ASTM A500 Steel Qauv Tubing piav qhia
ASTM A500 qauv raj xa mus rau txias- ua welded thiab seamless carbon steel structural raj siv nyob rau hauv engineering lug, ua raws li tus qauv specification ASTM A500. Nov yog cov lus piav qhia ntxaws ntxiv:
Txhais thiab Standard Compliance
Nws yog ib hom steel raj tshwj xeeb tsim rau kev siv cov qauv. ASTM A500 tus qauv teeb tsa cov kev xav tau rau cov raj zoo li no, suav nrog nws cov khoom siv, cov txheej txheem tsim khoom, cov txheej txheem kuaj, thiab qhov ntev ntev.
Kev tsim khoom
Txias-Kev tsim: Lub raj yog tsim los ntawm bending steel strips los yog coils ntawm chav tsev kub rau hauv cov duab uas xav tau, xws li puag ncig, square, lossis duab plaub. Cov txheej txheem no txhim kho lub zog thiab qhov tseeb ntawm lub raj.
Welded los yog Seamless: ASTM A500 raj tuaj yeem yog welded lossis seamless. Welded tubes yog tsim los ntawm kev koom nrog cov npoo ntawm cov hlua hlau los ntawm kev vuam, thaum cov hlab seamless yog tsim los ntawm cov khoom siv hlau tsis muaj vuam seams.
Khoom Khoom
Tshuaj muaj pes tsawg leeg: Tus qauv qhia qhov siab tshaj plaws thiab qhov tsawg kawg nkaus txwv rau ntau yam hauv cov hlau, xws li carbon, manganese, phosphorus, thiab sulfur, kom ntseeg tau tias cov khoom siv kho mob xav tau.
