API SPEC 15PX pdf download Specifcation for Crosslinked Polyethylene (PEX) Line Pipe
1 Introduction1.1Purpose
The purpose of this specification is to provide standards for crosslinked polyethylene (PEX) line pipe suitable foruse in conveying oil, gas,and nonpotable water in underground, aboveground, and reliner applications for theoil- and gas-producing industries.
This specification does not address all of the safety concerns associated with the design, installation, or use ofproducts suggested herein. lt is the responsibility of the user of this specification to make appropriate health andsafety considerations.
All pipe produced under this specification use pressure-rated materials used in pressurized, non-pressure, andnegative pressure applications.
The technical content of this document provides requirements and guidelines for performance, design, materialsinspection, dimensions and tolerances, marking, handling, storing, and shipping.
This specification covers PEX line pipe used for the production and transportation of oil, gas, and nonpotablewater. This specification does not cover pipe for chlorinated water service. The piping is intended for use in newconstruction, structural pressure-rated liner,line extension, and repair of both aboveground and buried-pipeapplications.Equipment covered by this specification is listed as follows:
a) PEX line pipe;
c)metallic flange couplers for field installations and PEX face flanges used as internal diameter adapters.1.3Service Conditions
The standard service conditions for the API 15PX standard pressure rating are as follows:a)non-chemically-aggressive fluids;
b) operating temperature range:-50 °C (-58 °F) to 93 °C (200 °F) or 95 °C (203 °F), depending on design
methodology (Section 4).
NOTE Applications above 95°C(203 °F) require special design consideration; service conditions other than the standardAPI15PX conditions and their effects on design are discussed in Section 4.
