Tuam Tshoj Sch40 A53 A106 API 5L Seamless thiab Welded Carbon Steel Yeeb Nkab
Txheej txheem cej luam
"Sincerity, Innovation, Rigorousness, and Efficiency" tuaj yeem yog qhov kev xav tsis tu ncua ntawm peb lub koom haum, rau lub sijhawm ntev mus rau kev sib raug zoo, Tam sim no, lub npe ruaj khov muaj carbon steel thiab Cr Mo Alloy Steel cov khoom thiab tau txais cov ntaub ntawv zoo tshaj plaws thiab cov khoom loj. nyob rau hauv kev ua lag luam tso domestic thiab txawv teb chaws.
Ib qho ntawm kev siv peb cov kav dej yog hluav taws ua haujlwm, xws li kev thauj mus los hauv dej rau kev ua haujlwm tua hluav taws, kev tiv thaiv hluav taws xob rau hluav taws kub wrk system thiab lwm yam.
Thov nco ntsoov, cov kav dej hlau, cov kav tooj liab, cov kav hlau alloy, cov kav dej sib txuas, cov yeeb nkab carbon steel, thiab lwm yam yog feem ntau siv rau cov kav dej tua hluav taws. Cov kev xav tau loj yog txawv ntawm cov kav dej dav dav thiab muaj lawv tus kheej cov kev cai tshwj xeeb. Cov kav dej tua hluav taws feem ntau yuav tsum tau pleev xim rau xim liab lossis lub voj voog liab. Yuav kom paub qhov txawv ntawm lwm cov kav dej.
Hauv kev ua haujlwm tiag tiag, qhov sib txawv ntawm kev tiv thaiv hluav taws muaj qhov sib txawv ntawm cov yeeb nkab hom thiab cov khoom siv, xws li: cov kav dej siv hluav taws xob hauv cov kav hluav taws hauv tsev, thaum lub zog ua haujlwm siab tsawg dua lossis sib npaug ntawm 1.20MPa, kub-dip galvanized steel kav. tuaj yeem siv tau; Thaum lub siab ua hauj lwm siab tshaj 1.20MPa, kub-dip galvanized thickened steel yeeb nkab los yog kub-dip galvanized seamless steel yeeb nkab yuav tsum tau siv; Thaum lub zog ua haujlwm siab tshaj 1.60MPa, kub-dip galvanized seamless steel yeeb nkab yuav tsum tau siv.
Daim ntawv thov
Seamless steel yeeb nkab rau kev ua haujlwm kub ASTM A106, haum rau qhov kub thiab txias
