ERW (Electric Resistance Welding) ipayipi lensimbikubhekiselwa kulo njengepayipi le-ERW noma ipayipi elishiselwe i-HF, linezinzuzo eziningi njengokulandelayo:

1) ukusebenza kahle kokukhiqiza okuphezulu, izindleko eziphansi, intengo yayo imayelana ne-UOE seam eqondile engaphansi kwe-arc welded steel, 85%;

I-2) ukunemba okuphezulu kwe-dimensional, ukujikeleza kwayo (i-Roundenss) iphakeme kune-spiral welded pipe, umlingani angasindisa amahora amaningi ensimini;

3) ubuso obushelelezi, ukubukeka okuhle, okulungele ukumbozwa kwangaphakathi nangaphandle.Esikhathini esedlule, ukuthembeka okubi kokushisela amapayipi e-ERW, amapayipi kube nenani elikhulu lezingozi, ngaleyo ndlela kunciphisa ukusetshenziswa kwepayipi le-ERW.Muva nje, i-Zhejiang Jinzhou Group itshale imali eningi, ngemizamo ehlanganyelwe yabacwaningi nomkhiqizi wamapayipi, lesi simo sishintshe kakhulu ikhwalithi ye-ERW yensimbi yokushisela ipayipi ingaqhathaniswa ne-LSAW eqhathanisekayo.

Inqubo yepayipi le-ERW ukuthatha izinyathelo ezilandelayo:

1)lawula okokufaka kokushisa enqubeni, izici eziningi ezithinta okokufaka kokushisa, eyokuqala i-convergence angle (Convergency Angle).Imiphumela yabonisa ukuthi, esimweni sezinye izici ezingaguquki, i-convergence angle inkulu kakhulu ukubanga ukushisela okubandayo, i-convergence angle incane kakhulu izoholela ekushiseni kakhulu.Esinye isici esithinta ipayipi lokufaka elishisayo kwijubane eliya phambili lomugqa wokwakha.Imiphumela ibonisa ukuthi uma kwenzeka kwezinye izici njalo, ijubane lishesha kakhulu lingabangela ukushisela okubandayo, okuhamba kancane, kungaholela kalula ekushiseni.

2)thuthukisa ulayini wefekthri yeshubhu etholakala ngokuzenzakalelayo e-Jinzhou, ukuze kuqinisekiswe ikhwalithi yepayipi le-ERW, ukutholwa kwamaphutha eziteshi eziningi kubuchwepheshe bamapayipi.Umugqa wokukhulula ezinhlangothini zombili zokuhlolwa kwe-ultrasonic, ukuhlolwa kwamanje kwe-eddy ngemva kokuqedwa kokushisela.Ngaphezu kwalokho, inani lokuhlola okubukwayo, kanye nesampula yokuhlolwa kokucaba nokunye ukuhlolwa kwezakhiwo zomshini.
