from graphite, impregnated graphite, flexible graphite or graphite composite and designed to burst due to bending or shearing forces

Some Typical Operating Pressures

=


37

• For isolating the safety valve from corrosive media and negating the possibility of product accumulation • Negating unnecessary fugitive emissions (TA Luft = Technical Instructions on Air Quality Control) • For enabling cost effective relief valve material selection irrespective of type of media• For minimising the effects of high temperatures on the relief valve• For avoiding loss of product in the event of a pressure condition • For extensive maintenance cost-savings (In-situ testing of valve is also possible)

• Pressure Relief Valve• Burst Disc Assembly (Disc and Holder)• Tell-tale assembly comprising of: Nipple, T-Piece, Excess Flow Valve and Pressure Gauge.

• When selecting a bursting disc safetydevice the influence of temperatureneeds to be considered. The relevantburst pressure is generally specified atambient room temperature. In case ofdeviating burst temperatures the burstpressures at operating temperature androom temperature are indicated in thetag plate of the bursting disc as well ason the burst test certificate.

• The graph shows the exemplarychange in burst pressure of the burstingdisc manufactured of different materialsas a result of the temperature.
