非粘接柔性管规范 (第4版)
First Principles Analysis
1. Scope
This specification covers unbonded flexible pipe for offshore oil and gas applications including risers, flowlines, and water injection lines. It addresses design, materials, manufacturing, and testing requirements.
How to Apply API 17J-2014
Conformity work starts by confirming the exact edition of API 17J-2014 required by the contract and identifying any purchaser-specific additions. The product type, material system, dimensions, pressure or temperature rating, manufacturing route, and intended service environment must then be mapped to the clauses that apply. An inspection and test plan should state the sampling frequency, specimen conditioning, calibrated equipment, acceptance criteria, witness points, and rules for retesting before laboratory work begins.
A defensible report records sample identity, batch traceability, the method and edition used, environmental conditions, raw observations, calculations, measurement uncertainty where relevant, deviations, and the final result against each requirement. LEISA uses this evidence chain to help buyers, manufacturers, and engineering companies distinguish a repeatable compliance decision from a simple pass/fail statement. The original publication remains the controlling source whenever a summary conflicts with the standard text.
