daim ntawv thov
Cov nkoj siab:
Kev siv ntau tshaj plaws, kom muaj cov kua dej thiab cov pa roj hauv siab, suav nrog cov khoom siv hauv petrochemical thiab tshuaj ua haujlwm. Nws yog dav teev rau reactors, separators, thiab lwm yam khoom siv tseem ceeb uas txhim khu kev qha kev ua tau zoo nyob rau hauv kev kub siab thiab kub cycling yog qhov tseem ceeb.
Boilers & Kub Exchangers:
Qhov zoo tshaj plaws rau kev tsim hluav taws xob thiab kev lag luam cua sov vim nws thermal stability thiab weldability. Nws yog siv nyob rau hauv boiler nruas, headers, thiab tshav kub exchanger tubesheets, qhov twg nws yuav tsum tau tiv taus siab kub thiab rov qab thermal stress.
Cia Tank:
Siv los khaws cov kua dej ntawm qhov kub nruab nrab, suav nrog API 650/620 tso tsheb hlau luam. Nws txoj kev weldability zoo thiab tsis kam rau cov pob txha tawg ua rau nws haum rau loj - ntim cov roj crude, cov khoom ua kom zoo, thiab tshuaj lom neeg.
Piping & Compressors:
Cheebtsam rau pressurized systems. Nws yog ua hauj lwm nyob rau hauv siab - cov kav dej thiab compressor qhov chaw uas yuav tsum tau muaj zog thiab toughness nyob rau hauv tas li ntawd mus ua hauj lwm.
Kev tsim kho:
Cov qauv tubing, cov qauv teeb pom kev zoo, cov ncej sib kis, thiab cov khoom siv rau cov khoom hnyav. Nws cov khoom sib npaug ua rau nws tus nqi - kev xaiv zoo rau cov qauv siv uas yuav tsum tau ua kom ntev.
Kev thauj mus los:
Automotive thiab tsheb thauj khoom, tsheb ciav hlau, thiab cov thawv ntim khoom. Nws muab lub zog tsim nyog thiab tsim nyog rau hnyav - cov khoom siv thauj mus los, ua kom lub neej ua haujlwm ntev nyob rau hauv cov xwm txheej hnyav.

Qhov txawv ntawm A36 thiab A516-70 yog dab tsi?
ASTM A516 GR 70 ua tau zoo tshaj ASTM A36 hauv lub zog tensile, qis-kub toughness, thiab siab lub nkoj siv, thaum A36 zoo dua rau kev siv cov qauv siv.
Dab tsi welding pas nrig rau A516 qib 70?
Rau vuam ASTM A516 Qib 70 steel, ntau thiab pom zoo vuam rods (electrodes/filler hlau) muaj xws li E7018 (rau SMAW), ER70S-6 (rau GMAW), thiab E71T-1C (rau FCAW), raws li lawv phim cov khoom siv lub zog thiab kev siv dej tsawg-tso rau cov khoom siv hluav taws xob tsawg thiab cov khoom siv hluav taws xob tsawg. input kom tau zoo tshaj plaws.
