Lub siab zaus kuj welded steel hlab muaj cov txheej txheem vuam sib txawv dua li ob hom welded raj. Lub vuam yog tsim los ntawm fusing lub hauv paus khoom ntawm lub cev ntawm cov hlau sawb, thiab nws cov neeg kho tshuab tsis kam yog zoo dua li ntawm ob hom welded raj. Smooth tsos, siab precision, tsis tshua muaj nqi thiab me ntsis weld reinforcement, uas yog zoo rau cov txheej ntawm 3PE anticorrosive txheej. Cov txheej txheem vuam ntawm high zaus welded steel yeeb nkab thiab submerged arc welded yeeb nkab yog qhov sib txawv. Muab hais tias welding tiav tam sim ntawd ntawm kev kub ceev, nws yog qhov nyuaj dua los lav qhov zoo ntawm vuam tshaj submerged arc vuam.

4. Koj qhov kev txiav txim yam tsawg kawg yog dab tsi?
Rau cov khoom hauv Tshuag, peb muab lawv los ntawm ib thooj. Yog tias nws yog qhov kev txiav txim ntau lawm, qhov tsawg kawg nkaus txiav txim ntim yog 3 tons. Thov nco ntsoov tias vim tus nqi siab, tus nqi raws li moq yuav siab dua me ntsis ntawm cov nqe lus fcl.
5. Ua ntej peb koom tes, peb xav tau ib qho qauv los kuaj xyuas qhov zoo, puas yog?
Peb tuaj yeem muab cov qauv dawb rau koj. Yog tias tus nqi piv txwv tsis ntau tshaj 30 las, koj tsuas yog yuav tsum tau them tus nqi xa khoom. Rau cov qauv muaj nuj nqis ntau dua $ 30, ib nrab ntawm tus nqi xa khoom thiab tus nqi coj mus kuaj yuav raug them los ntawm koj thiab ib nrab los ntawm peb.
6. hom kev thauj mus los yog dab tsi?
Hiav txwv freight yog hom tseem ceeb tshaj plaws ntawm kev thauj mus los, peb xaiv txoj kev raws li lub sij hawm thauj mus los sai tshaj plaws thiab pheej yig tshaj; Los yog, yog tias muaj cov lus qhia los ntawm cov neeg siv khoom, peb yuav ua raws li cov lus qhia ntawm tus neeg siv khoom. Thaum nws yooj yim dua, peb kuj xaiv txoj kev tsheb ciav hlau. Rau cov qauv thiab ntawv, lawv yuav raug thauj los ntawm huab cua.
Cim npe nrov: ssaw yeeb nkab, tus neeg muag khoom, kev cai, lag luam wholesale, pheej yig, luv nqi, daim ntawv teev npe, tus nqi qis, hauv Tshuag, dawb qauv
