A192 seamless carbon steel boiler raj rau siab -pressure service Description
A192 siab-kub kub yog seamless carbon steel raj tshwj xeeb tsim los rau siab - kub thiab siab - siab boiler ib puag ncig. Ua raws li American ASTM A192 tus qauv, lawv muaj lub zog zoo dua, ruaj khov, thiab ua haujlwm tau zoo nyob rau hauv siab - qhov kub thiab txias ua tsaug rau lawv cov khoom siv thiab cov txheej txheem tsim khoom zoo. Cov yam ntxwv tseem ceeb:
Lub hauv paus ntawm cov khoom siv: Raws li cov pa roj carbon steel, kev tswj xyuas cov tshuaj muaj pes tsawg leeg (xws li cov ntsiab lus ntawm cov pa roj carbon thiab manganese) thiab cov txheej txheem kho cua sov kom ntseeg tau tias cov raj steel tuav cov qauv siv lead ua ruaj khov ntawm qhov kub thiab txias. Qhov kev tsim no ua rau nws tsis tshua muaj kev cuam tshuam rau cov txheej txheem degradation, xws li grain ciam corrosion los yog embrittlement, nyob rau hauv ntev - lub sij hawm siab - kub raug.
Cov txheej txheem tsim khoom: Cov raj seamless yog tsim los siv cov txheej txheem kub dov los yog txias kos duab. Kub dov yog tsim rau huab hwm coj ntau lawm, xyuas kom meej efficiency; txias daim duab ntxiv txhim kho qhov tseeb qhov tseeb thiab qhov chaw tiav, ua tau raws li qhov yuav tsum tau ua ntawm kev sib dhos precision.

Daim ntawv thov
Boiler Core Cheebtsam: dav siv nyob rau hauv cov cua kub nto raj ntawm siab - siab thiab siab tshaj dej siab - raj boilers, xws li economizers (preheating boiler feedwater los txhim kho thermal efficiency), superheaters (cua sov saturated chav rau superheated chav), thiab reheaters (txhim kho lub chav ua hauj lwm muaj peev xwm). Cov khoom no tuaj rau hauv kev sib cuag ncaj qha nrog siab - kub, siab - dej siab los yog chav dej, thiab lub siab - qhov kub thiab txias thiab corrosion kuj ntawm A192 raj yog ib qho zoo meej match.
Industrial High-Temperature Equipment: Nyob rau hauv cov xwm txheej xws li tshuaj reactors thiab roj av refining cov khoom uas siab -kub, siab - cov kua siab yuav tsum tau thauj, A192 raj yog ib qho tseem ceeb piping khoom, kom muaj kev ruaj ntseg thiab efficiency ntawm cov kua kis tau tus mob.
Kev kuaj thiab tshuaj xyuas
Flattening Test
Txhua batch yuav tsum muaj ob qhov kawg ntawm ob lub kav dej raug rau kev sim ua kom tiaj tus, nrog rau txoj kev sim tom qab ASTM A450, Division 19.
Flaring Test
Txhua lub batch yuav tsum muaj ob qhov kawg ntawm ob lub kav dej uas raug rau kev sim ua kom flattening, nrog rau txoj kev sim ua raws li ASTM A450, Division 21. Cov raj no yuav tsum raug xaiv sib nrug los ntawm cov siv rau kev sim flattening.
