1. Cov kav dej seamless carbon steel puas siv tau los thauj dej, roj, thiab roj?
kiag li.
Seamless kav raws li GB / T 8163, ASTM A53, A106, thiab API 5L yog tsim tshwj xeeb rau kev thauj cov kua dej xws li dej, roj, roj, nkev, thiab cua compressed. Ntev npaum li cov khoom siv, siab, thiab phab ntsa thickness sib xws, lawv muaj kev nyab xeeb thiab txhim khu kev qha.
2. Dab tsi yog qhov kub ntawm seamless carbon steel kav?
Ordinary 10 #, 20 #, thiab A106B seamless kav:
Ntev -lub sijhawm ua haujlwm kub: -20℃~ 450 degree
Luv -lub sij hawm ua haujlwm kub: Siab dua
Rau qhov kub siab tshaj qhov txwv no, cov kav hlau alloy steel lossis boiler - cov kav dej tshwj xeeb raug pom zoo. Rau qhov qis- qhov kub thiab txias, qis- kub cuam tshuam steels xws li Q355C / D thiab A333 series tuaj yeem siv.
3. Dab tsi siab tuaj yeem seamless carbon steel kav?
Siab tsis kam nyob ntawm:
Khoom siv
Sab nraud txoj kab uas hla
Phab ntsa thickness
Kub
Vuam thiab kev ua haujlwm. Cov qauv tsim siab tuaj yeem suav nrog cov qauv Barlow. Peb tuaj yeem suav cov phab ntsa tuab uas tsim nyog pub dawb raws li tus neeg siv khoom ua haujlwm.
4. Koj puas tuaj yeem muab kev pabcuam txiav, beveling, threading, thiab chamfering?
Yog lawm. Peb muab ib qho - nres cov kev pabcuam:
Txiav rau qhov ntev
Beveling (ib zaug -sab beveling, ob -sided beveling)
Threading (cov yeeb nkab xov, NPT, BSP, BG, thiab lwm yam)
Chamfering, kawg xov, polishing
Painting, bundling, labeling
Kev xa ncaj qha mus rau qhov chaw tsim kho rau kev teeb tsa.
5. Seamless carbon steel kav yuav galvanized?
Yog lawm. Cov kav dej tsis muaj seamless tuaj yeem yog kub-dip galvanized lossis electro-galvanized los txhim kho xeb thiab corrosion kuj, thiab yog dav siv nyob rau hauv sab nraum zoov, tiv thaiv hluav taws, dej, thiab roj pipelines. Galvanizing ua rau muaj kev zoo nkauj zoo nkauj thiab lub neej ntev dua, tab sis nws nce nqi.
