Safety Check List

โ‘ Read and follow these instructions carefully. Follow your companyโ€™s safety policy and applicable codes and standards.

โ‘ Whenever a PLIDCO product is modified in any form including changing seals by anyone other than the Engineering and Manufacturing Departments of The Pipe Line Development Company or a PLIDCO certified repacking company, the product warranty is voided. Products that are field modified do not have the benefit of the material traceability, procedural documentation, quality inspection and experienced workmanship that are employed by The Pipe Line Development Company.

โ‘ Be absolutely certain that the correct seal material has been selected for the intended use. Contact PLIDCO or an authorized PLIDCO distributor if there are any questions about the seal compatibility with the pipeline chemicals and temperatures.

โ‘ During the Pipe Preparation and Installation procedures, those installing the PLIDCO Flange+Coupling must wear, at minimum, Z87+ safety eyewear and steel toe safety footwear.

โ‘ Determine the type of joint that the PLIDCO Flange+Coupling is expected to connect. See (a) and (b) below and determine the appropriate maximum allowable operating pressure (MAOP) from the ratings listed on the label of the PLIDCO Flange+Coupling.

Page 2 of 12 IP-007 Revision 1

(a) Pipe Unanchored

A PLIDCO Flange+Coupling is considered Unanchored only if it is installed with the clamp and thrust screws, and not welded to the pipe or installed with any other appropriate means of limiting pipe movement and end pull forces.

(b) Anchored Pipe

A PLIDCO Flange+Coupling is considered Anchored if it is welded to the pipe line, or the end pull forces are restricted by other means.

โ‘ The total end pull rating of an Unanchored PLIDCO Flange+Coupling is primarily determined by ability of the clamp screws to resist the PLIDCO Flange+Coupling from being pulled off of the pipe. The rating is provided in terms of pressure. The force can be calculated from the following equation.

Any combination of forces beyond the unachored rating can cause to the fitting to slide or slip off the pipe. Those forces include, but are not limited to: pressure spikes caused by re-pressurizing the pipe too quickly causing an impact load, earth loading such as earthquakes, vibration, gravity loads by supporting large supporting large sections of pipes, thermal stresses, excessive pressure beyond the unanchored rating, bending moments, etc.

The flanged end also limits the end-pull rating. The flange is an ANSI B16.5 or B16.47 flange. Working pressures and forces shall not be exceeded.

โ‘ Pipe wall thickness less than those listed may be pushed inward by the force of the clamp screws. Contact PLIDCO for recommended maximum allowable operating pressure and revised clamp screw torque values for pipe wall thicknesses thinner than listed in Table 1.

Minimum Pipe Wall Thickness for a PLIDCO Flange

Nominal Pipe Size (inches) Wall Thickness (inches)

1ยฝ 0.200 (5.1 mm)

2 0.218 (5.5 mm)

2ยฝ 0.276 (7.0 mm)

3 0.237 (6.0 mm)

4 0.237 (6.0 mm)

6 0.280 (7.1 mm)

8 0.322 (8.2 mm)

10 0.365 (9.3 mm)

12 0.406 (10.3 mm)

14 0.438 (11.1 mm)

16 & larger 0.500 (12.7 mm)

Table 1

โ‘ A PLIDCO Clamp+Ring should be considered whenever the wall thickness is less than those listed. A PLIDCO Clamp+Ring should also be considered where high external forces (such as underwater currents or thermal contractions) are anticipated, even if the pipe has an adequate wall thickness.

Page 3 of 12 IP-007 Revision 1

โ‘ Pipelines should be carefully supported or restrained at elbows and bends to prevent pullouts caused by internal and external forces; or a PLIDCO Clamp+Ring should be used. The pipeline should be evenly supported before re-pressuring. Follow applicable B31 codes during re-pressuring.

โ‘ If the PLIDCO Flange+Coupling is welded according to these instructions, or a suitable PLIDCO Clamp+Ring is used, it can be considered an anchored joint.

โ‘ Observe the pressure and temperature ratings on the label of the PLIDCO Flange+Coupling. Re-pressuring should be accomplished slowly and steadily without surges that could vibrate the pipeline and fitting or pull the fitting off the pipe. Industry codes and standards are a good source of information on this subject. Except for testing purposes, do not exceed the design pressure of the PLIDCO+Flange. Refer to the section on Field Testing for precautions. Personnel should not be allowed near the installation until the seal has been proven.

โ‘ Accurate clamp screw torque values are very important when the PLIDCO Flange+Coupling is used on a pipeline joint that is UNANCHORED. Do not exceed the Pipe Unanchored rating listed on the label of the PLIDCO+Flange until subsequent welding has been completed or the pipe is anchored by other means, such as a PLIDCO Clamp+Ring. FAILURE TO DO SO CAN RESULT IN EXPLOSION, FIRE, DEATH, PERSONAL INJURY, PROPERTY DAMAGE AND/OR HARM TO THE ENVIRONMENT.

