Raws li kev siv vuam, cov kav hlau welded tuaj yeem muab faib ua cov kav dej arc-welded, high-frequency los yog tsawg-frequency resistance-welded kav, gas-welded kav, rauv-welded kav, Bundy tubes, thiab lwm yam.
Electric Welded Steel Pipes: Siv rau hauv cov roj drilling, machinery manufacturing, thiab lwm yam lag luam.
Furnace-Welded Pipes: Yuav siv tau raws li cov kav dej thiab cov pa roj, nrog cov kab loj-ntev ncaj-seam welded kav haum rau cov roj thiab roj tsheb thauj mus los, thiab cov kav hlau txuas txuas tau siv rau hauv cov roj thiab roj, cov kav dej, cov kav dej. , lwm.
Raws li cov duab ntawm lub vuam seam, welded steel kav yuav muab faib ua ncaj-seam welded kav thiab kauv-welded kav.
Ncaj-Seam Welded Pipes: Featuring yooj yim cov txheej txheem ntau lawm, siab ntau lawm efficiency, thiab cov nqi qis, lawv tau tsim sai heev.
Kauv-Welded Pipes: Feem ntau muaj zog dua cov kav dej ncaj nraim, lawv tuaj yeem tsim cov kav dej loj dua los ntawm cov kab nqaim thiab cov kav dej sib txawv ntawm qhov sib txawv ntawm qhov dav dav. Txawm li cas los xij, piv rau cov kav dej ncaj nraim ntawm tib qhov ntev, qhov vuam seam ntev nce los ntawm 30-100%, thiab qhov ceev ntau lawm yog qis dua. Yog li ntawd, cov kav dej me me feem ntau txais kev sib txuas ncaj nraim, thaum cov kav dej loj dua feem ntau siv kauv vuam.
Kauv-seam welded steel kav txuas ntxiv mus rau hauv tsis siv neeg submerged arc welded steel kav thiab high-frequency welded steel kav.
a. Tsis Siv Neeg Submerged Arc Welded Steel Pipes nrog Kauv Seams tau muab faib ua Class A thiab Class B kav raws li qhov siab ntawm qhov nruab nrab conveyed. Class A kav feem ntau welded nrog zoo tib yam carbon steel Q235, Q235F, thiab zoo tib yam low-alloy structural steel 16Mn, thaum Class B kav yog welded nrog Q235, Q235F, Q195, thiab lwm yam steels, siv rau cov dej tsis tshua muaj siab.
b. High-Frequency Welded Steel Pipes nrog Kauv Seams tseem tsis tau tsim ib qho khoom sib koom ua ke thiab feem ntau yog tsim los ntawm cov pa roj carbon zoo tib yam Q235, Q235F, thiab lwm yam.
Raws li lawv daim ntawv thov, welded steel kav yuav muab faib mus rau hauv dav welded kav, galvanized welded kav, oxygen-blowing welded kav, hluav taws xob xaim conduit kav, metric welded kav, idler kav, tob-zoo twj tso kua mis, automotive kav, transformer kav. , hluav taws xob welded nyias-phab ntsa kav, hluav taws xob welded tshwj xeeb-zoo li tus kav, thiab kauv-welded kav.
General Welded Pipes: Siv rau kev thauj cov kua dej uas tsis tshua muaj siab, ua los ntawm Q195A, Q215A, Q235A steel, lossis lwm yam yooj yim weldable me me steel. Raws li kev ntsuam xyuas hydraulic, dabtsi yog khoov, thiab flattening, lawv muaj cov kev xav tau tshwj xeeb ntawm qhov zoo. Feem ntau xa mus rau qhov ntev ntawm 4-10m, feem ntau mus rau kev teev lossis ntau qhov ntev. Lawv cov kev qhia tshwj xeeb yog qhia los ntawm nominal diameters (hauv millimeters lossis nti), uas yuav txawv ntawm qhov tseeb diameters. Raws li phab ntsa thickness, lawv raug cais raws li cov kav dej tsis tu ncua thiab thickened, thiab los ntawm cov ntaub ntawv kawg, raws li threaded los yog unthreaded.
Galvanized Steel Pipes: Txhawm rau txhim kho corrosion, cov kav hlau tsis tu ncua (cov kav dej dub) yog galvanized, los ntawm kub-dip galvanizing (thicker txheej) lossis electro-galvanizing (qis nqi).
Oxygen-Blowing Welded Pipes: Cov kav dej me me uas siv rau hauv steelmaking oxygen tshuab, xws li 3/8 "mus rau 2" inch, ua los ntawm 08, 10, 15, 20, lossis Q195-Q235 steel strips. Qee qhov ua rau aluminizing tiv thaiv corrosion.
Cov Hluav Taws Xob Cov Hluav Taws Xob Cov Hluav Taws Xob: Cov pa roj carbon steel hluav taws xob welded kav siv rau hauv cov pob zeb thiab ntau yam kev faib hluav taws xob, nrog rau cov kab nominal xws li ntawm 13-76 hli. Featuring nyias phab ntsa, lawv feem ntau coated los yog galvanized ua ntej siv thiab yuav tsum tau txias dabtsi yog khoov kuaj.
Metric Welded Pipes: Qhia nyob rau hauv seamless yeeb nkab hom, qhia los ntawm sab kab * phab ntsa thickness (nyob rau hauv millimeters), welded los ntawm kub dov los yog txias-dov strips ntawm zoo tib yam carbon steel, high-zoo carbon steel, los yog tsawg-alloy steel, los yog txias-draw tom qab vuam. Metric welded kav yog cais raws li niaj zaus thiab nyias-walled, nrog rau yav tas los siv rau cov yam ntxwv yam xws li kis tau tus mob shafts los yog cov dej thauj mus los, thiab tom kawg rau rooj tog, teeb pom kev zoo fixtures, thiab lwm yam. Lawv yuav tsum tau raws li lub zog thiab dabtsi yog khoov xeem.
