Txheej txheem cej luam ntawm A179 thiab GB 5310
A179 thiab GB 5310 yog seamless steel raj specifications nrog ntau lub hom phiaj thiab lub hauv paus hauv cheeb tsam. ASTM A179/A179M npog seamless txias-tso qis- cov pa roj carbon steel raj rau cov khoom siv hluav taws xob sib hloov, condensers thiab cov khoom siv hluav taws xob zoo sib xws. GB 5310 yog Suav lub teb chaws tus qauv rau seamless steel raj siv nyob rau hauv siab -siab boilers, npog carbon steel thiab qis- alloy steel qib. Ob qho qauv no feem ntau tau hais ua ke hauv cov haujlwm uas xav tau ob qho tib si boiler thiab kub exchanger tubing, tab sis lawv tsis hloov pauv.

Qib Systems thiab Khoom siv
A179 txhais ib qho qis- carbon hlau muaj pes tsawg leeg nrog carbon 0.06-0.18% thiab manganese 0.27-0.63%, optimized rau ductility, raj dov thiab vuam. GB 5310 txhais ntau qib rau cov kev pabcuam kub sib txawv: carbon steels xws li 20G rau nruab nrab qhov kub thiab txias, thiab Cr-Mo lossis Cr-Mo-V alloy steels xws li 15CrMoG thiab 12Cr1MoVG rau qhov kub siab dua thiab kev pabcuam creep-resistant. Qib kev xaiv hauv GB 5310 nyob ntawm qhov tsim kub thiab siab.
Kev tsim khoom thiab kev sim
A179 raj yog txias los ntawm seamless hollows kom ua tiav qhov ntev thiab du nto, ces annealed thiab sim rau tensile zog, flattening, flaring thiab siab ncaj ncees. GB 5310 boiler tubes yog kub tiav los yog txias kos, raug rau normalizing los yog lwm yam kev kho cua sov, thiab xyuas los ntawm kev tshuaj ntsuam xyuas, tensile thiab cuam tshuam kev ntsuam xyuas, hydrostatic los yog nondestructive kuaj, thiab nto thiab seem soj ntsuam. Cov kev sim thiab cov ntaub ntawv yuav tsum tau muaj feem ntau xav tau rau cov raj boiler vim yog cov kev pabcuam hnyav.
Daim ntawv thov
A179 raj tau nruab rau hauv lub plhaub- thiab- raj kub exchangers, condensers thiab coolers nyob rau hauv refineries, fais fab nroj tsuag thiab cov txheej txheem cov nroj tsuag. GB 5310 raj yog siv rau hauv boiler dej-phab ntsa, superheater, reheater thiab lub ntsiab chav tsev, nrog rau nyob rau hauv siab -kub chav pipelines. Ib qhov project yuav xav tau ob qho tib si: A179 rau cov khoom siv hluav taws xob sib pauv thiab GB 5310 rau qhov chaw boiler siab.
Yuav xaiv li cas
Xaiv los ntawm cov khoom muaj nuj nqi: siv A179 / SA-179 rau cov cua kub exchanger thiab condenser raj, thiab GB 5310 rau boiler thiab high-pressure steam tubes. Kuj tseem xav txog txoj cai tswj hwm ntawm qhov project, qhov ntsuas kub tsim, thiab cov ntaub ntawv tshuaj xyuas yuav tsum tau ua. Paub meej tias qib pes tsawg, qhov loj me, kev kho cua sov thiab kev xeem yuav tsum tau ua nrog tus xa khoom tubing ua ntej xaj.
FAQ Txog A179 thiab GB 5310
A179 raj puas siv tau rau hauv lub boiler?
Tsis yog rau siab -siab boiler siab qhov chaw. A179 yog tsim los rau cov kev pab cuam cua sov, tsis yog rau boiler chav tsim lub luag haujlwm; boiler raj yuav tsum ua raws li cov qauv xws li GB 5310 los yog ib tug sib npaug boiler raj qauv.
Puas yog GB 5310 tsuas yog rau carbon steel?
Tsis yog GB 5310 npog ob qib carbon steel xws li 20G thiab alloy steel qib xws li 15CrMoG thiab 12Cr1MoVG.
Dab tsi yog qhov txawv ntawm ob tus qauv?
Qhov sib txawv tseem ceeb yog lub hom phiaj: A179 yog cov khoom siv hluav taws xob sib txuas hluav taws xob, thaum GB 5310 yog lub boiler tube specification rau siab -siab qhov kev pab cuam nrog cov qib sib txawv thiab xav tau ntau dua kev sim.
Puas yog GB 5310 siv tib qib qib raws li A179?
No. A179 siv ib qho ASTM muaj pes tsawg leeg; GB 5310 siv Suav qib kev xaiv xws li 20G thiab 12Cr1MoVG.
Tus qauv twg yuav tsum tau siv rau lub raj superheater?
Rau kev pab cuam superheater thiab reheater, siv lub boiler raj qauv xws li GB 5310 (piv txwv li 15CrMoG los yog 12Cr1MoVG) los yog sib npaug thoob ntiaj teb boiler raj qauv xav tau los ntawm qhov project.
Ob hom tubing puas tuaj yeem welded ua ke?
Yog lawm, nrog rau cov txheej txheem vuam kom raug, vim ob leeg yog cov pa roj carbon lossis tsawg- alloy steels; muab tub lim hlau thiab preheat yuav tsum raug xaiv rau qib siab dua - zog.
