ERWiri high-frequency resistance welding straight seam welded pombi;LSAWiri pasi pemvura arc welding yakatwasuka musono welded pombi;Ose ari maviri ndeemusono seam welded pombi, asi maitiro ekugadzira akasiyana.Saka haugone kutaura chimwe chazvo pachinzvimbo cheiyo yakatwasuka musono welded pombi.Zvimwe zvakajairika simbi pombi ndizvo SSAW- spiral welded pipe.Yakakwira frequency yakatwasuka seam (ERW) zvinoenderana neiyo welding process yakakamurwa kuita akasiyana induction welding uye kuramba welding mafomu maviri, zvichibva pane inopisa yakatenderedzwa yakafara vhoriyamu seyakagadzirwa zvinhu, kuburikidza nekuenderera mberi kwekugadzira, kukotama, welding, kupisa kupisa, saizi, kutwasanudza, kucheka nzira.Kuenzaniswa neSSAW, kurongeka kwepamusoro, yunifomu yemadziro ukobvu, kunaka kwepamusoro pemhando, kudzvanywa kwepamusoro ndiko kwakanakira.Asi chakashata ndechekuti chigadzirwa chidiki dhayamita yakaonda madziro pombi, weld nyore chizvarwa chinopikisa, isina kukwana fusion, mugero ngura kuremara.Inoshandiswa zvakanyanya senge gasi reguta, crude oil transportation.

Izvo zvinhu zveLSAW simbi pombi imwe gobvu simbi ndiro, iyo simbi muforoma kana kuumba muchina wepakati-voltage (vhoriyamu), uchishandisa kaviri-mativi akanyura arc welding Yayo yakapedzwa chigadzirwa yakatarwa mhando yakafara, kuoma kweiyo weld, plasticity, Kufanana kwakanaka uye kusimba, nehupamhi hwepombi dhayamita, kukora kwemadziro, kupikisa kwakasimba kune yakanyanya kudzvanywa, yakaderera tembiricha corrosion resistance, etc. Mukuvaka kwesimba rakakwirira, kusimba kwepamusoro, hurefu hwepamusoro hwemarefu marefu emafuta uye gasi pombi, iyo simbi chubhu ndiyo. kazhinji hombe dhayamita gobvu madziro akatwasuka musono akanyura arc.Zvinoenderana nezvinopihwa zveiyo API chiyero mumapaipi makuru emafuta uye gasi, apo nzvimbo dzakakwirira, gungwa neguta rine vanhu vakawanda mukirasi 1, 2, musono wakanyura wakanyura arc ndiyo chete yakarongerwa rudzi rwechubhu.

Zvinoenderana nemaitiro ekugadzira akasiyana anogona kukamurwa kuita: UOE/JCOE/HME.Mavhoriyamu e spiral akanyura arc (SSAW) iri munzira ine pakati mutsara wepombi inogadzira Angle (inochinjika), ichigadzira uye welding, iyo welding seam kuita spiral, mukana ndewekuti unogona kugadzira akasiyana siyana esimbi pombi dhayamita ye. kutsanangurwa kwakafanana, raw material range yakakura, weld inogona kudzivirira kushushikana kukuru, mamiriro ekushushikana akanaka, chakashata ndechekuti saizi yakashata yejometri, kureba kweweld kana ichienzaniswa nehurefu hwemusono, nyore kugadzira mitswe, porosity, slag, zvikanganiso zveweld. senge welding, welding stress is tensile stress state.Mitemo uye mirau yeakawanda oiri uye gasi kureba kwepombi dhizaini screw Spiral yakanyura arc inogona kushandiswa chete kumakirasi matatu, kirasi nzvimbo.4 yekune dzimwe nyika iyi nzira ichave yakagadziridzwa mbishi midziyo pachinzvimbo chesimbi ndiro, kuumba uye welding, ipapo welding uye kuonda, kutonhora kuwedzera, mushure mekuputika, iyo welding mhando iri padyo neUOE chubhu, kumba hakuna maitiro akadaro, ndiko kutungamira fekitari yedu kuti ivandudze."West-East gasi" ichiri kushandiswa nekugadzirwa kwechinyakare, iyo chete pombi hole yekuwedzera.IUnited States, Japan neGermany, pane zvose, SSAW yakaipa, haifungi kuti zvakakodzera kushandisa SSAW trunk;Canada neItaly chikamu chinoshandisa SSAW, Russian, shoma shoma yekushandiswa kweSSAW, uye vakaita yakanyanya kuomarara mamiriro ekuwedzera, nekuda kwezvikonzero zvenhoroondo, hunde yakawanda yemumba zvakare ndeye kushandisa SSAW.
