GB/T5310-2008Seamless zitsulo chubu ndi mtundu wapamwamba zitsulo chubu.Boiler chubu imagawidwa mu chubu cha boiler wamba komanso chubu cha boiler chothamanga kwambiri malinga ndi kutentha kwake.Chitoliro chopopera chopondera kwambiri chimagwiritsidwa ntchito kwambiri popanga ma boilers othamanga komanso opitilira muyeso, mapaipi ndi zitsulo zina zapamwamba kwambiri za carbon structural steel, alloy structural chitsulo ndi chitoliro chosapanga dzimbiri chosagwira chitsulo chosapanga dzimbiri.[1] Machubu otenthetserawa amagwira ntchito pakutentha kwambiri komanso kupanikizika, kutulutsa mpweya wotentha kwambiri komanso mpweya wamadzi, womwe umakonda kukhala ndi okosijeni komanso dzimbiri.

Gulu lachitsulo

(1) Mkulu khalidwe mpweya structural zitsulo 20G, 20MnG, 25MnG. 

(2) Aloyi dongosolo zitsulo 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc. 

(3) Dzimbiri kutentha zosagwira zitsulo ambiri ntchito 1Cr18Ni9, 1Cr18Ni11Nb kukatentha chubu kuwonjezera kuonetsetsa mankhwala zikuchokera ndi katundu makina, kuchita madzi kuthamanga mayeso, kupanga flaring, psinjika mayeso.Machubu achitsulo amaperekedwa m'malo ochizira kutentha. 

Kuphatikiza apo, microstructure, kukula kwa tirigu ndi decarburization wosanjikiza wa machubu omalizidwa achitsulo amafunikiranso.

Kuphatikiza pa boiler yothamanga kwambiri yopanda chitsulo chubuGB/T5310-2008zomwe tazitchula pamwambapa, zinthu zazikulu za kampani yathu ndi:

ASTMA210(A10M)-2012Chitoliro chachitsulo chapakati cha carbon ndi chitoliro chachitsulo chosasunthika, chinthu chachikulu ndi SA210 GrA1,SA210GrC;

ASME SA106/SA-106M-2015, zida zazikulu ndi GR.B gr.C;

ASME SA-213/SA-213M, wamba aloyi zakuthupi: T11, T12, T22 ndi T23, T91, P92, T5, T5b, T9, T21, T22, T17;

ASTM A335 / A335M - 2018, zipangizo zazikulu ndi: P11, P12, P22, P5, P9, P23, P91, P92, P2, etc.
