Qib Steel
GB / T 3087 seamless boiler raj feem ntau tsim nyob rau hauv ob qib:
10#: Qib no paub txog nws cov machinability zoo heev thiab weldability, ua rau nws haum rau ntau yam kev siv uas yuav tsum tau ua thiab vuam.
20#: Muab lub zog ntau dua piv rau 10#, ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau ua kom zoo dua qub.
Daim ntawv thov
GB / T 3087 seamless boiler raj yog dav siv hauv:
Boiler Manufacturing: Qhov tseem ceeb rau kev tsim cov qis thiab nruab nrab -siab boilers.
Thaum tshav kub kub Exchangers: Siv nyob rau hauv tshav kub exchanger systems vim lawv zoo heev thermal conductivity.
Kev lag luam Petrochemical: Siv nyob rau hauv ntau yam petrochemical cov txheej txheem uas kub kuj tseem ceeb heev.
Fais fab nroj tsuag: Ib qho tseem ceeb hauv lub tshuab hluav taws xob tsim hluav taws xob rau kev hloov hluav taws xob zoo.
