DIN17175 siab- siab seamless steel raj yog ib hom seamless steel khoom, nrog rau lus Askiv lub npe "High siab seamless steel raj." Nws muaj lub zog nkag siab, oxidation tsis kam, thiab microstructural stability, thiab feem ntau yog siv los tsim cov khoom xws li superheater tubes thiab cov kav dej rau siab - siab boilers.
DIN17175 yog ib hom seamless raj rau siab -siab boilers. Txoj kev tsim khoom yog tib yam li cov kav dej seamless, tab sis muaj cov kev cai nruj rau cov hom hlau siv hauv lawv cov khoom. Raws li kev ua haujlwm kub, lawv tau muab faib ua ob pawg: cov raj boiler dav dav thiab siab - siab boiler raj.
Manufacturing Methods:
- General boiler raj yog siv nyob rau hauv kub qis dua 450℃thiab feem ntau yog ua los ntawm carbon structural steel los ntawm kub - dov los yog txias - txheej txheem kos duab.
- High-siab boiler seamless raj feem ntau raug rau qhov kub thiab txias. Nyob rau hauv cov teebmeem ntawm siab -kub flue roj thiab ncu, lawv muaj oxidation thiab corrosion. Yog li ntawd, cov raj no yuav tsum muaj lub zog nkag siab, zoo heev oxidation thiab corrosion kuj, thiab zoo microstructural stability.
Daim ntawv thov:
- General boiler hlab yog tsuas yog siv los tsim cov phab ntsa hauv dej, cov raj dej kub, cov raj dej ua kom sov, cov kav dej superheated rau locomotive boilers, cov raj loj thiab me me, thiab cov hlab cib.
- High-siab boiler seamless raj feem ntau yog siv los tsim superheater tubes, reheater tubes, coj cov raj, thiab lub ntsiab chav boilers rau siab thiab ultra- kub siab boilers.

Kev kuaj thiab tshuaj xyuas
Kev tshuaj xyuas zoo ntawm DIN17175 siab-siab seamless boiler raj feem ntau suav nrog tshuaj lom neeg tshuaj ntsuam xyuas, kuaj cov cuab yeej siv tshuab, kuaj cov qauv metallographic, ntsuas qhov ntsuas qhov ntsuas, ntsuas qhov zoo ntawm qhov chaw, thiab tsis yog- kuaj kev puas tsuaj kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab nyob rau hauv siab - kub thiab siab siab {{4}.
