Yonke imibhobho ye-carbon steel esetyenziswe kumaqondo aphantsi (ngaphantsi kwe-20 ° C) kufuneka yamkele umgangatho we-GB6479, ochaza kuphela iimfuno zefuthe eliphantsi lobushushu bezinto eziphathekayo.

GB3087kwayeGB5310imigangatho yimigangatho emiselwe ngokukodwa kwibhoyila yentsimbi yemibhobho. "Imigaqo yoKhuseleko loKhuseleko lweBoiler" igxininisa ukuba zonke iibhobho eziqhagamshelwe kwiibhoyili zingaphakathi kwendawo yokulawula, kwaye ukusetyenziswa kwezixhobo zabo kunye nemigangatho kufuneka ihambelane "neMimiselo yokuPhathwa koKhuseleko lweBhola". Ngoko ke, iibhoyili, izityalo zamandla, ukufudumeza kunye nezixhobo zokuvelisa i-petrochemical zisebenzisa Imibhobho yomphunga kawonkewonke (enikezelwe yinkqubo) kufuneka ithathe imigangatho ye-GB3087 okanye i-GB5310.

Kuyafaneleka ukuba uqaphele ukuba ixabiso lemibhobho yensimbi enemigangatho emihle yemibhobho yentsimbi nayo iphezulu kakhulu. Ngokomzekelo, ixabiso le-GB9948 liphantse libe yi-1/5 ephezulu kunelo lezinto ze-GB8163. Ngoko ke, xa ukhetha imigangatho yempahla yombhobho wensimbi, kufuneka iqwalaselwe ngokubanzi ngokwemiqathango yokusetyenziswa. Imele ithembeke kwaye ithembeke. Ukuba noqoqosho. Kufuneka kwakhona kuqatshelwe ukuba iipayipi zensimbi ngokwe-GB/T20801 kunye ne-TSGD0001, i-GB3087 kunye nemigangatho ye-GB8163 ayiyi kusetyenziselwa imibhobho ye-GC1 (ngaphandle kokuba i-ultrasonically, umgangatho awukho ngaphantsi kwenqanaba le-L2.5, kwaye ingasetyenziselwa i-GC1 ngokuyila uxinzelelo olungekho ngaphezulu kwe-4.0Mpa (1) yombhobho).
