Ipayipi yensimbi ye-LSAWiyipayipi lensimbi elihambisana nobude. Imvamisa ihlukaniswe ngepayipi lensimbi elishiselwe i-metric, ipayipi elinezindonga ezincane elishiselwe, ipayipi likawoyela elipholisa i-transformer njalonjalo. Ipayipi elihlanganisiwe le-seam eliqondile linenqubo yokukhiqiza elula, ukusebenza kahle kokukhiqiza okuphezulu, izindleko eziphansi, kanye nentuthuko esheshayo. Ipayipi lensimbi le-LSAW ngokwenqubo yokukhiqiza lingahlukaniswa libe ipayipi lensimbi le-frequency eliphezulu eliqondile kanye ne-arc engaphansi eshiselwe ipayipi lensimbi lomthungo. Amapayipi ensimbi afakwe ngaphansi kwamanzi ashiselwe ngomthungo oqondile ahlukaniswe abe amapayipi ensimbi i-UOE, RBE, kanye ne-JCOE ngokwezindlela zawo ezihlukene zokwakha. Okulandelayo kuchaza ipayipi lensimbi lomthungo elivama kakhulu elinemvamisa ephezulu kanye nenqubo yokwakhiwa kwepayipi lensimbi elicijile le-arc elishiselwe oqondile.

• Ukushaya: Ngemva kokuba ipuleti lensimbi elisetshenziselwa ukukhiqiza amapayipi ensimbi anobubanzi obuyi-arc-arc ashiselwe aqondile ahlangene angena emgqeni wokukhiqiza, ukuhlolwa kwe-ultrasonic kwepuleti eligcwele kwenziwa kuqala;

 

• Unqenqema lokugaya: Ngomshini wokugaya onqenqemeni, imiphetho emibili yepuleti lensimbi igaywe kabili ukuze kuzuzwe ububanzi bepuleti elidingekayo, ukuhambisana konqenqema lwepuleti kanye nokuma kwe-groove;

 

• Ukugoba kwangaphambili: Umshini wokugoba ngaphambili wokugoba ngaphambili ukuze umkhawulo webhodi ube ne-curvature ehlangabezana nezidingo;

 

• Ukubumba: Okokuqala, ingxenye yensimbi egobe kuqala iyagxivizwa futhi ingxivizwe kusimo esithi "J" emshinini wokwenza i-JCO. Enye ingxenye ye-steel plate nayo igotshiwe futhi icindezelwe kumumo othi "C" ukuze kwakheke ukuvuleka. Umumo othi "O".

 

• Pre-welding: Ngemva ukwakheka iqonde umthungo ashiselwe steel ipayipi amalunga kanye Welding okuqhubekayo usebenzisa igesi ivikelwe Welding (MAG);

 

• Ukushisela kwangaphakathi: Sebenzisa i-arc welding enezintambo eziningi ezimile ezimile (kufika ezintanjeni ezine) ukushisela ngaphakathi kwepayipi lensimbi lomthungo oqondile;

 

• Ukushisela ngaphandle: Sebenzisa i-arc welding enezintambo eziningi ezimile mpo ukuze ushisele ngaphandle kwepayipi lensimbi le-LSAW;

 

• Ukuhlolwa kwe-Ultrasonic I: Ukuhlolwa okungu-100% kokushisela kwangaphakathi nangaphandle kwepayipi lensimbi elishiselwe longitudinal kanye nesisekelo sensimbi ezinhlangothini zombili ze-weld;

 

• Ukuhlolwa kwe-X-ray I: 100% Ukuhlolwa kwe-X-ray yezimboni ze-X-ray kwamashisela angaphakathi nangaphandle, kusetshenziswa amasistimu okucubungula izithombe ukuze kuqinisekiswe ukuzwela kokutholwa;

 

• Ububanzi obunwetshiwe: Ubude obugcwele bepayipi yensimbi yomthungo eqondile engaphansi kwamanzi e-arc bunwetshwa ukuze kuthuthukiswe ukunemba kobukhulu bepayipi lensimbi kanye nokusatshalaliswa kokucindezeleka kwangaphakathi kwepayipi lensimbi kuyathuthukiswa;

 

• Ukuhlolwa kwengcindezi ye-Hydraulic: Ububanzi bempande yepayipi lensimbi elinwetshiwe lihlolwa emshinini wokuhlola we-hydrostatic ukuze kuqinisekiswe ukuthi ipayipi lensimbi lihlangabezana nengcindezi yokuhlola edingekayo. Umshini unemisebenzi yokuqopha neyokugcina ngokuzenzakalelayo;

 

• I-Chamfering: Ngemva kokudlulisa ukuhlolwa, ipayipi lensimbi licutshungulwa ekupheleni kwepayipi ukuze lifinyelele usayizi odingekayo wokuphela kwepayipi;

 

• Ukuhlolwa kwe-Ultrasonic II: Ukuhlolwa kwe-Ultrasonic kwenziwa ngamunye ngamunye futhi ukuze kuhlolwe ukukhubazeka okungenzeka ku-straight seam welded steel pipes ngemva kokunwetshwa kobubanzi nokucindezela kwamanzi.

 

• Ukuhlolwa kwe-X-ray II: Ukuhlolwa kwethelevishini yezimboni ze-X-ray kanye nokuhlolwa kwe-tube-end weld seam yamashubhu ensimbi ngemva kokunwetshwa kobubanzi nokuhlolwa kwengcindezi ye-hydrostatic;

 

• Ukuhlolwa kwezinhlayiyana ze-tube ekupheleni: Lokhu kuhlolwa kwenziwa ukuze kutholwe amaphutha okuphela kwe-tube;

 

• I-Anti-corrosion kanye ne-coating: Ipayipi lensimbi elifanelekayo liyi-anti-corrosion kanye ne-coating ngokuvumelana nezidingo zomsebenzisi.
