API - SPEC 15LR
Specification for Low Pressure Fiberglass Line Pipe
|Publication Date:||1 January 1990|
1.1 Coverage. This specification covers centrifugally cast (CC) and filament wound (FW) fiberglass line pipe and fittings for these pipe in diameters up to and including 16 inches rated for cyclic operating pressures up to and including 1000 psig. It is recommended that the pipe and fittings be purchased by pressure rating. The standard pressure ratings are 150 psig, 200 psig, 250 psig, and 300 psig. Pipe with pressure ratings greater than 300 psig can be purchased in 100 psig increments all based on cyclic pressures. For static pressure conditions higher pressure ratings may be used [refer to Par. 4.5(b)]. Quality control tests, hydrostatic mill tests, dimensions, weights, material properties, physical properties, and minimum performance requirements are included.
