Ob peb xyoos dhau los, peb lub lag luam tau nqus thiab zom cov thev naus laus zis siab heev ob qho tib si hauv tsev thiab txawv teb chaws.Nyob rau hauv lub sijhawm no, peb lub tuam txhab ua haujlwm ib pab pawg kws tshaj lij tau mob siab rau koj txoj kev nce qib ntawm Kev Tshawb Fawb Hoobkas rau Tuam Tshoj SSAW API 5L Psl2 X52 10 "X Sch80, Peb yeej tsis tso tseg kev txhim kho peb cov txheej txheem thiab kev ua haujlwm zoo los pab kom siv cov kev txhim kho ntawm kev lag luam no. thiab ua tau raws li koj qhov kev txaus siab zoo.Yog tias koj txaus siab rau peb cov khoom, thov hu rau peb dawb.
Ob peb xyoos dhau los, peb lub lag luam tau nqus thiab zom cov thev naus laus zis siab heev ob qho tib si hauv tsev thiab txawv teb chaws.Nyob rau hauv lub meantime, peb lub tuam txhab cov neeg ua hauj lwm ib pab pawg neeg ntawm cov kws txawj mob siab rau koj kev nce qib ntawmTuam Tshoj Weld Pipe, Cov yeeb nkab steel, peb cia siab tias yuav tsim kom muaj kev sib raug zoo ntawm kev lag luam mus sij hawm ntev nrog koj lub tuam txhab muaj txiaj ntsig los ntawm lub sijhawm no, raws li kev sib luag, kev sib raug zoo thiab kev lag luam yeej-yeej los ntawm tam sim no mus rau yav tom ntej."Koj qhov kev txaus siab yog peb txoj kev zoo siab".
Kauv welded yeeb nkab yog tsim los ntawm steel kauj.Lub coil yog unwound thiab ces welded thaum nws tab tom tig mus rau hauv cov duab ntawm cov yeeb nkab.Hloov lub kaum sab xis ntawm cov kauv thiab lub thickness ntawm lub kauj yog txhua yam uas yuav tsum tau hloov ntawm ib lub yeeb nkab loj mus rau lwm qhov.Ob sab ntawm ob chav submerged arc weld nkag mus rau tag nrho cov tuab ntawm cov hlau los xyuas kom meej lub zog ntawm cov yeeb nkab tiav.Tag nrho cov kev ntsuas ntsuas tau pom tias qhov zoo tshaj plaws kauv welded yeeb nkab muaj zog npaum li API yeeb nkab.Lub zog thiab saj zawg zog tsim ntawm kauv welded yeeb nkab ua rau nws cov khoom ntawm kev xaiv rau ntau yam kev siv.

SSAW Pipe (Spiral Submerged Arc-Welding Pipe), kuj hu ua HSAW yeeb nkab (Helical SAW), vuam kab zoo li lub helix.Nws yog siv tib lub vuam thev naus laus zis ntawm Submerged Arc-Vuam nrog LSAW yeeb nkab. nyob rau hauv ib tug kauv kab.
