Qhov sib txawv ntawm kub ncabtxo cov yeeb nkaband LSAW steel pipe yog qhov pib muaj ob lub ntsiab lus hauv qab no:

1, Ua rau muaj qhov sib txawv ntawm cov khoom lag luam zoo vim muaj cov txheej txheem sib txawv, kub ncab txo kuj ua tiav cov txheej txheem tom qab cov txheej txheem vuam ntau zaus uas lsaw steel yeeb nkab tsis tuaj yeem pom —— Longitudinal tsis muaj kab ntshiab sab hauv thiab sab nraud burrs.Lub xub ntiag ntawm Burr yuav cuam tshuam rau lub raj dej - ntws, burr thaiv cov dej ntws ib txwm muaj, ua rau muaj cua daj cua dub.Raws li cov hauv paus ntsiab lus ntawm cov tshuab ua kua, vuam yuav tsum ua kom cov compression hauv zos, kev tsis sib xws ua rau cov yeeb nkab kev nyab xeeb kuj tseem txo qis, kub ncab txo cov txheej txheem steel ntau lawm - tag nrho coj mus rau hauv tus account qhov muaj feem ntawm burrs, txwv tsis pub burr tshem tawm, ua rau nws zoo ib yam. thickness, tsis muaj qhov sib txawv ntawm qhov tsos thiab seamless.Yog li los ntawm qhov kev pom no, kub ncab txo cov yeeb nkab txuas kuj ua tiav qhov kev hloov pauv seamless.

2, Weld zoo ncaj qha txiav txim siab qhov zoo ntawm cov yeeb nkab welded, seamless yeeb nkab yog welded nrog qhov sib txawv loj tshaj.Longitudinal tom qab lub high-frequency welding, ncaj seam teem carbon tsis tuaj yeem raug tshem tawm, weld thiab cov niam txiv tsuas yog koom ua ke thiab tsis tag fused rau hauv ib qho - tsis tuaj yeem sawv qhov kev sim ntawm lub sijhawm thiab lub siab.Kub stretches txo cov high-frequency welding steel yeeb nkab tom qab cua sov mus rau tag nrho cov, tag nrho cov annealing kub ntawm 800 degrees, thiab ces qhib qhov kev hloov, tom qab uas ib tug series ntawm cov txheej txheem, lub weld thiab cov niam txiv lub koom haum kev ua tau zoo - tau ua. tib yam rau qhov ua tiav melting ib qho, ua tau zoo los ntawm seam mus rau seamless hloov.
