High-pressure boiler raj yog ib hom boiler raj, teej tug mus rau qeb ntawm seamless steel raj. Txoj kev tsim khoom yog tib yam li cov raj seamless, tab sis muaj cov kev cai nruj ntawm cov hlau siv los tsim cov raj steel. High-pressure boiler raj yog tsuas yog siv los tsim superheater raj, reheater raj, roj qhia raj, lub ntsiab chav boilers, thiab lwm yam.

Cov qib steel siv yog: high-zoo carbon structural steel qib yog 20G, 20MnG, 25MnG;
Alloy structural steel qib yog 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, thiab lwm yam;
Xwb-resistant kub-resistant steel feem ntau siv 1Cr18Ni9, 1Cr18Ni11Nb high-pressure boiler hlab;
Ntxiv nrog rau kev ua kom ntseeg tau cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab, kev ntsuas dej siab yuav tsum tau ua ntawm txhua lub raj, thiab kev nthuav dav thiab kev sib tw yuav tsum tau ua. Cov yeeb nkab steel yog xa mus rau hauv lub xeev kub-kho. Tsis tas li ntawd, muaj qee qhov yuav tsum tau ua rau microstructure, grain loj, thiab decarburized txheej ntawm cov yeeb nkab steel tiav.
