ERW ndeyepamusoro-frequency resistance welding-straight seam welded pombi; LSAW yakanyura arc welding-yakatwasuka musono welded pombi; ese ari maviri ndeemusono seam welded pombi, asi welding process uye kushandiswa kweaviri akasiyana, saka haakwanise kumiririra yakatwasuka seam welded pombi chete. SSAW-spiral welding-spiral welded pipes inowanzoitika.

Musiyano uye kushandiswa kweERW, LSAW uye SSAW mapaipi esimbi

Yakatwasuka musono yakakwira frequency (ERW simbi pombi) yakakamurwa kuita induction welding uye yekubata welding zvinoenderana nenzira dzakasiyana dzewelding. Inoshandisa inopisa-yakakungurutswa yakafara makoiri semidziyo. Mushure mekutanga-kupeta, kuenderera mberi kuumba, welding, kupisa kupisa, gluing, kutwasanudza, kucheka, ine zvakanakira mapfupi welds, yakakwirira dimensional kurongeka, yunifomu yemadziro ukobvu, kunaka kwepamusoro uye kudzvanywa kwepamusoro kuchienzaniswa nemhepo. Zvisinei, kukanganisa ndechokuti mapaipi chete akaonda-akakomberedzwa ane madhayamita maduku uye epakati anogona kugadzirwa. Fusion, groove-like corrosion defects. Nzvimbo dzazvino dzinoshandiswa zvakanyanya igasi rechisikigo mumaguta uye crude oil product transportation.

Yakatwasuka musono yakanyura arc welding (LSAW simbi pombi) inogadzirwa nekushandisa imwe yepakati uye gobvu ndiro seyakagadzirwa, kudzvanya (kutenderedza) ndiro yesimbi muforoma kana muchina wekugadzira, maviri-mativi akanyura arc welding, uye kuwedzera dhayamita. Chigadzirwa chakapedzwa chine huwandu hwakasiyana hwekutsanangurwa, yakanaka weld kusimba, purasitiki, kufanana uye density, uye ine zvakanakira pombi yakakura dhayamita, gobvu pombi madziro, yakakwira dhizaini, kukwirira kwekushisa kwekudzivirira uye kusagadzikana kwekuora. Paunenge uchivaka kusimba kwepamusoro-soro, kusimba kwepamusoro, kwepamusoro-soro kureba kwemafuta uye gasi mapaipi, mapombi esimbi anodiwa anowanzo hombe-dhayamita gobvu-yakavezwa yakatwasuka seam undermerged arc. Zvinoenderana neyakajairwa API, mumapaipi makuru eoiri negasi, kana uchipfuura munzvimbo dzeKirasi 1 neKirasi 2 (senge nzvimbo dzine makomo, nzvimbo dzegungwa, nenzvimbo dzemadhorobha dzine vanhu vakawanda), arc yakanyura yakatwasuka ndiyo yega yakasarudzwa rudzi rwepombi. Zvinoenderana neakasiyana ekuumba nzira, inogona kukamurwa kuita: U0E/JCOE/HME.

Spiral submerged arc welding (SSAW simbi pombi) zvinoreva kuti pakukungurutsa pombi, kutungamira kwayo kumberi kune kona (inochinjika) kune yepakati mutsara wepombi yekugadzira, uye welding inoitwa panguva yekugadzira, uye weld yayo inoumba mutsara unotenderera. Zvakanakira ndezvokuti kutsanangurwa kwakafanana kunogona kuburitsa mapaipi esimbi emadhayamita akasiyana-siyana, zvigadzirwa zvine huwandu hwakawanda hwekuchinjika, weld inogona kudzivirira kushushikana kukuru, uye kushushikana kwakanaka. Izvo zvisingabatsiri ndezvekuti saizi yejometri haina kunaka. Kureba kweweld kwakareba kupfuura kweiyo yakatwasuka seam. Kutsemuka, pores, slag inclusions uye welding kutsauka kunowanzoitika. Nekuremara kwewelding, iyo welding stress iri mu tensile stress state.

