ERW igetsi-kupikisa welded simbi pombi, Resistance welded simbi pombi inokamurwa kuchinjanisa welded simbi pombi uye DC welded simbi pombi mumhando mbiri.

AC welding zvinoenderana nemafrequency akasiyana akakamurwa kuita yakaderera-frequency welding, IF welding, welding yeUltra-IF uye high-frequency welding. High-frequency welding inonyanya kushandiswa kugadzirwa kwepombi-yakavezwa simbi pombi kana madziro ukobvu simbi pombi, yakakwira frequency welding mukubata welding uye induction welding. DC welding inowanzoshandiswa kune diki-diameter simbi pombi. Saka, maererano nehupamhi, yepamusoro-frequency welded pombi inosanganisirwa muERW pombi i-high-frequency welding process kugadzira mapaipi eERW. ERW Longitudinal advanced product performance mumunda wemafuta uye gasi kuchengetedza uye chekufambisa, hutungamiriri hwemhando yepamusoro, yakawanda yehupfumi simbi pombi.

SAW simbi mapaipi ipfupi ne Submerged Arc Welding Steel Pipe, iko kushandisa yakanyura arc soldering process kugadzira simbi, iyo nzira inoburitsa yakanyanya kusimba yazvino density, iyo flux layer yekudzivirira kukurumidza kurasikirwa kwekupisa, uye yakanyura mukati. welding region. Yakanyura arc weld yemhando yepamusoro, kugadzirwa kwepamusoro, arc uye utsi hunhu hushoma hwekunyudzwa kwearc welded pombi inoshandiswa zvakanyanya mumidziyo yekumanikidza, kugadzira pombi, matanda, kuderera kwemvura, simbi inoshanda. Zvigadzirwa zvikuru zveSAW simbi mapaipi LSAW Simbi Pipe, Longitudinally Submerged Arc Welding Steel Pipe LSAW simbi pombi, iko kushandiswa kweakanyudza arc welding kugadzirwa kweyakatwasuka seam simbi pombi.

Musiyano pakatierwuyeakaonapombi yesimbi

Sezvo ERW simbi mutopota uye SAW simbi nyere mupombi panguva kuumba, nomoto uye kwacho kwakasiyana, kuti mhando mbiri simbi nyere mukuita pane zvimwe kusiyana.

(1) ERW simbi pombi pamusoro pemhando yepamusoro kune spiral yakanyura arc welded pombi, ERW simbi pombi pamusoro inotsvedzerera, yakatsetseka, yakanaka, SAW simbi pombi yemukati uye yekunze weld kusimbiswa.

(2) ERW simbi pombi weld defect marudzi ishoma pane saha simbi pombi. Saw simbi pombi ine solvent yakaiswa, mamwe marudzi akaremara, kuwedzera vhoriyamu kuremara, pane waya-mutsara musungo. ERW simbi pombi weld kukanganisa chete waya-mutsara uye yakatwasuka welds, iyo yekuongorora maitiro iri nyore kutevedzera, uye zvikanganiso mukunyanya kuratidzwa panguva, kamwe kushaikwa kweyakajeka, ultrasonic inoratidzira yakasimba, iri nyore kuona.

(3) ERW simbi pombi chokuita saw simbi pombi mune residual stress reshiyo yakaderera. Sezvo ERW pombi deformation mukuita deformation zvakazara, yakasanganiswa inotevera saizi yakafuratira oval, elliptical vertical shanduko uye mitsipa, zvichiita kuti ERW pombi yakasara kushushikana inove idiki. Kuongororwa kwepanyama kwakaratidza kuti kutsanangurwa kwakafanana, chinhu chimwe chete ERW pombi mushure mekuchekwa pamwe neaxis, axial uye transverse incisions kudiki kutama pane spiral yakanyura arc welded pombi.

(4) ERW Pipe kuita kwese kwakafanana, kana pombi ikave yakaremara, simbi yakaraswa kutonga, inobvumira welding. SAW simbi pombi inobvumirwa, uye pombi welding kuita uye kuita kwese hakuna kuenderana, nzvimbo yewelding inokonzeresa kukanganisa ngura. Miedzo inoratidza kuti kushushikana kukungura kuneta bvunzo ERW pombi spiral yakanyura arc welded pombi kureba kupfuura hupenyu.
