Easy to InstallThe Unifit Premier Series is pre-assembled with lubricated gaskets. The captivated non-rotating bolt heads require a single spanner to install. These features enable a smooth and simple installation in even the most challenging conditions.

Extensive RangeFrom DN40-DN600mm. The Unifit Premier Series includes: - Wide range couplings - Universal drilling, wide range flange adaptors.

Unifit Premier Couplings

Specifications

Unifit Premier couplings can be used as step couplings across pipes within the working tolerance. For example a TC0150-2 (159-182mm) can be used to join a 160mm PVC pipe to a 177mm OD Asbestos Cement pipe.

Available Range & Working PressureThomas Unifit Premier couplings and universal drilling flange adaptors incorporate a pre-lubricated thick tapered runner seal. Thus enabling a simple and quick installation of the product over a wide range of pipe outside diameters. Unifit Premier products are available from: DN40-DN600mmStandard working pressure WP = 1600 kPa (16Bar)Test pressure = 1.5 x WP

Working ToleranceUnifit Premier couplings are wide tolerance product designed to fit all popular rigid pipe sizes, thus dramatically reducing the number of product to be stocked foor maintenance purposes. Unifit Premier products have working tolerances up to 23mm. Such as the TC0150-2 that ranges from 159-182mm.

Pipe End MisalignmentIt is good engineering practice to align pipes correctly before joining them with a mechanical coupling. Unifit couplings can accommodate a small degree of pipe end misalignment.

For Pipe O.D < 300mm Maximum misalignment = 1% of pipe O.D.For Pipe O.D. > 300mmMaximum misalignment = 3mm of pipe O.D.

Coating Hanging RingNOTE:Products may be supplied with a ring to assist during the coating process, this is not a lifting eye for a complete product.

Angular DeflectionThomas Unifit Premier couplings allow a certain degree of angular deflection between pipe ends. The maximum admissible angular deflection permitted by a coupling is determined by the OD of the pipe being joined.

SETTING GAPSRECOMMENDED GAP

Bolt Torque RatingTo assure correct rubber seal compression, bolts must be tightened in diametrically opposite pairs, similar to the way a motor vehicle wheel is tightened. Bolt up evenly giving the nuts 2 or 3 turns at a time to the prescribed torque rating below:

Galvanized Bolts:M12 - Torque 70-80Nm, use a 19mm Spanner.M14 - Torque 90-100Nm, use a 22mm Spanner.M16 - Torque 100-120Nm, use a 24mm Spanner.

Stainless Steel Grade 316 Bolts (with lubricant):M12 - Torque 65-70Nm, use a 19mm Spanner.M14 - Torque 90-100Nm, use a 22mm Spanner.M16 - Torque 100-120Nm, use a 24mm Spanner.

If an effective seal is not attained, the coupling must be loosened, lubricant must be applied to the rubber seal inside and outside. The coupling must be realigned and re-tightened.

It is good engineering practice to visit the site and re-check the torque rating 24 hours after installation.

NOTE:Stainless Steel bolts must be tightened with a dry film lubricant (Teflon) or wet lubricant (Nickel Slip). If a lubricant is not used the chances are high that the nut will seize on the bolt thread. It will be necessary to cut off the bolt and replace it.

Special Unifit CouplingsCouplings can be manufactured including:- Special materials such as full Stainless Steel Grade 304 & 316 product- Stainless Steel bolts, nuts & washers- High Pressure couplings up to PN64- Special sizes- Special coatings

Long Barrel couplings are able to accommodate larger setting gaps.

Pipe End Thrust, Restraint & InstallationInternal pressure forces attempt to separate pipeline components, most notably at tees, bends and blank ends.

NOTE:Couplings are NOT DESIGNED TO RESIST END LOAD due to pressure forces. End thrust restrained must be provided by other means.

When placing thrust blocks and anchoring pipe with concrete, do not encase couplings in concrete. Leave couplings exposed during testing. The manufacturer can not be held liable for excavating leaking couplings.

Additionally, step couplings must be anchored to avoid couplings ‘sliding’ along the pipe. Wide range couplings operating at both extremities of its working tolerance may also ‘slide’ with sufficient internal pipeline pressure. For example, an exposed (not buried) TC300-2 Coupling (315-332mm) that is joining a 315mm PVC pipe to a 332mm OD AC pipe may slide at as little as 10-12 bar. In these conditions the coupling must be restrained. Contact our offices for solutions.

Unifit Premier Universal Flange Adaptors



J8

BenefitsUnifit Premier Universal Flange Adaptors exhibit a universal flange drilling enabling the adaptor to be connected to multiple flange drillings. Steel flange adaptors have a single specified flange drilling. For example BS4504 PN16, whereas Universal flange adaptors can accommodate multiple flange drillings including: 10 and 16 bar rated flanges from SANS1123, BS EN1092-1, ISO7005 1:1992 and additional certain BS10:1962 (Table D&E), certain ANSI & AWWA flange drillings.

ApplicationUnifit Premier Universal Flange Adaptors are designed for use on air, water, sewer and gas pipelines. The Universal Adaptor exhibits the same wide sealing tolerance of the Unifit Coupling and can therefore be used to join multiple pipe outside diameters and different pipe materials.

The universal drilling consists of elongated flange holes enabling the adaptor to be bolted to multiple flange drillings.

Pipe Angular DeflectionAll models accommodate angularity between pipes which allows for normal pipeline movement caused by ground settlement. Universal flange adaptors have a total allowable angular deflection of up to 3°.

Easy to InstallThe Unifit Premier Series is pre-assembled with pre-lubricated rubber seals. The captivated non-rotating bolt heads require a single spanner to tighten. These features enable a smooth and simple installation in even the most challenging conditions.

Performance CharacteristicsThe abi l i ty of a Unif i t Universal Adaptor to accommodate angular deflection, pipe expansion and contraction etc. equals half the documented value for an equivalent sized Unifit Coupling. For example, a TC300-2 coupling can accommodate 6° of pipe angular deflection. The similar sized TUF300-2 Universal Flange Adaptor can accommodate 3° degrees of pipe angular deflection. Similarly setting gaps and pipe end preparation distances are half those specified for Unifit Couplings.

Dimensions

Sizes up to DN600mm availableStandard sizes tabled belowStandard Working Pressure WP=1600kPaTest Pressure TP=1.5xWP=2400kPa

Unifit Premier Universal Flange Adaptors suit the popular flange drilling specifications below: - BS10 Table D & Table E - SABS1123 T1000/3 & T1600/3 - BS4504 PN10 & PN16 - BS EN1092-1 PN10 & PN16 - ISO 7005 1:1992 PN10 & PN16.


All Unifit Premier Universal Flange Adaptors are Full Through Bore flange adaptors. This means the flange adaptor is not a reducing step flange adaptor, therefore enabling the installer to slide the entire adaptor over the pipe for which it is intended. A reducing step flange adaptor has a smaller flange ID. Therefore the pipe can not pass completely through a reducing step flange adaptor.