Pipe Preparation

1. The pipe surface in the area under and around where the seals should be clean, free of coating and burrs, and lubricated to prevent abrasion to the seals. The area should be blasted to near-white finish, as noted in SSPC-SP10 / NACE No.2, is preferred. The cleaner the pipe the more positive the seal.

2. The seal can tolerate minor surface irregularities up to ยฑ 1/32 inch (0.8 mm). High weld reinforcement or steeply sided welds will need to be ground flush with the pipe outside diameter surface.

3. Pipe outside diameter tolerance is as follows: Nominal pipe size 6-inch and smaller; ยฑ 1% of the nominal diameter Greater than 6-inch through 14-inch; + 1/16 inch (1.6 mm), - 1/8 inch (3.2 mm) Greater than 14-inch nominal diameter; ยฑ 5/32 inch (4.0 mm)

4. For badly misaligned or out-of-round pipe, it is helpful to grind a pilot bevel with a generous taper on the pipe. This will eliminate the risk of damage to the seals while slipping the PLIDCO Flange+Coupling over the end of the pipe. (See Figure 1)

Installation

The seals can be damaged by careless handling. Lifting devices such as chains, cables or lift truck forks should not contact the seals. Failure to do so can result in the seals being damaged, or pulled from their grooves.

1. Measure and record dimension โ€œDโ€, as shown in Figure 2. This will be needed later if the PLIDCO+Flange is welded to the pipe.

2. Coat all exposed surfaces of the seal material with a lubricant. Table 2 indicates the lubricants that are recommended for the various seal materials. The customer must determine if the lubricant is compatible with the product in the pipeline.

Silicone based lubricants = B

Glycerin based lubricants = C

(1) Super Lubeยฎ Grease is a product of Synco Chemical Corporation. (www.super-lube.com)

(2) Temperature limit is for the seal material only and does not imply the pressure rating is necessarily applicable at this limit.

Table 2

NOTE: Do not use a lubricant for underwater applications. Sand, silt or debris could adhere to the lubricant affecting the sealing ability and the accuracy of the torque values.

3. Slide the pipe into the PLIDCO Flange+Coupling so that the end of the pipe is at least 5/8 inch (15.9 mm) past the seal ring (not counting the pilot bevel). The distance from the end of the pipe to the flange face shall not be less than 1/2 inch (12.7 mm). (See Figure 1)

4. Center the PLIDCO+Flange to the pipe. Advance the clamp screws to obtain equal spacing and stick out between the inner diameter of the PLIDCO Flange+Coupling and the outer diameter of the pipe.

5. Install and tighten the flange bolts per ASME PCC-1 before the clamp screws and thrust screws are fully tightened. This is critical if the pipes or components being joined are not free to move. Tightening the flange bolts after the clamp and thrust screws will drag the clamp screw cup points and seal along the pipe, causing damage to both.

6. Determine which clamp screw size is being used, measure the diameter of the threaded end of the clamp screw (measured in inches). As noted in the Safety Check List, contact PLIDCO for the maximum allowable operating pressure and the revised clamp screw torque value for thin wall pipe.

7. Clamp screws must be tightened evenly, maintaining an equal space between the pipe and the coupling using the recommended torque values. Tighten the clamp screws one at a time (torque values in Table 3) in a repeated sequence that matches Figure 3. The first time through the sequence, tighten the screws to 25% of the minimum torque. The second time through, tighten the screws to 50% minimum torque. The third time through, tighten the screws at 100% torque. Then, repeat the sequence at 100% torque until the clamp screws are unable to continue spinning (see Table 4 for torque percentage for each sequence).

Re-pressuring and Field Testing

If the pipeline has been shut down, re-pressuring should be done with extreme caution. Re-pressuring should be accomplished slowly and steadily without surges that could vibrate the pipeline or produce a sudden impact load that could pull the fitting off the pipe. Industry codes and standards are a good source of information on this subject.

Except for testing purposes, do not exceed the MAOP of the PLIDCO fitting. The PLIDCO fitting is designed to be tested up to 1ยฝ times its design pressure. For hydrotesting, PLIDCO recommends following API Recommended Practice 2201, Procedures for Welding or Hot Tapping on Equipment in Service, Section 6.5. The test pressure should be at least equal to operating pressure of the line or vessel, but not to exceed internal pressure by 10%. This is meant to avoid possible internal collapse of the pipe or vessel wall. However, if prevailing conditions could cause collapse of the pipe or pressure walls, the test pressure may be reduced. (See API Standard 510 Section 5.8 for pressure testing precautions.) Personnel should not be allowed near the repair until the seal has been proven.

Field Welding Instructions

Welding is not a requirement for the pressure sealing ability of the PLIDCO Flange+Coupling. The issue of welding is dependent on your companyโ€™s requirements, applicable codes, and if longitudinal loads need to be carried by the PLIDCO Flange+Coupling.

!! WARNING!!

Failure to follow field welding instructions could result in explosion, fire, death, personal injury, property damage and/or harm to the environment.

