Full title and description

St API RP 15SIH-2021 — Installation and Handling of Spoolable Reinforced Line Pipe. This recommended practice provides guidance for onshore installation, field handling, storage, unspooling, connection assembly, and pre-service verification of spoolable reinforced plastic line pipe (API Specification 15S products) to avoid damage to the pipe and field fittings and to assure assembly integrity prior to use.

Abstract

This document establishes recommended practices for safe and damage‑minimizing procedures when transporting, storing, unspooling, laying, joining and commissioning spoolable reinforced line pipe systems. It addresses protection of the pipe jacket and reinforcement, handling limits (including bending and tension guidance), recommended checks for fittings and couplings, field-assembly precautions, and pre-service tests such as field hydrotesting and annulus/shield integrity checks. The guidance is written to complement API Specification 15S product requirements and to help owners, installers and inspectors achieve reliable, leak‑free field installations.

Scope

Applies to onshore installation and handling practices for spoolable reinforced plastic line pipe manufactured to API Specification 15S. The recommended practice covers receipt, storage, inspection, loading/unloading, towing/unspooling, laying, assembly of field fittings and connectors, recommended limits for bending and tension during handling, protection from mechanical and environmental damage, and requirements for field testing and commissioning prior to service. It is intended for use where spoolable line pipe is deployed as product, service or utility lines and where field‑assembled connections and fittings are required.

Key topics and requirements

• Pre‑installation inspection and receipt checks for spooled pipe and field fittings.
• Storage, stacking and UV/mechanical protection recommendations to prevent jacket and reinforcement damage.
• Handling limits: recommended bending radii, allowable tension, and spooling/unspooling procedures.
• Safe procedures for assembly of couplings, connectors and end‑fittings to ensure leak‑tight joints.
• Field testing and commissioning: recommended hydrostatic and annulus/shield checks prior to commissioning.
• Risk mitigation practices for transport, crossing of obstacles, and above‑ground versus buried installation options.
• Inspection, documentation and traceability expectations to support integrity management.

Typical use and users

Used by operators, pipeline installation contractors, integrity and commissioning engineers, field supervisors, inspection authorities, OEMs and suppliers of spoolable reinforced line pipe systems. Typical applications include produced‑fluid transfer, flowlines, tie‑backs, water injection or produced water lines, temporary or rehabilitation pipeline installations where spoolable systems offer faster installation and corrosion resistance advantages.
