Standard Specification for High-Density Polyethylene (PE) Line Pipe

Fecha:
2020-06-04 /Active
Abstract:

This specification covers the requirements and test methods for high-density polyethylene (PE) materials, line pipes, and fittings used in pressure or non-pressure oil and gas producing applications to convey fluids such as oil, dry or wet gas, multiphase fluids, and non-potable oilfield water. This specification does not apply to pipes for gas distribution applications. PE material compounds suitable for use in the manufacture of pipes and fittings under this specification shall adhere to values of the following properties: density (natural base resin), melt index, flexural modulus, tensile strength at yield, SCG resistance, hydrostatic strength, color and UV stabilization, hydrostatic design stress, and hydrostatic design basis. The line pipes shall meet specific requirements as to workmanship, dimensions (outside diameter, toe-in, outside surface irregularity, ovality, wall thickness, and special sizes), inside surface ductility, tensile elongation, bendback resistance, elevated temperature sustained pressure, short-term strength and pressurization, apparent tensile strength at yield, and carbon black content. And conversely, PE fittings shall be manufactured in accordance with their intended use with correspondingly sized PE line pipes, as follows: socket fusion fittings, butt fusion fittings, electrofusion fittings, fabricated fittings, and transition fittings.

Scope:

1.1 This specification covers requirements and test methods for high-density polyethylene (PE) materials, pipe and fittings for pressure or non-pressure oil and gas producing applications to convey fluids such as oil, dry or wet gas, multiphase fluids, and non-potable oilfield water. This specification does not cover pipe for gas distribution applications.

1.1.1 For the purposes of this specification, high-density polyethylene material is Specification D3350 density cell classification 3 or higher. This specification does not cover materials having Specification D3350 density cell classification less than 3 such as medium or low density polyethylene materials.

1.1.2 See Specification D2513 for polyethylene pipe and fittings intended for use in the distribution of natural gas, or for use with liquefied petroleum gas.

1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 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.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
