1. Scope
1.1 This specification covers requirements and test methods for 1 ⁄ 2 in. through 14 in. multilayer polyethylene-polyamide (PE-PA) pipe, which is a two-layer pipe (PE pipe layer bonded to an inner layer of PA). The multilayer pipe covered by this specification is intended for use in piping applications where the permeation and chemical resistance of polyamide (PA) compounds may be useful to protect the PE pipe layer, such as oil and gas producing applications that convey oil, dry or wet gas, and multiphase fluids. N OTE 1—Permeability and chemical resistance depends on the type of PA used. The PA layer delays but does not prevent liquid hydrocarbons effects. Therefore, the hydrocarbon chemical design factor for this multilayer pipe should be the same as for PE pipe layer—see X1.2. 1.2 Electrofusion and mechanical joints are typically used for this multilayer pipe. 1.3 Unless specified otherwise, all the pipe requirements in this specification are for the multilayer pipe. 1.4 The PA layer is not taken into consideration for the design pressure of multilayer pipe meeting this specification. Design pressure rating is determined from the PE pipe layer alone—see Appendix X1. 1.5 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.6 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in figures and tables) shall not be considered as requirements of the standard. 1.7 The following precautionary caveat pertains only to the test method portion, Section 6, of this specification. This standard does not purport to address all ofthe safety concerns, ifany, associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
4. Compound Requirements
4.1 PE Compound Requirements—The PE compound used to make the PE pipe layer shall be virgin compound and shall have a Plastics Pipe Institute (PPI) hydrostatic design basis (HDB) rating in accordance with PPI TR-3 using Test Method D2837. The PE compound used for the PE pipe layer shall have a pipe material designation code ofPE 4710 in accordance with PPI TR-3 Section F.7 and shall be listed in PPI TR-4, and shall meet Specification D3350 requirements, with a minimum cell class of 444474C. 4.1.1 Additive Classes—PE compounds shall be Code C as defined in Specification D3350. Code C compound shall contain 2.0 to 3.0 percent carbon black as measured by Test Method D1603 or D4218. The pipe manufacturer shall mea- sure carbon black content of the compound once per week. 4.1.2 Chemical Resistance—Testing shall be conducted per 6.10 on specimens of PE compound from compression molded plaques or from a ring specimen prepared from pipe. N OTE 2—This test is only an indication of what may happen as a result of short-term exposure to these chemicals. Contact the manufacturer for specific chemical resistance information for this product. 4.1.3 Elevated Temperature—The PE 4710 compound shall have an HDB at 140 °F (60 °C) ofat least 1000 psi listed in PPI TR-4. 4.2 PA Compound Requirements—The PA compound shall be a non-reinforced PA with the three-digit cell class (group, class, grade) in accordance with Classification D6779 per Table 1. 4.2.1 Chemical Resistance—Based on the intended applica- tion and the corresponding need for chemical resistance, the multilayer pipe manufacturer shall provide chemical resistance properties for the type of PA compound used in the PA layer of this multilayer pipe. 4.2.2 Color—The PA layer shall have a different color from the black PE pipe layer so that it can be easily recognized, such as the APWA color coding system of yellow for gas and oil lines.
