ASTM A537 chitsulo

Mafotokozedwe a ASTM A537 amakwirira mbale zazitsulo za kaboni zotenthetsera pamakina okakamiza.
Ma mbale a ASTM A537 Class 1 amaperekedwa m'malo okhazikika pomwe mbale za Class 2 zimazimitsidwa ndikupsya mtima. Ma plates a ASTM A537 a carbon steel amalimbikitsa kukhazikika komanso kutulutsa mphamvu kuposa mbale zopatsirana zomwe zimaperekedwa pansi pa ASTM A516 standard.
Gnee Steel amagwira ntchito mwapadera popereka ma plates amphamvu omwe nthawi zambiri amafunikira makampani a Mafuta, Gasi ndi petrochemical. Timapereka zakuthupi ku ASTM A537 mu makulidwe angapo ndi makulidwe kuti zigwirizane ndi zomwe mukufuna.
Gawo la ASTM A537
Ma plates a ASTM A537 Class 1 azitsulo amapangidwa kuti azigwiritsidwa ntchito popanga zotengera zokakamiza.
Chitsulocho ndi chitsulo chokhazikika chomwe chimagwiritsidwa ntchito kutentha ndipo chifukwa chake chimawonetsa zokolola zambiri komanso mphamvu zolimba kuposa magiredi a ASTM A516. Chitsulochi ndi chabwino kwambiri kuti chizigwiritsidwa ntchito popanga ma boilers ndi zotengera zopanikizika ndipo Gnee Steel imapereka mbale za A537 Class 1 kwa akatswiri otsogola padziko lonse lapansi opanga zinthu zopangidwa ndi mafuta, Gasi ndi Petrochemical.
Titha kupereka mbale za ASTM A537 Class 1 kuchokera kumasheya kapena mwachindunji kuchokera pamphero. Timaperekanso ntchito yowonera m'nyumba momwe zinthu zimatha kudulidwa kukula kapena mawonekedwe omwe mukufuna.

Chitsulo cha ASTM A537 Class 2 ndi chokolola chambiri komanso cholimba champhamvu chomwe chimagwiritsidwa ntchito popanga zombo zoponderezedwa ndi ma boiler achitsulo.
Chitsulochi chimaphatikizapo kuphatikizika kwa kaboni, manganese ndi silicon ndipo chimatenthedwa pogwiritsa ntchito njira yozimitsidwa ndi kupsya mtima yomwe imapatsa zidazo mphamvu zotsalira. Pothandizidwa ndi opanga opanga otsogola padziko lonse lapansi, ASTM A537 Class 2 ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi mafakitale amafuta, gasi ndi petrochemical.
Gnee Steel ipereka mbale za ASTM A537 Class 2 kuchokera ku katundu kapena mwachindunji kuchokera ku chigayo. Timaperekanso ntchito zodulira zitsulo kuphatikiza kudula kwamoto wa CAD kuti mudule zitsulo zanu m'mawonekedwe apadera.
