Kev tsim cov txheej txheem ntawm S235JRH Structure Spiral Submerged Arc Welded Pipe
S235JRH structural kauv submerged arc welded yeeb nkab yog tsim siv kub-rolled steel sawb los ntawm kauv winding thiab submerged arc vuam. Ua ntej, cov hlau sawb txuas ntxiv dov ntawm ib lub kaum sab xis los tsim cov yeeb nkab. Then, full penetration welding is achieved through double-sided submerged arc welding, resulting in a dense metallurgical bond under flux protection. Tom qab tsim, cov txheej txheem xws li sizing thiab straightening, tsis yog - kuaj kev puas tsuaj, thiab kev sim hydrostatic yog ua los xyuas kom meej qhov tseeb qhov tseeb thiab lub zog ntawm cov yeeb nkab, thaum kawg tsim cov kauv welded yeeb nkab haum rau load-cov kabmob lub tsev.
Hais txog peb
GNEE STEEL tau tsim nyob rau xyoo 2008 thiab feem ntau koom nrog kev xa tawm ntawm cov khoom hlau. Peb muab tag nrho - kev pabcuam kev pabcuam, los ntawm kev xaiv lub Hoobkas thiab kev tshuaj xyuas zoo rau kev xa khoom thiab cov ntaub ntawv, ua kom muaj kev cuam tshuam -kev pauv dawb thiab ntawm - lub sijhawm xa khoom. Tsis tas li ntawd, peb muaj kev nkag siab tob txog kev lag luam thoob ntiaj teb kev xav tau thiab cov qauv, ua rau peb muab cov lus qhia xaiv kev tshaj lij thiab cov ntaub ntawv kev lag luam.