All of the aspects for in-service welding of PLIDCO Flange+Coupling are not addressed by this document. ASME PCC-2, API 1104 Appendix B, ASME Section IX, PRCI L52047, PRCI Hot Tapยฎ Model, and other industry information pertaining to in-service welding must be considered when planning in-service welding. Refer to IP-019, Welding Considerations for additional information.

It is recommended that the pipeline should be full and under flow.

Welders and weld procedures should be qualified in accordance with API Standard 1104, Welding of Pipelines and Related Facilities, Appendix B, In-Service Welding. We strongly recommend the use of a low hydrogen welding process such as GMAW or SMAW using low hydrogen electrodes (E-XX18) because of their high resistance to moisture pick-up and hydrogen cracking. SMAW electrodes must be absolutely dry. It is very important that the field welding procedure closely follow the essential variables of the qualified procedure so that the quality of the field weld is represented by the mechanical tests performed for the procedure qualification.

Use weld material with equal or greater tensile strength than the pipe. Carefully control the size and shape of the circumferential fillet welds. The weld is required to anchor the joint and give longitudinal stability to the pipeline. The size of the fillet weld should be at least 1.4 times the wall thickness of the pipe. This assumes a 1.0 joint efficiency. You may need to select a different joint efficiency based on your level of inspection or your companyโ€™s welding policy.

Strive for a concave faced fillet weld, with streamlined blending into both members; avoid notches and undercuts. The smoother and more streamlined the weld, the greater the resistance to fatigue failure. The worst possible shape would be a heavy reinforced convex weld with an undercut. Improper weld shape can lead to rapid fatigue failure, which can cause leakage, rupture or an explosion with attendant serious consequences.

Page 11 of 12 IP-007 Revision 1

We do not recommend the use of thermal blankets for pre-heating. Thermal blankets can generate hot spots and reduce the ability of the PLIDCO Flange+Coupling to dissipate welding heat in the vicinity of the seals. We recommend a small torch, such as a cutting torch, being careful not to aim the flame directly into the gap between the PLIDCO Flange+Coupling and the pipe towards the seals. The flame from a preheat torch is helpful in burning off oils and other contaminates. Do not use a large torch, commonly called a rosebud, because of the difficulty controlling the size of the area being preheated.

Dimension โ€œDโ€, as measured during the initial installation, should now be used to mark off locations โ€œAโ€ and โ€œBโ€, as shown in Figure 7. These locations are the same distance from the weld as the seal location โ€œCโ€. To prevent damage to the seals, monitor the heat generated by welding or preheating, particularly at location โ€œAโ€ and โ€œBโ€, by using temperature crayons or probe thermometers. If the heat generated approaches the temperature limit of the seal material, which is indicated in the seal lubrication chart, welding should be discontinued or sequenced to another part of the fitting so that the affected area has a chance to cool.

Welding Sequence

Caution should be taken so that welding or preheating does not overheat the seals. Sequence the welding so that the heat is not concentrated in one area.

1. Cut thrust screws so they are flush with the PLIDCO Flange+Coupling. (See Figure 7)

2. Add a fillet weld to the PLIDCO Flange+Coupling around the circumference of the pipe and seal the ends of the cut off thrust screws. (See Figure 7)

3. Cut or burn off clamp screws approximately 3/16 inch (4.8 mm) above the outside surface of the coupling and seal weld. After the circumferential fillet welds are finished, one clamp screw per end may be removed to serve as a vent while welding and also as a final test point for leakage. (See Figure 7)

4. For information on hydrotesting welds before putting the line back into service, read IP-053. Contact PLIDCO for additional information.

Figure 7

Storage Instructions

PLIDCO Flange+Couplings should be stored in a dry environment to prevent the unpainted surfaces from rusting. Storage temperatures should not exceed 120ยบF (50ยบC). Cover with a tarp made of dark polyethylene, box, etc. to keep the direct sunlight from the seals. It is best to exclude contamination, light, ozone, and radiation. Improperly stored PLIDCO Flange+Coupling can cause the seal material to become cracked and brittle and lose its ability to seal.

Traceability

PLIDCO Flange+Couplings, as with most PLIDCO products, have a unique serial number by which the fitting body material is fully traceable. Additionally, all elastomer seals have a unique batch number by which the seal material is traceable.

Recommended Inspection Schedule

1. After the pipeline is re-pressurized and field tested (see Re-pressuring and Field Testing for precautions), the torque values should be checked again 4 hours after installation. Then, the torque values should be checked again 24 hours after that.

2. It is recommended that torque striping be applied from the threads of all the screws to the body of the PLIDCO Flange+Coupling so that any loosening of the screws can be visually seen during an inspection.

3. 6 months after installation, it is recommended that a visual inspection occurs that checks for visible signs of leakage, bolt/nut loosening, and general wear or corrosion.

4. After the 6-month inspection, a yearly visual inspection is recommended that checks for visible signs of leakage, bolt/nut loosening, and general wear or corrosion.
