New Specification for MRS-Rated Metric- and Inch-sized Crosslinked Polyethylene (PEX) Pressure Pipe for Gas Gathering Applications Project Number 68-22-01
1. Scope
This specification covers crosslinked polyethylene (PEX) pipe that is outside diameter controlled in metric pipe sizes (DN 16 to 1000) and inch pipe sizes (NPS 3 to 54), and pressure rated (see Appendix X1) using the MRS rating system. This Specification is intended for PEX pipe made by various processes, as long as the PEX pipe made by that process meets all the requirements of this Specification. Included are requirements and test methods for material, workmanship, UV protection, dimensions, hydrostatic sustained pressure, stabilizer functionality, bent-pipe hydrostatic pressure, chemical resistance, minimum operating temperature, degree of crosslinking, squeeze-off, and hydrostatic burst pressure. Requirements for pipe markings are also given. The pipe covered by this specification is intended for gas gathering or oil and gas applications.
Keywords
PEX, gas gathering, MRS, CRS
Rationale
This standard would be used by gas operators in the gas gathering industry who want to use the benefits of the MRS and CRS methods.
The title and scope are in draft form and are under development within this ASTM Committee.
