1. Dab tsi yog cov kev faib tawm los ntawm txoj kev ntau lawm?
Cov kav hlau hlau tuaj yeem faib ua ob pawg raws li cov qauv tsim khoom: Seamless steel kav thiab welded steel kav hlau.
Seamless steel kav tuaj yeem muab faib ua cov kav dej kub, cov kav dej txias, cov kav dej txias, cov kav dej txias ua haujlwm raws li cov qauv siv khoom lag luam.
Seamless steel kav yog tsim los ntawm cov roj carbon ua zoo los yog alloy steel, thiab tau muab faib ua kub-dov thiab txias-dov (txav khaub ncaws txias (kos).
Welded Steel kav yog muab faib ua hluav taws xob welded (kev tawm tsam welded) kav dej thiab tsis siv neeg arc welded kav dej vim tias sib txawv vuam cov txheej txheem. Lawv muab faib ua txoj hlua khi ncaj welded thiab muab kauv welded kav vim muaj ntau hom vuam vuam. Lawv muab faib ua ke welded kav relded thiab cov qauv tshwj xeeb (square, tiaj, thiab lwm yam) welded kav vim lawv cov duab kawg.
Welded steel kav yog ua los ntawm cov phaj hlau dov rau hauv lub raj ntawm lub raj los ntawm cov nqaws tawm los yog muab kauv seams. Hais txog cov kev tsim khoom, lawv tau muab faib ua welded steel kav hlau vuas, etc. Seamless Steel kav yuav siv tau rau ntau yam kua thiab roj pipelines. Welded kav yuav siv tau rau cov kav dej dej, cov kav dej roj, kav kub, thiab lwm yam.
2. Dab tsi yuav tau cais los ntawm cov khoom?
Raws li cov ntaub ntawv (piv txwv li cov khoom hlau), cov kav hlau tuaj yeem faib ua: cov pa roj carbon pipes, cov kav dej alloy, thiab lwm yam.
Cov PCBes carbon tau tuaj yeem faib ua cov roj carbon steel hlau thiab cov roj ua haujlwm zoo rau cov kav dej.
Alloy kav tuaj yeem faib ua: Cov kav dej qis, alloy txheej txheem kav dej, cov kav dej siab, siab zog kav, lub zog siab lub zog, lub zog siab siab, lub zog siab lub zog. Kev coj kabmob kav, kub-resistant thiab acid-resistan deferant stainless kav, precision alloy (xws li Kovar Alloy) kav, thiab cov kav dej kub alloce.
3. Dab tsi yuav tau cais los ntawm txoj kev sib txuas?
Raws li txoj kev sib txuas ntawm cov yeeb nkab kawg, cov kav dej hlau tuaj yeem faib ua cov kav dej kom sib raug zoo) thiab cov xov txuas ntawm cov yeeb nkab kawg).
Cov kav dej ntim tau tuaj yeem faib ua cov kav dej: cov kav dej khov kho thiab cov kav dej threated ntawm cov yeeb nkab kawg.
Thickening xov kav tseem tuaj yeem muab faib ua: cov xov thickening sab nraud (nrog cov xov sab nraud) thiab sab hauv thickening (nrog cov xov sab nraud (nrog xov sab nraud thiab sab hauv thiab sab nraud thiab sab nraud).
Cov kav dej tseem tuaj yeem muab faib ua cov kav dej threaded nrog cov ntawv cylindrical lossis conical xov thiab xov tshwj xeeb raws li xov hom.
Tsis tas li ntawd, raws li cov neeg siv xav tau, cov kav dej feem ntau xa nrog cov yeeb nkab sib koom.
4. Dab tsi yuav tau cais los ntawm kev siv?
Kav rau raj xa khoom. Xws li: cov kav dej seamless rau dej, roj kav, cov kav dej roj, roj pipes, thiab roj thiab roj pob tw ntoo. Kev ua liaj ua teb irrigation dej kais dej Taps nrog cov kav dej thiab cov sprinkler kav dej, thiab lwm yam.
Cov khoom siv thermal bermes. Xws li cov kav dej npau npau npau thiab cov kav dej khov kho, cov pa luam yeeb loj, thiab cov pa luam yeeb loj thiab kub roj boiles boilers.
Kav rau kev lag luam tshuab. Xws li aviation cov kav dej (cov kav dej puag ncig, lub tsheb laij teb oval, cov kav dej ib nrab ntawm cov kav dej khov kho roj
Roj av geological drilling kav dej. Xws li: roj tho kav, cov roj tho kav dej (tho kev lag luam, tho kev siv cov roj ntsha
Kev Siv Kev Lag Luam Kav Dej. Xws li: roj tawg kav dej, cov cuab yeej siv hluav taws xob cua sov thiab cov kav dej storm-resist hlau rau chiv, thiab lwm yam.
Kav rau lwm cov tuam tsev. Xws li: thawv kav dej (high-siab roj kheej raj roj pipes thiab cov khoom lag luam dav hlau, tshuaj ntsuam cov kav dej, cov kav dej txhaj tshuaj, thiab lwm yam.
5. Dab tsi yog cov kev faib tawm raws li cov qauv sib txawv?
Muaj ntau hom thiab cov specifications ntawm cov yeeb nkab steel hlau, thiab lawv cov kev ua tau zoo kuj yog ntau yam. Tag nrho cov no yuav tsum tau txawv raws li cov neeg siv yuav tsum tau ua haujlwm hloov pauv. Feem ntau, cov yeeb nkab cov yeeb nkab tau faib ua cov qauv sib txawv, cov khoom siv cov yeeb nkab, cov yam ntxwv sib txuas, cov yam ntxwv sib txuas, siv.
Cov kav hlau hlau tuaj yeem faib ua ke rau hauv cov kav hlau sib xyaw thiab cov hlau tshwj xeeb zoo li cov duab hlau txuas ntxiv raws li lawv cov duab sib tw.
Tshwj xeeb zoo li tus hlau kav hlau txuas xa mus rau cov kav dej hlau nrog ntau yam uas tsis sib nrug sib nrug. Ntawm lawv, muaj feem ntau: cov kav dej phum, pentagonal pipes, hexagonal hexagonal kav dej, thiab ob chav conveesal, thiab ob chav kav dej. Ob lub txiv ntseej cov kav dej, cov kav dej khov, cov kav dej khov, cov kav dej khov, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej B-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-pipes, cov kav dej b-hom
Cov kav hlau steel tau muab faib ua cov khoom sib luag ntawm cov kav hlau sib luag thiab cov khoom siv hlau hlau Kuj tsis paub meej-ntu (lossis hloov npe-ntu) cov kav hlau sib txawv xa mus rau cov kav hlau steel Lawv feem ntau yog suav nrog cov kav dej sab nraud, cov kav dej sab hauv, cov kav dej sab nraud, cov kav dej sib txuas nrog cov kav dej sib tw, cov kauj vab sib txawv nrog cov kab cua sov nrog ob kab.
