API 15S, 3rd Edition – Spoolable Reinforced Plastic Line Pipe

API 15S provides requirements for the manufacture and qualification of spoolable reinforced plastic line pipe in oilfield and energy applications, including transport of multiphase fluids, hydrocarbon gases, hydrocarbon liquids, oilfield production chemicals, and nonpotable water. Also included are performance requirements for materials, pipe, and fittings.

These products consist of a liner, a reinforcement layer consisting of helically wrapped steel or nonmetallic reinforcing elements, and an outer cover. The spoolable reinforced line pipe under this specification is capable of being spooled for storage, transport, and installation. For offshore use, additional requirements may apply and are not within the scope of this document.

This specification is limited to pipe and end fittings and couplings and does not relate to other system components and appurtenances. Where other system components (e.g., elbows, tees, valves) are of conventional construction, they will be governed by other applicable codes and practices.

Products manufactured and qualified to this specification are eligible for participation in the API Monogram Program.
