Standard Specification for Polyethylene (PE) Plastic Pipe (SDR-PR) Based on Outside Diameter
This specification covers polyethylene (PE) pipe made in dimensions based on outside determined range of diameters and larger. The piping is intended for new construction and insertion renewal of old piping systems used for the transport of water, municipal sewage, domestic sewage, industrial process liquids, effluents, slurries, etc., in both pressure and nonpressure systems. Different dimensional properties of pipes like outside diameter, wall thickness, eccentricity, toe-in, and special sizes shall be determined. Physical properties such asdensity, melt index, flexural modulus, tensile strength, slow crack growth resistance, hydrostatic strength, color and UV stabilizer, HDB, and HDS shall determined as well. In order to determine the performance of pipes under pressure the following tests shall be done: short-term pressurization test and elevated temperature sustained pressure test. The pipe shall be homogeneous throughout and essentially uniform in color, opacity, density, and other properties. The inside and outside surfaces shall be semi matte or glossy in appearance (depending on the type of plastic) and free of chalking, sticky, or tacky material. The surfaces shall be free of excessive bloom, that is, slight bloom is acceptable. The pipe walls shall be free of cracks, holes, blisters, voids, foreign inclusion, or other defects that are visible to the naked eye and that may affect the wall integrity. Holes deliberately placed in perforated pipe are acceptable. Bloom or chalking may develop in pipe exposed to direct rays of the sun (ultraviolet radiant energy) for extended periods and, consequently, these requirements do not apply to pipe after extended exposure to direct rays of the sun.
1.1 This specification covers polyethylene (PE) pipe made in dimensions based on outside diameters of 90 mm (3.500 in.) and larger.
1.2 Three standard outside diameter sizing systems are detailed: one known as the ISO metric system, one known as the IPS system, and the other known as the DIPS system. See 5.2.5 for guidelines for special sizes.
1.3 The piping is intended for new construction and insertion renewal of old piping systems used for the transport of water, municipal sewage, domestic sewage, industrial process liquids, effluents, slurries, etc., in both pressure and nonpressure systems.
Note 1—The user should consult the manufacturer to ensure that any damage to the polyethylene pipe caused by the material being transported will not affect the service life beyond limits acceptable to the user.
1.4 All pipes produced under this specification are pressure-rated. See Appendix X5 for information on pressure rating.
Note 2—References and material descriptions for PE2406, PE3406, PE3408 and materials having a HDB of 1450 psi have been removed from Specification F 714 due to changes in Specification D 3350 and PPI TR-3. For removed designations, refer to previous editions of Specification F 714, Specification D 3350, PPI TR-3 and PPI TR-4. The removal of these materials does not affect pipelines that are in service. See Notes 9 and 10.
1.5 This specification includes criteria for choice of raw material, together with performance requirements and test methods for determining conformance with the requirements.
1.6 Quality-control measures are to be taken by manufacturers. See Appendix X4 for general information on quality control.
1.7 In referee decisions, the SI units shall be used for metric-sized pipe and inch-pound units for pipe sized in the IPS system (ANSI B36.10) and DIPS system. In all cases, the values given in parentheses are provided for information only.
1.8 The following safety hazards caveat pertains only to the test methods portion, Section 6, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
