LSAW umbhobho wentsimbingumbhobho wentsimbi ome ngobude.Ngokuqhelekileyo yahlulahlulwe ibe yi-metric welded steel pipe, i-welded thin-walled pipe, i-oyile yokupholisa isiguquli njalo njalo.Umbhobho odityanisiweyo othe ngqo unenkqubo elula yokuvelisa, ukusebenza kakuhle kwemveliso, ixabiso eliphantsi, kunye nophuhliso olukhawulezayo.Umbhobho wentsimbi we-LSAW ngokwenkqubo yemveliso unokwahlulwa ube ngumbhobho wentsimbi womthungo ophezulu-frequency kunye ne-arc entywiliselweyo edityanisiweyo ethe tye ipayipi yentsimbi yomthungo.Imibhobho yentsimbi yomthungo entywilweyo entywiliselweyo yahlulwe yaba yi-UOE, RBE, kunye nemibhobho yentsimbi ye-JCOE ngokweendlela zayo ezahlukeneyo zokubumba.Oku kulandelayo kuchaza owona mbhobho wentsimbi womthungo oqhelekileyo oqhelekileyo ophezulu kunye ne-arc entywiliselweyo edityanisiweyo ethe tye yokwenza umbhobho wentsimbi.

• Ukubetha: Emva kokuba ipleyiti yensimbi esetyenziselwa ukuvelisa i-arc-diameter enkulu edibeneyo i-arc welded straight-joint steel pipe ingena kumgca wokuvelisa, ukuhlolwa kwe-ultrasonic yeplate epheleleyo kuqala kwenziwa;

 

• Umphetho wokugaya: Ngokusebenzisa umatshini wokusila, imiphetho emibini yepleyiti yentsimbi inamacala amabini agayiweyo ukuze afezekise ububanzi bepleyiti efunekayo, iplate edge parallelism kunye nokumila kwegroove;

 

• Ukugoba kwangaphambili: Umatshini wokugoba kwangaphambili wokugoba kwangaphambili ukwenzela ukuba umgca webhodi ube ne-curvature ehambelana neemfuno;

 

• Ukubumba: Okokuqala, isiqingatha sepleyiti yentsimbi egobe ngaphambili sigximfizwa kwaye sigximfizwe kwimilo ethi "J" kumatshini wokwenza i-JCO.Esinye isiqingatha sepleyiti yensimbi siphinde sigobe kwaye sicinezelwe kwimilo "C" ukwenza ukuvula.Ubume "O".

 

• Ukuwelda kwangaphambili: Emva kokusekwa komthungo othe tye odityaniswe nentsimbi yombhobho wentsimbi kunye ne-welding eqhubekayo usebenzisa i-gas shielded welding (MAG);

 

• I-welding yangaphakathi: Sebenzisa i-arc ye-arc ethe nkqo yeentambo ezininzi (ukuya kuthi ga kwiingcingo ezine) ukuweldisela ngaphakathi kumbhobho wentsimbi womthungo othe tye;

 

• Ukuwelda kwangaphandle: Sebenzisa i-arc yokuwelda ethe nkqo yeentambo ezininzi ukuwelda ngaphandle kombhobho wentsimbi we-LSAW;

 

• Ukuhlolwa kwe-Ultrasonic I: Ukuhlolwa kwe-100% ye-welds yangaphakathi nangaphandle ye-longitudinal welded steel pipe kunye nesiseko sesinyithi kumacala omabini e-weld;

 

• Ukuhlolwa kwe-X-reyi I: I-100% yokuhlolwa kwe-X-reyi yoshishino lwe-X-reyi ye-welds yangaphakathi nangaphandle, kusetyenziswa iinkqubo zokucwangcisa imifanekiso ukuqinisekisa uvakalelo lokubona;

 

• Ububanzi obandisiweyo: Ubude obugcweleyo bombhobho wensimbi odibeneyo odibeneyo we-arc we-arc odibeneyo uyandiswa ukuze kuphuculwe ukuchaneka kwe-dimensional yombhobho wensimbi kunye nokuhanjiswa koxinzelelo lwangaphakathi lombhobho wensimbi kuphuculwe;

 

• Uvavanyo loxinzelelo lwe-Hydraulic: Ububanzi beengcambu zombhobho wensimbi owandisiweyo uvavanywa kumatshini wokuvavanya i-hydrostatic ukuqinisekisa ukuba umbhobho wensimbi udibana noxinzelelo olufunekayo lovavanyo.Umatshini unokurekhoda ngokuzenzekelayo kunye nemisebenzi yokugcina;

 

• I-Chamfering: Emva kokudlula ukuhlolwa, umbhobho wensimbi ucutshungulwa ngokuphela kombhobho ukufikelela kumbhobho ofunekayo ubungakanani begroove;

 

• Ukuhlolwa kwe-Ultrasonic II: Ukuhlolwa kwe-Ultrasonic kwenziwa enye enye kwakhona ukujonga iziphene ezinokuthi zenzeke kwimibhobho yentsimbi edibeneyo edibeneyo emva kokwandiswa kobubanzi kunye noxinzelelo lwamanzi.

 

• Uviwo lwe-X-ray II: Ukuhlolwa kwe-X-ray ye-industrial TV kunye nokuhlolwa kwe-tube-end weld seam yeetyhubhu zetsimbi emva kokwandiswa kobubanzi kunye novavanyo loxinzelelo lwe-hydrostatic;

 

• Ukuhlolwa kwe-particle magnetic particle: Olu hlolo lwenziwa ukufumana iziphene zokuphela ityhubhu;

 

• I-Anti-corrosion kunye ne-coating: Umbhobho wensimbi ofanelekileyo uchasene ne-corrosion kunye nokugqoka ngokweemfuno zomsebenzisi.
