Comparable International References
| Reference family | How buyers use it | Quotation note |
|---|---|---|
| API Spec 5L / ISO 3183 | Line pipe reference when the welded pipe is ordered for oil, gas, or water transmission. | Confirm PSL, grade, pipe body route, weld NDT, hydrotest, and coating. |
| ASTM A252 / EN 10219 by application | Comparison families used when the same welded route is ordered for piling or structural work. | Application decides the controlling standard. |
| SSAW / LSAW project data sheet | Manufacturing route, weld inspection, bevel, coating, lining, and length are normally project-controlled. | Do not quote only by process name. |
Grade and standard references are for procurement comparison only. They are not direct substitutions unless the buyer specification, design code, and engineering review approve the change.
