1. Dab tsi yog qhov kub thiab txias uas koj cov kav dej welded tuaj yeem tiv taus?
Qhov kub thiab txias nyob ntawm cov khoom siv: 1) Carbon steel kav: -20℃txog 350 degree; 2) Stainless hlau kav (304): -196℃rau 870 degree; 3) Alloy steel kav: -40℃txog 550 degree. Peb tuaj yeem pom zoo cov ntaub ntawv tsim nyog raws li koj qhov kev siv kub.
2. Koj puas xa cov kav dej xa mus rau txhua lub tebchaws?
Yog lawm. Peb muaj kev nplua nuj xa tawm thiab tuaj yeem xa mus rau txhua lub teb chaws thiab cheeb tsam hauv ntiaj teb, suav nrog Tebchaws Europe, Amelikas, Southeast Asia, Africa, Middle East, thiab lwm yam. Peb koom tes nrog cov tuam txhab kev lag luam logistics kom muaj kev nyab xeeb thiab xa khoom sai.
3. Koj puas tuaj yeem muab daim ntawv teev nqi rau koj cov kav dej welded?
Yog lawm. Tus nqi ntawm cov kav dej welded nyob ntawm cov khoom siv, specification, kom muaj nuj nqis thiab kev kho deg. Thov hu rau peb nrog koj cov kev cai tshwj xeeb, thiab peb yuav muab cov ncauj lus kom ntxaws thiab sib tw nqi rau koj.
4. Dab tsi yog qhov txawv ntawm kub-dip galvanizing thiab electro-galvanizing rau welded kav?
Kub-dip galvanizing: Cov yeeb nkab yog immersed nyob rau hauv molten zinc, nrog ib tug tuab zinc txheej (80-100μm), muaj zog corrosion kuj, haum rau sab nraum zoov thiab hnyav ib puag ncig. Electro-galvanizing: zinc txheej yog tsim los ntawm electrolysis, nrog ib txheej zinc nyias (10-20μm), du nto, haum rau sab hauv tsev thiab me me corrosion.
5. Yuav ua li cas tswj cov kav dej welded kom ntev lawv lub neej kev pab?
1) Kev tshuaj xyuas tsis tu ncua: Tshawb xyuas qhov chaw rau corrosion, tawg thiab lwm yam tsis xws luag; 2) Ntxuav qhov chaw: Tshem tawm cov av thiab xeb nrog txhuam los yog xab npum; 3) Re-coat: Rau cov xim pleev xim lossis cov kav dej galvanized, rov- txheej txheej thaum lub txheej puas lawm; 4) Tsis txhob sib cuag nrog cov kua qaub thiab alkalis kom tiv thaiv corrosion.
