WARNING: IMPORTANT SAFETY INFORMATION ENCLOSED. READ THIS OPERATING AND MAINTENANCE INSTRUCTIONS MANUAL BEFORE OPERATING PRODUCT.

WARNING: THIS INFORMATION MUST BE AVAILABLE TO ALL PERSONNEL THAT WILL OPERATE AND MAINTAIN EQUIPMENT. FAILURE TO READ, UNDERSTAND AND FOLLOW THE OPERATING

AND MAINTENANCE INSTRUCTIONS MANUAL COULD RESULT IN SERIOUS BODILY INJURY, DEATH, OR PROPERTY DAMAGE.

Most SPM®

products generate, control, or direct pressurized fluids; therefore, it is critical that those who work with these products be thoroughly trained in their proper application and safe handling. It is also critical that these products be used and maintained properly. SPM® flow products contain elastomeric seals and are not intended to provide proper functionality when exposed to fire.

WARNING: MISUSE, SIDE LOADING, IMPROPER MAINTENANCE, OR DISASSEMBLY UNDER

PRESSURE CAN CAUSE SERIOUS BODILY INJURY, DEATH, OR PROPERTY DAMAGE.

The following information is given in good faith and should aid in the safe use of your SPM® products. This information is not meant to replace existing safety policies or practices of your company. Personal Responsibilities:

1. When working on SPM® flow control products, safety glasses, approved safety shoes, and hard hat

must be worn. 2. Personnel should never hammer on any component when pressure is present. Hammering on any part

or component may also cause foreign material or steel slags to become airborne.

3. It is a personal responsibility to use the proper tools when servicing the valve. It is a personal responsibility to be knowledgeable and trained in the use and handling of tools for all maintenance of the valve.

4. Hot surface may be present; it is a person’s own responsibility to protect against burn injuries.

On Location:

Each valve is clearly marked with a maximum pressure rating. This pressure must not be exceeded or SERIOUS BODILY INJURY, DEATH, OR PROPERTY DAMAGE MAY OCCUR.

1. The valve discharge connections should be properly cleaned and lightly oiled before the downstream piping is attached. Any worn, damaged, or missing seals should be replaced.

2. Welding, brazing, or heating any part of the product is prohibited. If accessories must be attached,

consult Weir Oil & Gas prior to installation.

3. A complete visual inspection of the product must be made prior to each use. Any leaking seals, broken bolts, leaking hoses, or improperly tightened parts must be remedied prior to using.

4. Any repairs or service (even routine maintenance) performed on the product must be performed by a

trained service technician who is qualified to work on high pressure flow control products. All such service and repairs must be supervised by qualified management personnel or returned to Weir Oil & Gas for service. Only SPM® replacement parts should be utilized. Failure to do so may result in loss of warranty as well as SERIOUS BODILY INJURY, DEATH, OR PROPERTY DAMAGE.

Special Precautions:

1. The modifications to or unauthorized repair of any part of a SPM® product, or use of components not qualified by Weir Oil & Gas, can lead to damage or failure and SERIOUS INJURY OR DEATH.

2. All SPM® threaded components are right hand threaded unless specifically designated otherwise. Any

turning counterclockwise will unscrew the assembly. Make sure all threaded components are assembled to the correct torque value.

3. All products should be properly cleaned, greased, or oiled after each use and inspected prior to each

use.

4. Each integral union connection is clearly marked with a pressure code (i.e. “1502”, 15,000 PSI). This pressure must not be exceeded. This code should also be used with mating unions. Improper mating can result in failures. All integral union connections used must match (according to size, pressure rating, etc.). These connections must also match the service of the designated string they are installed in.

WARNING: OBSERVE ALL INSTRUCTIONS, CAUTIONS, AND WARNINGS AS NOTED IN THIS MANUAL. FAILURE TO DO SO CAN LEAD TO EQUIPMENT DAMAGE AND SERIOUS BODILY

INJURY, DEATH, OR PROPERTY DAMAGE.

Product Description: Weir has expanded its comprehensive suite of overpressure relief products to fit a wide range of operational requirements. Intended to be used in concert with SPM® Nitrogen or Spring Relief valves, the SPM® EXL Pressure Relief Disc is designed to provide an additional level of protection for personnel and equipment should an overpressure event occur during pumping operations. The SPM® EXL Pressure Relief Disc features a replaceable disc, which can easily be changed on site, allowing for flexibility in pressure ratings as well as lower replacement cost. This device requires minimal maintenance and provides controlled discharge within a small tolerance band of the desired rupture rating. A variety of rupture disc kits are available to install into the assembly; depending on the desired pressure needed. The design of the product helps facilitate the correct installation orientation of all components. Housing assemblies will only come with the main body, hex nut and rupture disc catcher as shown below. Use page 5 to determine what Rupture Disc Kit will be needed for the desired burst pressure.

Relief tolerance of +/- 5% to rated disc pressure Suitable for pumping operations at no more than 90% of the marked burst pressure without reduction in service life. Operating above that range will introduce fatigue to the disc reducing functional life of the product and it may result in premature rupture of the disc. Flow rate capability (@ 42/fps):

WARNING

RUPTURE DISC MAY FRACTURE UPON ACTIVATION. USERS MUST TAKE PRECAUTIONS TO ENSURE THAT THE EXL PRESSURE RELIEF DEVICE IS ORIENTED SUCH THAT PERSONNEL OR EQUIPMENT

ARE NOT IN LINE OF THE DISCHARGE OUTLET.

WARNING

NEVER BLOCK THE DISCHARGE OUTLET OF THE EXL PRESSURE RELIEF DEVICE.

WARNING: DISASSEMBLY UNDER PRESSURE CAN CAUSE SERIOUS BODILY INJURY, DEATH, OR PROPERTY DAMAGE.

Always Remember:

1. Always wear PPE (personal protective equipment). 2. Only qualified technicians should perform maintenance on SPM® products. 3. Always use SPM® supplied new parts kit for reassembly. 4. Clean all components thoroughly prior to reassembly. 5. Check sealing surface area for pitting, erosion or other flaws. 6. Use only SPM® parts on SPM® products. 7. This device is intended to discharge atmospherically when it relieves.

Maintenance Requirements: Weir recommends that the rupture disc be removed from service after 250 working hours or 100 stages, whichever comes first.

Vessel Test Procedures: Prior to shipment, product testing procedure 4S12497 requires that each rupture disc body pass a one-time vessel test at 150% it’s rated working pressure; then, when conducting subsequent vessel tests on used housings, limit the pressure to 100% of rated working pressure as required by 4S12497. Housings should always be vessel tested in accordance with product testing procedure 4S12497. Utilize the correct dummy seat for the appropriate size (2" - 2P42526, 3" - 2P42280). During the vessel testing the O-ring and hex nut shall be used.
