API SPEC 15LR
Specification for Low Pressure Fiberglass Line Pipe
|Publication Date:||1 August 2001|
This speciÞcation covers Þlament wound (FW) and centrifugally cast (CC) Þberglass line pipe and Þttings for pipe in diameters up to and including 24 in. in diameter and up to and including 1000 psig cyclic operating pressures. In addition, at the manufacturerÕs option, the pipe may also be rated for static operating pressures up to 1000 psig. It is recommended that the pipe and Þttings be purchased by cyclic pressure rating. The standard pressure ratings range from 150 psig to 300 psig in 50 psig increments, and from 300 psig to 1000 psig in 100 psig increments, based on either cyclic pressure (ref. 5.5.1) or static pressure (ref. 5.5.2). Quality control tests, hydrostatic mill tests, dimensions, weights, material properties, physical properties, and minimum performance requirements are included.
A decimal/inch system is the standard for the dimensions shown in this speciÞcation. Nominal sizes will continue to be shown as fractions. For the purposes of this speciÞcation, the fractions and their decimal equivalents are equal and interchangeable. Metric conversions are described in Appendix G.
