Steel for Oil, Gas, and Pipeline Projects
Oil and gas steel procurement begins with fluid composition, pressure, temperature, fracture control, sour-service risk, corrosion management, joining, inspection, and the governing piping or pipeline code.
首先确认
整个项目不存在一份通用的金属材料规范
应先把项目拆分为不同系统，记录各自服役环境和适用规范，再选择相互兼容的材料、产品标准、加工路线、防护体系与检验计划。
Dry gas, wet gas, crude, refined products, water injection, chemicals, and multiphase service
Internal pressure, cyclic operation, temperature extremes, fracture-control, and geohazard loads
CO2, H2S, chlorides, microbiological activity, external soil or marine exposure, and under-insulation conditions

项目控制
标准、认证与文件
- Applicable ASME B31 pipeline or process-piping code and project piping classes
- API line pipe, tank, pressure-equipment, and inspection standards as applicable
- Design basis, fluid composition, corrosion study, materials selection report, and line list
- Welding procedures, qualification records, NDE plan, pressure-test package, and coating specification
- Material certificates, supplementary-test results, traceability, and manufacturing record book
制造与物流
需要控制的供货接口
- 制造图、焊接、热处理、涂层与修补程序
- 检验见证点、试验方法、验收准则与文件批准
- 下料和组装全程标识、防护、包装与集运
- 目的地要求、现场储存、安装接口与交付顺序
风险清单
常见采购风险
Omitting sour-service, fracture-control, low-temperature, or supplementary-test requirements from the purchase order
Treating pipe, fittings, flanges, bolting, weld metal, and coating as unrelated purchases
Accepting grade substitutions without code, wall-thickness, toughness, weldability, and corrosion review
Loss of traceability or inconsistent document requirements across mills, fabricators, and package vendors
