制造与质量保证
盐山恒臻园管道 — 集成成型、热处理、机加工与无损检测，服务出口公用工程与 EPC 项目。
制造能力
- Forged ASTM A105 / A105N bodies for Class 300 service
- CNC machining of hub, bore and RF facing per ASME B16.5
- Higher hub thickness than Class 150 for elevated pressure rating
- Long weld neck and reducing bores from approved drawings
检验与放行
- OD, PCD, bore and hub length vs B16.5 Class 300 tables
- PMI and hardness survey when ITP requires
- MT on forged surfaces; UT per Section V when specified
- Third-party witness and hydro documentation for packages
工程常见问题
Use the piping pressure–temperature rating per ASME B16.5. Class 300 flanges suit higher design pressures within the A105 material group limits.
No. Bolt circle, flange OD, hub dimensions and ratings differ by class. Always match class on the line list.
Many EPC specs require normalized A105N for improved toughness. State grade on the purchase order.
Yes. Heat analysis and mechanical results per batch; PMI retests per ITP when required.
