Standard Specification for Multilayer Polyethylene-Polyamide (PE-PA) Pipe for Pressure Piping Applications

ABSTRACT
This specification establishes the 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). It covers the multilayer pipe for use in piping applications where the permeation and chemical resistance of 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. Electrofusion and mechanical joints are typically used for this multilayer pipe.
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.
Note 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 of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Overview

ASTM F2807-13(2018) specifies the requirements and test methods for multilayer polyethylene-polyamide (PE-PA) pipe ranging from 1/2 inch to 14 inches in diameter. This standard, issued by ASTM International, covers two-layer pressure pipes consisting of an outer PE layer bonded to an inner PA layer. The design addresses the need for improved chemical resistance and reduced permeation in demanding piping applications, particularly in the oil and gas sector. Typical applications include conveying oil, dry or wet gas, and multiphase fluids, where the polyamide (PA) inner layer protects the polyethylene (PE) layer from aggressive chemical environments.

Key Topics

• Scope and Construction: Details the composition of PE-PA pipes, focusing on a PE outer layer and a chemically resistant PA inner layer. The PA layer is designed to enhance permeation and chemical resistance but does not contribute to structural pressure resistance.
• Performance Requirements: Defines dimensional tolerances, wall thicknesses, ovality limits, and burst strength. All pressure and mechanical property evaluations pertain to the PE pipe layer, as the PA layer serves only a protective function.
• Testing and Compliance: Establishes protocols for sustained pressure testing, hydrostatic burst tests, tensile strength, adhesion between layers, permeability, and chemical compatibility. Compliance with these requirements helps ensure product quality and consistent field performance.
• Marking and Traceability: Outlines strict requirements for pipe marking, including clear material identification, manufacturer information, production date, and batch codes, ensuring full traceability for quality assurance.
• Joining Methods: Specifies that electrofusion and mechanical joining techniques are commonly used for connecting multilayer pipes. Heat fusion is permitted when no hydrocarbons are present at the joint interface.

Applications

ASTM F2807-13(2018) multilayer PE-PA pipes are primarily suited for the following pressure piping applications:

• Oil and Gas Production: Used in gathering lines and transmission systems where fluids may contain corrosive chemicals or hydrocarbons. The PA inner layer offers an additional barrier, extending pipe life in challenging environments.
• Multiphasic Fluid Transport: Effective for pipelines carrying mixtures of oil, gas, and other substances, where permeation resistance and chemical protection are essential for safety and longevity.
• Gas Distribution: The multilayer design provides enhanced safety for transporting dry or wet gases and helps prevent contamination or environmental release.
• Industrial Piping Systems: Suitable for pressure applications requiring robust chemical and permeation resistance, such as in chemical plants and processing facilities.

Related Standards

Several key ASTM, ISO, and national standards are referenced by or related to ASTM F2807-13(2018):

• ASTM D1598 & D1599: Test methods for time-to-failure and short-term hydraulic pressure resistance of plastic pipe.
• ASTM D2837: Methods for determining the hydrostatic design basis for thermoplastic piping materials.
• ASTM F1290: Practice for electrofusion joining of polyolefin pipes.
• ISO 1167 & ISO 3126: International standards for the resistance of thermoplastic pipes to internal pressure and for measurement of pipe dimensions.
• Plastics Pipe Institute (PPI) TR-3 & TR-4: Guidelines on hydrostatic design basis ratings and pressure design factors for thermoplastic pipes.
• SAE J 2260 and EN 14125: Industry-specific standards for multi-layered nonmetallic fuel system tubing and thermoplastic pipework.

By conforming to ASTM F2807-13(2018), manufacturers, designers, and installers can ensure that multilayer PE-PA pressure pipes deliver enhanced performance, safety, and reliable service in chemically challenging and high-pressure environments. This standard supports robust material selection, testing, and traceability practices, all vital in maintaining the integrity of critical piping systems.