Magadzirirwo ezvakajairwa oiri uye gasi mapaipi akareba anoratidza kuti spiral yakanyura arc inogona kushandiswa chete munzvimbo dzeKirasi 3 neKirasi 4. Mushure mekuvandudza maitiro kune dzimwe nyika, zvigadzirwa zvinotsiviwa nemahwendefa esimbi kuti zviparadzanise kuumba uye welding. Mushure me-pre-welding uye nemazvo, iyo welding dhayamita inozowedzera mushure mekutonhora kwemoto. Welding quality iri pedyo neUOE pipe.
Parizvino, hapana maitiro akadaro muChina. Iyi ndiyo nzira yekuvandudza fekitori yedu. Iyo "West-East Gas Transmission" pombi ichiri kugadzirwa maererano nemaitiro echinyakare, asi dhayamita yepombi yekupedzisira yakawedzerwa.
IUnited States, Japan neGermany kazhinji vanoramba kushandisa SSAW uye vanotenda kuti mutsara mukuru haufaniri kushandisa SSAW.
Canada neItaly dzinoshandisa SSAW zvishoma, uye Russia inoshandisa SSAW muhuwandu hudiki. Ivo vakagadzira yakanyanya kuomarara mamiriro ekuwedzera. Nekuda kwezvikonzero zvenhoroondo, mitsetse yakawanda yehunde yemumba ichiri kushandisa SSAW. Iyo mbishi inoshandurwa kuita simbi ndiro kuti iparadzanise kuumba uye welding. Mushure me-pre-welding uye nemazvo, iyo welding dhayamita ichawedzerwa mushure mekutonhora kwemoto. Welding quality iri pedyo neUOE pipe.
ERW yakatwasuka seam welded pombi inowanzo shandiswa sewaya casing muindasitiri yemagetsi. Performance maitiro: 100% ultrasonic bvunzo yemubereki zvinhu inova nechokwadi chemukati mhando yemuviri wepombi; hapana unwinding-disc shearing process, uye zvinhu zvemubereki zvine mapitting mashoma uye makorokoza; iyo pombi yakapedzwa mushure mekushungurudzika kubviswa zvakanyanya haina kusara kunetseka; iyo weld ipfupi uye mukana wekuremara idiki; inogona kutakura ine hunyoro yakavava gasi chaiyo; mushure mekuwedzera kwedhayamita, iyo geometric saizi kurongeka kwepombi yesimbi yakakwirira; welding inoitwa mumutsara wakatwasuka munzvimbo yakachinjika mushure mekunge kuumbwa kwapera, saka kusarongeka, kuvhurwa kwemusono, uye dhayamita yepombi inodzorwa zvakanaka, uye mhando yewelding yakanaka. Chigadzirwa chinoitwa zviyero: API 5L, API 5CT, ASTM, EN10219-2, GB/T9711, 14291-2006 uye mamwe azvino zviyero. Chigadzirwa chesimbi mamakisi anosanganisira: GRB, X42, X52, X60, X65, X70, J55, K55, N80, L80, P110, etc. Zvigadzirwa zvinoshandiswa zvakanyanya mumafuta, gasi rechisikigo, gasi remarasha, migodhi yemarasha, michina, magetsi, kuunganidza uye zvimwe zvinangwa. Yepamberi process tekinoroji michina: senge W-FF kuumba, yakasimba yakakwira-frequency induction welding, ultrasonic flaw yekuona, magineti flux leakage kutadza kuona, uye yakakwirira-yekupedzisira bvunzo zviridzwa: senge metallographic analysis, Vickers hardness tester, maitiro ekuyedza muchina, spectrum analyzer, universal test muchina uye zvimwe zvishandiso. Zvigadzirwa zvinotumirwa kuSouth America, North America, European Union, Southeast Asia nedzimwe nzvimbo. Kwemakore, ivo vakagamuchirwa zvakanaka nevatengi pasi rese.

Kambani yedu inopaEN10210S235JRH, S275JOH, S275J2H, S355JOH,S355J2H, S355K2H, ine zvakatemwa kubva kunze dhayamita 219-1216, kukora kwemadziro 6-40, uye yekutanga fekitori waranti. Vatengi pasi rose vanogamuchirwa kutenga.
