A53 Welded Tube
A53 npog seamless thiab welded, dub thiab kub-dip galvanized nominal (nruab nrab) phab ntsa yeeb nkab rau coiling, dabtsi yog khoov, flanging thiab lwm yam tshwj xeeb lub hom phiaj haum rau vuam. Nruam welded yeeb nkab tsis haum rau flanging. Lub hom phiaj ntawm cov yeeb nkab yuav tsum tau teev nyob rau hauv qhov kev txiav txim.
ASTM A53 steel yeeb nkab yog dav siv hauv kev tsim kho thiab kev thauj mus los hauv av.
Piv txwv li: nws tuaj yeem siv los ua cov kav dej ua kua los tso dej tawm hauv av. Nws yog siv los ua lub raj xa dej rau kev thauj mus los rau roj thiab roj thiab hauv cov chaw nres tsheb fais fab. Nws kuj tseem siv los ua cov qauv hlau rau cov khoom siv kho tshuab. Tom qab txheej nrog zinc, nws tuaj yeem siv rau hauv cov nroj tsuag cua.
