Kauv steel kav yog tsim los ntawm coiled strip steel, tsim los ntawm txias extrusion thiab welded siv submerged arc vuam txheej txheem. Lub sawb hlau yog pub rau hauv lub vuam tsev, dov los ntawm ntau lub chais, thiab maj mam coiled mus rau hauv ib lub voj voog cov yeeb nkab dawb nrog qhib seam. Qhov sib txawv ntawm cov weld seams yog tswj ntawm 1-3 mm los ntawm kev kho lub siab ntawm cov nyem chais, kom ntseeg tau tias flush alignment ntawm ob qhov kawg ntawm lub weld.
Kauv steel kav tuaj yeem tsim nrogib leeg -sab vuamlos yogob -sab vuam. Cov kav dej welded yuav tsum ua raws li cov qauv hauv qab no:
Hydrostatic Pressure Test- Ua kom cov pa tawm - pov thawj kev ua tau zoo raws li qhov ntsuas siab.
Weld Tensile zog- Kev sib koom ua ke yuav tsum ua tiav qhov xav tau kev siv tshuab.
Txias Khoov Performance- Lub weld cheeb tsam yuav tsum tuaj yeem khoov yam tsis muaj kev tawg.
Kev faib tawm:
Los ntawm Khoom:Stainless hlau, carbon hlau, qis- alloy steel, alloy steel, thiab lwm yam.
Los ntawm Txheej Txheem:Ob -sab submerged arc vuam, ib zaug -sab submerged arc vuam.
Los ntawm Daim Ntawv Thov:
Kev thauj cov kua dej (xws li dej, roj, roj).
Piping kav (piv txwv li, kev tsim kho hauv paus).
Los ntawm Kev Kub Siab Resistance:
Tsawg- cov kav dej siab.
Standard siab-cov kav dej tiv taus.
Los ntawm Manufacturing Standards:
National (GB), Asmeskas (API / ANSI), Japanese (JIS), Lavxias (GOST), thiab lwm yam.
Yam ntxwv:
Siab corrosion kuj thiab plasticity.
Lub zog siab dua piv rau ncaj- seam welded kav.
Tso cai tsim cov kav loj - txoj kab uas hla los ntawm nqaim sawb hlau.
Flexible yeeb nkab txoj kab uas hla tso zis siv tib yam raw khoom dav.
Daim ntawv thov:
Hauv tsev:Kev siv dej, kev tso dej, kev tsim kho hauv nroog.
Industrial:Petroleum, tshuaj, hluav taws xob, kev ua liaj ua teb irrigation.
Gas Thauj:Natural gas, chav, LPG.
Kev siv tus qauv:Piling, txuas hniav, docks, txoj kev, thiab architectural moj khaum.
