Cov kav hlau tuaj yeem muab faib ua ob pawg raws li kev tsim khoom: seamless steel kav thiab welded steel kav. Welded steel kav yog hu ua welded kav.
1. Seamless steel kav yuav muab faib ua kub dov seamless kav, txias-draw kav, precision steel kav, thermal expanded kav, txias spinning kav thiab extruded kav raws li cov txheej txheem ntau lawm.
Seamless steel kav yog ua los ntawm cov pa roj carbon zoo los yog hlau alloy, thiab muab faib ua kub dov thiab txias dov (kos).
2. Welded steel kav tau muab faib ua rau hauv cov kav dej welded, hluav taws xob welded (kuj welded) kav thiab tsis siv neeg arc welded kav vim lawv cov txheej txheem vuam sib txawv. Lawv tau muab faib ua cov kav dej ncaj nraim thiab cov kav dej sib txuas vim lawv cov ntaub ntawv sib txawv. Lawv tau muab faib ua ob hom ntxiv vim lawv cov duab kawg. Rau puag ncig welded kav thiab tshwj xeeb-puab (square, ca, thiab lwm yam) welded kav.
Welded steel kav yog ua los ntawm steel daim hlau dov rau hauv tubular duab thiab welded nrog taub qab seams los yog kauv seams. Nyob rau hauv cov nqe lus ntawm kev tsim, lawv tau muab faib ua welded steel kav rau kev thauj mus los uas tsis tshua muaj siab, muab kauv seam fais welded steel kav, ncaj coil welded steel kav, hluav taws xob welded kav, thiab lwm yam. Seamless steel kav yuav siv tau nyob rau hauv cov kua pneumatic pipelines thiab gas pipelines nyob rau hauv ntau yam lag luam. Cov kav dej welded tuaj yeem siv rau cov kav dej, kav dej, cov kav dej cua sov, cov kav dej hluav taws xob, thiab lwm yam.
Kev faib khoom
Cov kav hlau hlau tuaj yeem muab faib ua cov kav dej carbon, cov kav hlau alloy, cov kav hlau stainless, thiab lwm yam raws li cov khoom siv yeeb nkab (xws li hom hlau).
Cov kav dej muaj peev xwm muab faib ua cov pa roj carbon zoo tib yam cov kav dej thiab cov kav dej zoo carbon zoo.
Cov kav hlau alloy tuaj yeem muab faib ua: cov kav dej tsis tshua muaj hlau, cov kav hlau alloy, cov kav dej siab, thiab cov kav dej muaj zog. Cov kabmob, cov kav dej kub-resistant thiab acid-resistant stainless hlau, precision alloy (xws li Kovar alloy) hlab thiab kub-kub alloy raj, thiab lwm yam.
Kev sib txuas txoj kev faib tawm
Cov kav hlau muaj peev xwm muab faib ua cov kav dej dawb (cov yeeb nkab kawg tsis muaj xov) thiab cov kav dej threaded (cov yeeb nkab xaus nrog cov xov) raws li cov yeeb nkab kawg txuas txoj kev.
Threading tubes tau muab faib ntxiv rau hauv: zoo tib yam threading tubes thiab threading tubes nrog thickened xaus.
Thickened hlau hlab kuj tuaj yeem muab faib ua: sab nraud thickened hlau hlab (nrog rau cov xov sab nraud), cov xov hlau sab hauv (nrog cov xov hauv), thiab sab hauv thiab sab nraud thickened hlau hlab (nrog rau sab hauv thiab sab nraud).
Threaded kav kuj tuaj yeem muab faib ua cov cylindrical lossis conical threaded threaded kav thiab tshwj xeeb threaded threaded kav raws li hom xov.
Tsis tas li ntawd, raws li cov neeg siv xav tau, cov kav hlau xaim feem ntau xa nrog cov yeeb nkab txuas.
Plating yam ntxwv kev faib tawm
Cov kav hlau muaj peev xwm muab faib ua cov kav dej dub (tsis muaj coated) thiab cov kav dej coated raws li cov yam ntxwv ntawm txheej txheej.
Coated kav muaj xws li galvanized kav, aluminium-plated kav, chrome-plated kav, aluminized kav thiab lwm yam alloy-txheej steel kav.
Cov kav dej coated muaj xws li cov kav dej coated sab nrauv, cov kav dej coated sab hauv, thiab cov kav dej sab hauv thiab sab nrauv coated. Cov txheej txheem siv feem ntau suav nrog cov yas, epoxy resin, thee tar epoxy resin thiab ntau yam iav hom los tiv thaiv corrosion txheej.
Galvanized kav tau muab faib ua: KBG kav, JDG kav, threaded kav, thiab lwm yam.
Classification Purpose Classification
