Qhov tseeb ntawm kev pab cuam lub hnab ntawv ntawm lub hnab ntawv submerged-arc welded pipe

Nyob rau hauj lwm no, cov tub lag luam siv rau kev tshuav tuab dej thiab kev ua haujlwm tshuav tuab dej. Cov tub lag luam ua haujlwm tshuav tuab dej siv nyob rau hauj lwm ntau yam tshuav tuab dej yog spiral submerged arc welded steel pipes thiab straight seam double-sided submerged arc welded steel pipes. Vim li cas spiral submerged arc welded pipe yog qhov ua los ntawm kev txhawb nqa thiab nws lub thickness yog qhov xwm, kev pab cuam ntawm qhov chaw ua haujlwm yog qhov ua tiav los ntawm kev kho qhov chaw ua haujlwm. Tom qab ntawv, muaj ob peb qhov tshwj xeeb ntawm spiral submerged arc welded pipe, xws li ntev ntev, kev tsis nyob siab siab thiab kev nyab xeeb ntawm qhov chaw ua haujlwm. Nrog rau kev zoo siab dua rau kev tshuav tuab dej thiab kev ua haujlwm tshuav tuab dej, lawv tsis ua haujlwm nyob rau qhov chaw uas muaj peev xwm thiab qhov chaw uas muaj kev nyab xeeb siab, thiab cov tub lag luam loj dua yog kev ua haujlwm ua ntej los ntawm spiral welded pipes.

Ntawm no, Tshuas teb chaws ua siab rau kev pab cuam huv ntawm kev lag luam hluav taws thiab hluav taws nyob rau lub teb cheeb Hua Dong. Tom qab kev pab cuam huv ntawm kev lag luam hluav taws mus rau qab zog ntawm lub ntug, cov tub lag luam nyob rau hauv ntug tau txiav txim los ntawm kev hloov pauv ntawm nruj, siab thiab kev hloov qhob, thiab qhov teeb meem ntawm kev hloov qhob tseem pom, uas yog qhov chaw ntxoov ntxoo ntawm cov tub lag luam uas muaj kev ua haujlwm. Rau lub hom phiaj ua siab rau kev lag luam thiab kho kom cov tub lag luam hauv ntug mus rau qhov zoo nkag siab, cov tub lag luam hauv ntug tseem siv cov tub lag luam uas muaj kev ua haujlwm. Yog li ntawd, hn compared with spiral welded pipe, straight welded pipe has higher dimensional accuracy and easier repair welding, so from this aspect, straight welded pipe is also the first choice.

Kev lag luam, ua tsev, kev lag luam tshuaj lom neeg thiab lwm yam kev lag luam xav tau cov ntim hlau uas muaj cov hlau hlau. Nyob rau hauj lwm no, lub ntim hauv ntawm qhov chaw ntim tau sau ua ntim tom qab forging nyob rau hauv kev lag luam siv tshuaj, uas yog qhov ua haujlwm ntau, siv sijhawm ntau thiab siv khoom ntau. Yog tias koj siv cov ntim hlau hlau hlau hlau, nws yuav muaj cai rau koj txo ntau ntau. Tom qab ntawd, vim li qhov xav tau ntawm cov kev lag luam zoo li ntawd, cov ntim hlau hlau hlau thiaj li siv rau cov ntim ua tsev; cov ntim hlau hlau hlau kuj tseem cawj ua rau cov ntim tshuaj lom neeg.
