ASTM-F1335 › Standard Specification for Pressure-Rated Composite Pipe and Fittings for Elevated Temperature Service (Withdrawn 2011)
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers pressure-rated composite pipe and fittings for the transport of hot or cold liquids, beverages, or gases that are compatible with the composite pipe and fittings. Composite pipe is produced using a butt welded aluminum pipe as a core, with an extruded inside layer of cross-linked polyethylene (PEX) or polyethylene (PE). An adhesive layer is used to bond the inside layer to the wall of the aluminum pipe. An outer layer of polyethylene (PE) and an adhesive layer are extruded to the outer wall of the aluminum pipe. The following test shall be performed to conform with the specified requirements: composite pipe and fittings qualification test; hydrostatic sustained pressure test; vacuum depression test; hot and cold pressure cycling; water hammer test; delamination; fusion line test; and gel content.
Scope
1.1 This specification covers pressure-rated composite pipe and fittings for the transport of hot or cold liquids, beverages, or gases that are compatible with the composite pipe and fittings.
1.2 Composite pipe is produced using a butt welded aluminum pipe as a core, with an extruded inside layer of crosslinked polyethylene (PEX) or polyethylene (PE). An adhesive layer is used to bond the inside layer to the wall of the aluminum pipe. An outer layer of polyethylene (PE) and an adhesive layer are extruded to the outer wall of the aluminum pipe.
1.3 Composite pipe is produced in four configurations and referenced in Fig. 1, as Classes 1, 2, 3, and 4 composite pipe.
1.4 This specification includes compression fittings and compression joints, which are referenced in . Compression fittings as described in this specification are not compatible for gas transportation. Threaded fittings are referenced in .
1.5 The following precautionary caveat pertains only to the test method portion 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.
1.6 The values stated in acceptable SI units are to be regarded as the standard. The values given in parentheses are provided for information only. The values stated in each system are not exact equivalents, therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
