DIN 1629 Seamless Steel Yeeb Nkab
Lub ntsiab lus tseem ceeb
A German industrial standardrau seamless ncig steel kav siv raucov hom phiaj engineering. Tsis zoo li API 5L, nws yogtsis yog tshwj xeeb rau cov kav dej roj / roj.

Cov lus sib piv: DIN 1629 vs API 5L
| Yam | TIAB SA 1629 | API 5L (piv txwv li, X70) |
|---|---|---|
| Lub Hom Phiaj | General engineering, boilers | Roj & roj pipelines |
| Qib | Txoj Kev 37.0, Txoj Kev 44.0, Txoj Kev 52.0 | X42, X52, X70, X80, thiab lwm yam. |
| Lub zog | Nruab nrab (piv txwv li, St.52.0: Min 355 MPa tawm los) | Siab heev (piv txwv li, X70: 483 MPa tawm los) |
| Qhov yuav tsum tau muaj | Tensile zog, ductility | Yield zog, toughness, H₂S kuj |
| Kev Ua Lag Luam | Teb chaws Europe, kev lag luam dav dav | Kev lag luam roj & roj thoob ntiaj teb |
Cov ntawv thov siv
Mechanical engineering structures
Hydraulic thiab pneumatic thooj voos kheej kheej
Tsawg mus rau nruab nrab - cov kua dej siab
Automotive thiab machinery qhov chaw
Boiler thiab cua kub exchanger raj (nyob rau hauv cov kev txwv)
Nco tseg:DIN 1629 feem ntau tau hloov pauv los ntawm EuropeanTS EN 10297-1tus qauv rau seamless mechanical raj, tab sis lub npe tseem siv dav hauv kev lag luam specifications.
