ERW ipombi yakasungirirwa ine musono wepamusoro-soro inopikisa kupinza kwemvura; LSAW ipombi yakasungirirwa ine musono wepamusoro-soro; ese ari maviri ndeemapaipi akasungirirwa ane musono wepamusoro-soro, asi maitiro ekubatanidza nekushandisa maviri acho akasiyana, saka haagoni kumiririra mapaipi akasungirirwa ane musono wepamusoro-soro chete. Mapaipi akasungirirwa ane musono weSSAW-spiral welding-spiral akajairika.

Musiyano nekushandiswa kwemapaipi esimbi eERW, LSAW neSSAW

Mafambiro epamusoro emusono akatwasuka (ERW steel pipe) akakamurwa kuita induction welding uye contact welding zvichienderana nenzira dzakasiyana dzewelding. Inoshandisa hot-rolled wide coils sezvinhu zvekugadzira. Mushure mekukombama, kuumbwa kunoramba kuripo, welding, heat treatment, gluing, straightening, cutting, ine mabhenefiti e welds mapfupi, high dimensional accuracy, ukuru hwemadziro hwakafanana, surface quality yakanaka uye high pressure zvichienzaniswa ne spiral. Zvisinei, dambudziko nderekuti mapaipi matete ane madziro madiki nepakati chete ndiwo anogona kugadzirwa. Fusion, groove-like corrosion defects. Nzvimbo dziri kushandiswa zvakanyanya pari zvino iguta reguta rekutakura gasi rechisikigo nemafuta asina kucheneswa.

Kubatanidza arc yakamanikana yakasungirirwa pasi pemusana (LSAW steel pipe) kunogadzirwa nekushandisa plate imwe chete ine pakati nepakati uye gobvu sezvinhu zvakabikwa, kudzvanya (kumonera) plate yesimbi mumuchina weforoma kana kugadzira, kusanganisa arc yakamanikana yakasungirirwa pasi pemusana ine mativi maviri, uye kuwedzera dhayamita. Chigadzirwa chapedzwa chine zvakawanda zvakatsanangurwa, kusimba kwakanaka kweweld, plasticity, kufanana uye density, uye chine zvakanakira dhayamita yepombi hombe, madziro akakora epombi, kuramba kumanikidzwa kwakanyanya, kuramba kupisa kwakanyanya uye kuramba ngura. Pakuvaka mapaipi emafuta negesi ane simba rakakwirira, kusimba kwakanyanya, emhando yepamusoro, mapaipi esimbi anodiwa anowanzova arc yakamanikana yakasungirirwa pasi pemusana yakamanikana yakasungirirwa pasi pemusana. Zvichienderana neAPI standard, mumapaipi makuru emafuta negesi, kana achipfuura munzvimbo dzeClass 1 neClass 2 (dzakadai senzvimbo dzemakomo, pasi pegungwa, nenzvimbo dzemaguta dzine vanhu vakawanda), arc yakamanikana yakasungirirwa pasi ndiyo yega mhando yemapaipi yakatarwa. Zvichienderana nenzira dzakasiyana dzekugadzira, inogona kukamurwa kuita: U0E/JCOE/HME.

Kubatanidza simbi yeSSAW (Spiral submided arc welding) zvinoreva kuti kana uchitenderedza pombi, divi rayo remberi riri pakona (rinogona kugadziriswa) kumutsetse wepakati wepombi yekugadzira, uye kusanganisa kunoitwa panguva yekuumbwa, uye kusanganisa kwayo kunoumba mutsetse we spiral. Zvakanakira ndezvekuti specification imwechete inogona kugadzira mapaipi esimbi ane dhayamita dzakasiyana, zvinhu zvakagadzirwa zvine mhando dzakasiyana dzekugadzirisa, kusanganisa kunogona kudzivirira kushushikana kukuru, uye kushushikana kwakanaka. Dambudziko nderekuti saizi yejometri haina kunaka. Kureba kwekubatanidza kwakareba kupfuura kwemusono wakatwasuka. Kutsemuka, maburi, slag inclusions uye welding deviations zvinowanzoitika. Kune zvikanganiso zve welding, kusanganisa kwekubatanidza kuri muchimiro chekushushikana kwe tensile.

Magadzirirwo emapaipi emafuta negasi akajairika anotaura kuti arc inonyungudika inotenderera inogona kushandiswa chete munzvimbo dzeClass 3 neClass 4. Mushure mekuvandudza maitiro kunze kwenyika, zvinhu zvakagadziriswa zvinotsiviwa nemaplate esimbi kuti zvive zvakasiyana pakuumba nekusanganisa. Mushure mekusanganisa uye kunyatsoita, dhayamita yekusanganisa ichawedzera mushure mekusanganisa nechando. Hunhu hwekusanganisa hunenge hwakaenzana neUOE pombi.
Parizvino, hapana nzira yakadaro muChina. Iyi ndiyo nzira yekuvandudza fekitari yedu. Pombi ye "West-East Gas Transmission" ichiri kugadzirwa zvichienderana nemaitiro echinyakare, asi dhayamita yemugumo wepombi yakawedzerwa.
United States, Japan neGermany vanowanzoramba kushandisa SSAW uye vanotenda kuti mutsetse mukuru haufanirwe kushandisa SSAW.
Canada neItaly dzinoshandisa SSAW zvishoma, uye Russia inoshandisa SSAW zvishoma. Dzakagadzira mamiriro ekuwedzera akaomarara. Nekuda kwezvikonzero zvekare, mitsetse mizhinji yemumba ichiri kushandisa SSAW. Zvinhu zvakagadziriswa zvinochinjwa kuita simbi kuti zvive zvakasiyana uye zvinosungirirwa. Mushure mekusungirirwa uye kunyatsogadzirwa, dhayamita yekusungirirwa inowedzerwa mushure mekusungirirwa kunotonhora. Hunhu hwekusungirirwa huri pedyo nepaipi yeUOE.
Pombi yeERW straight seam welded inowanzo shandiswa sewaya casing muindasitiri yemagetsi. Hunhu hwekushanda: Kuongororwa kwe100% ultrasonic kwezvinhu zveparent kunovimbisa kunaka kwemukati mepombi; hapana nzira yekuchekerera madhisiki, uye zvinhu zveparent hazvina maburi akawanda uye mavanga mashoma; pombi yakapedzwa mushure mekubvisa kushushikana haina kusimba kwakasara; weld ipfupi uye mukana wekukuvara mudiki; inogona kutakura gasi rechisikigo rakanyorova; mushure mekuwedzera dhayamita, kurongeka kwehukuru hwejometri yepombi yesimbi kwakakwira; welding inoitwa mumutsara wakatwasuka munzvimbo yakatwasuka mushure mekuumbwa kwapera, saka kusarongeka, kuvhurwa kwemusono, uye denderedzwa redhayamita yepombi zvinodzorwa zvakanaka, uye mhando yewelding yakanaka kwazvo. Miyero inogoneka yechigadzirwa: API 5L, API 5CT, ASTM, EN10219-2, GB/T9711, 14291-2006 nedzimwe mwero dzichangoburwa.
