Kauv steel kav yog siv nyob rau hauv cov dej num, kev lag luam petrochemical, tshuaj lom neeg kev lag luam, hluav taws xob fais fab kev lag luam, kev ua liaj ua teb irrigation, thiab kev tsim kho hauv nroog. Kauv steel kav yog ntawm 20 cov khoom tseem ceeb tsim nyob rau hauv kuv lub teb chaws. Rau kev thauj mus los ua kua: siv dej thiab tso dej. Rau kev thauj mus los roj: thee roj, nkev, roj av liquefied. Rau lub hom phiaj: piling kav, txuas hniav; Cov kav dej rau cov docks, txoj kev, cov qauv hauv tsev, thiab lwm yam. Kauv steel yeeb nkab yog ib qho kauv seam steel yeeb nkab welded los ntawm tsis siv neeg ob-xaim ob-sided submerged arc vuam txheej txheem siv sawb steel coil phaj ua raw khoom, qhov kub thiab txias extrusion molding. Lub kauv steel yeeb nkab pub lub sawb mus rau hauv cov yeeb nkab welded. Tom qab tau dov los ntawm ntau lub chais, lub sawb yog maj mam dov los ua ib lub voj voos kheej kheej nrog qhov qhib qhov sib txawv. Kho qhov txo tus nqi ntawm cov menyuam extrusion los tswj qhov sib txawv ntawm qhov sib txawv ntawm 1-3mm, thiab ua rau ob qho tib si kawg ntawm cov vuam sib txuas.

Qhov txawv ntawm kauv steel yeeb nkab thiab precision steel yeeb nkab
Kauv steel kav tuaj yeem muab faib ua ob pawg raws li kev tsim khoom: kauv thiab seamed. Seamed steel kav yog hu ua ncaj seam steel kav. Kauv steel kav yuav muab faib ua kub dov seamless kav, txias-draw kav, precision steel kav, thermally nthuav kav, txias-spinning kav, thiab extruded kav raws li txoj kev ntau lawm. Kauv steel kav yog ua los ntawm cov pa roj carbon zoo los yog hlau alloy thiab tuaj yeem muab faib ua kub dov thiab txias dov (kos). Lub ntsiab feature ntawm kauv steel yeeb nkab yog tias nws tsis muaj vuam seams thiab tuaj yeem tiv taus siab dua.

Cov khoom tuaj yeem ntxhib heev li cam khwb cia lossis txias kos qhov chaw. Welded steel kav tau muab faib ua rau cov kav dej kub, cov kav hluav taws xob welded (kuj welded) kav, thiab cov kav dej tsis siv neeg arc welded vim lawv cov txheej txheem vuam sib txawv. Vim lawv txoj kev vuam sib txawv, lawv tau muab faib ua cov kav dej ncaj nraim welded thiab kauv welded kav. Lawv kuj tau muab faib ua cov kav welded puag ncig vim lawv qhov kawg duab thiab zoo li cov 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 cov txheej txheem, 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. Kauv steel kav yuav siv tau nyob rau hauv cov kua pneumatic pipelines thiab gas pipelines nyob rau hauv ntau yam lag luam. Vuam siv tau rau cov kav dej, kav dej, kav dej, cua sov, kav dej, thiab lwm yam.

Precision steel kav yog cov khoom uas tau tshwm sim nyob rau hauv xyoo tas los no. Lawv feem ntau muaj nruj tolerances thiab roughness nyob rau hauv lub puab thiab sab phab ntsa qhov ntev. Precision steel yeeb nkab yog cov khoom siv high-precision steel yeeb nkab uas tau ua tiav los ntawm kev kos duab txias lossis kub dov. Vim tias tsis muaj oxide txheej ntawm cov phab ntsa sab hauv thiab sab nrauv ntawm cov kav hlau zoo, tsis muaj qhov xau nyob rau hauv siab, siab precision, siab ci, tsis deformation nyob rau hauv txias dabtsi yog khoov, tsis muaj kab nrib pleb thiab flattening, thiab lwm yam., nws yog tsuas yog siv rau tsim cov khoom nrog pneumatic lossis hydraulic Cheebtsam, xws li lub tog raj kheej lossis Roj lub tog raj kheej.
