Ipayipi elishiselwe ngomthungo oqondile (Ipayipi lensimbi elishiselwe i-ERW eliqondile) kwakhiwa epuleti eligoqiwe elishisayo lomshini wokwenza, umphumela wesikhumba kanye nomphumela oseduze we-high frequency current, ukuncibilika konqenqema lwepayipi lokushisa ukuya ku-extrusion roller pressure welding ukuze kuzuzwe ukukhiqizwa.

Ukusetshenziswa kwendlela ye-high-frequency resistance welding ekukhiqizeni amapayipi ngeminyaka yawo-1950 kuye kwafakazela ukwanda kobuchwepheshe bokukhiqiza obuvuthiwe kanye nokwenza ngcono okuqhubekayo kwekhwalithi yomkhiqizo kule minyaka eyishumi edlule noma ngaphezulu.

Okokuqala, ngekhwalithi yezinto zokusetshenziswa, ukukhiqizwa kwepayipi yensimbi ye-ERW kuye kwathuthukiswa kakhulu, ukwakheka komklamo wensimbi we-carbon low, low P, S, micro-alloying; inqubo yokuncibilikisa ukuncibilikisa, ukucwengisiswa kwe-ladle, ukukhipha i-vacuum degassing, ukusakaza okuqhubekayo nobunye ubuchwepheshe obusha Ngaphezu kwenqubo yokugingqika elawulwa yi-ERW kanye nenqubo ebandayo, ubuchwepheshe buye benza usayizi wokubukeka wemicu yensimbi egoqiwe eshisayo yamashubhu ensimbi amakhulu naphakathi e-ERW ukuze kuthuthukiswe kakhulu izinga lokubukeka, izakhiwo zomzimba kanye nezakhiwo zamakhemikhali. Amapayipi ensimbi akhiqizwe yi-Baoshan Iron and Steel Company, izinga eliphezulu kakhulu lensimbi egoqwayo eshisayo ezweni lami, ahlangabezane nezinga le-American Petroleum Institute API 5L futhi asezingeni eliphezulu lamazwe ngamazwe.

Kulandelwa ububanzi obuphakathi nendawo obukhulu ERW ukubumba Welding kanye nokwelashwa ukushisa inqubo inqubo yokukhiqiza ukuze kuzuzwe ukulawula okuzenzakalelayo computer, imvamisa high kanye nekhompyutha othomathikhi isinxephezelo uhlelo Welding inqubo ukushisa okokufaka amandla kulawulwa ngempumelelo ukuvimbela Welding ukushisa okokufaka Welding kubanda okubangelwa low okokufaka ukushisa kwe-welding kanye nokuvutha okweqile okubangelwa amandla aphezulu. Ukulawulwa kokushisa kokushisa kuvumela inqubo yokwelapha ukushisa ukuze kufinyelele imiphumela engcono kakhulu ngokusho kwezidingo zenqubo, ukuqinisekisa ngokuphumelelayo ikhwalithi ye-welding yepayipi yensimbi kanye nendawo ethintekile ukushisa.

Ngaphezu kwalokho, inqubekelaphambili yobuchwepheshe bokuhlola ipayipi le-ERW tube straight seam welded izuze umonakalo ophelele we-ultrasonic noma ungaxhunyiwe ku-inthanethi we-weld weld engozini, futhi ukuhlolwa kwengcindezi ye-hydraulic kungase kube ngaphansi kokuqondisa kwekhompyutha, ukuhlolwa kokucindezeleka kanye nezidingo zokulawula. Ukukhuthazwa kanye nokuqaliswa kochungechunge olujwayelekile kanye nokucaciswa kwe-APIQ1 ISO9000 kuqinisekisa ukuqinisekiswa kwekhwalithi kuyo yonke inqubo yokukhiqiza, ukuhlola, ukuthengisa kanye nenkonzo yamapayipi ensimbi othungelwano oluqondile lwe-ERW aphakathi nendawo namakhulu.

Eminyakeni yamuva nje, amazwe ahlukahlukene aye amukela ngenkuthalo ipayipi le-ERW eliqondile lomthungo elishiselwe kanye nepayipi elivunguzayo elishiselwe ipayipi elingenamthungo endaweni, emazweni athuthukile, i-ERW eqondile yomphetho wepayipi ububanzi Ф610mm ngaphansi, ipayipi lensimbi le-ERW selifinyelele cishe ku-70% wengxenye. Umthamo wethu wokukhiqiza we-ERW Longitudinal nawo uthuthukile.
