DIN 17175 Seamless Steel Yeeb Nkab
Lub ntsiab lus tseem ceeb
A German txujrau seamless steel raj thiab cov kav dej tsim los siv ntawmsiab kub, feem ntau hauvfais fab nroj tsuag, boilers, thiab tshav kub exchangers. Nws tsom mus rau lub sijhawm ntev - lub zog thiab nkag mus rau hauv qab cua sov.
Lub npe piav qhia
| Ib feem | Lub ntsiab lus |
|---|---|
| DIN | Lub koom haum German rau Standardization |
| 17175 | Txheem rau seamless raj ntawm tshav kub-resistant steels |
| Seamless | Tsis muaj longitudinal weld seam |
| Ntsiab tsom | Siab -kev pabcuam kub |
Ntsiab nta & Qib
| Feature | Kev piav qhia |
|---|---|

Cov lus sib piv: DIN 17175 vs. DIN 1629
| Yam | TIAB SA 17175 | TIAB SA 1629 |
|---|---|---|
| Lub Hom Phiaj | Siab -kev pabcuam kub(cov nroj tsuag muaj zog) | General engineering / siab |
| Cov khoom tseem ceeb | Creep rupture zog | Tensile/yield zog ntawm chav tsev kub |
| Khoom siv | Tsawg- alloy, tshav kub- cov hlau tsis muaj zog | Cov hlau tsis muaj hlau tsis zoo |
| Kev siv yam | Superheater tubes, chav headers | Hydraulic systems, boilers (qis temp) |
| Kuaj tsom | High -kub tensile, creep tests | Chav- ntsuas kub |
Cov ntawv thov siv
Fais fab nroj tsuag boilers(superheaters, reheater raj, headers)
Siab -cov kav dej siab
Thaum tshav kub kub exchangers nyob rau hauv chemical / petrochemical nroj tsuag
High -kub piping nyob rau hauv industrial furnaces
Cheebtsam rau nuclear fais fab kev teeb tsa (cov qib tshwj xeeb)
Piv txwv Qib Ntsiab: 15Mo3
Kev siv yam:Boiler superheater tubes
Ntsiab Alloy:~ 0.3% Molybdenum
Feature:Zoo creep zog mus txog ~ 500 ° C
Nco tseg:DIN 17175 tau dhau los ua ntau dua los ntawm European tus qauvTS EN 10216-2(Cov raj tsis muaj seamless rau lub hom phiaj siab - Ntu 2), tab sis cov npe DIN thiab qib npe (xws li 13CrMo4-5) tseem muaj ntau hauv cov kev qhia tshwj xeeb thiab kev lag luam siv.
