X42 SSAW Pipe Spiral Welded Tube
suma:
Mumunda wepombi dzesimbi, dzakasiyana-siyana welding matekiniki anoshandiswa kuti uwane yakakwirira-mhando uye yakavimbika kubatana.Imwe nzira yakadarospiral undermerged arc welding(SAW), iyo inoita basa rinokosha mukugadzirwa kwe X42 SSAW pombi.Semutungamiri weindasitiri, Cangzhou Spiral Steel Pipe Group Co., Ltd., inozivikanwa nerudzi rwayo rweWuzhou, inoteedzera zviyero zvepasi rose uye inoona kuti zvigadzirwa zvayo (kusanganisira X42 spiral yakanyudzwa arc welded pombi) zvinosangana neAPI Spec 5L, ASTM A139, ASTM A252. uye EN 10219. Mubhuku rino tinoongorora nyika inonakidza yeX42 SSAW pombi, tichiratidza zvakanakira kushandisa spiral undermerged arc welding mukugadzira spiral welded pipe.
Dzidza nezve Spiral Submerged Arc Welding (SAW):
Spiral submerged arc welding, inozivikanwawo seSAW, inyanzvi yekukwedha nzira inoshandiswa kugadzira pombi dzakashongedzerwa senge.X42 SSAW pombi.Iyo tekinoroji inosanganisira kunyungudutsa waya uye simbi yepasi uchishandisa kupisa kunogadzirwa nekupisa kwearc pakati pewaya uye kuyerera pasi peiyo flux layer.Iyo flux layer inoshanda sechidziviriro chinodzivirira, ichidzivirira kusvibiswa kwemuchadenga kubva mukukanganisa maitiro ekutengesa.Iyi nzira ine mabhenefiti akati wandei pane mamwe mawelding matekiniki.

Zvakanakira zve spiral undermerged arc welding:
1. Inopindirana uye yemhando yepamusoro welds: Iyo nzira yeSAW inoshandiswa muX42 SSAW pombi inobereka yunifomu uye yepamusoro welds.Kana iyo arc ichinyudzwa mukuyerera, inogadzira nzvimbo inodzorwa inodzivirira nzvimbo ye soldering kubva kune ekunze zvinhu, kuve nechokwadi kuti inowirirana uye yakavimbika majoini.Izvi zvinoita kuti pave ne spiral welded pombi dzine simba rinoshamisa uye nekusimba.
2. Kuwedzera kushanda zvakanaka: Spiral submerged arc welding inopa kukosha kwakakosha nekuda kwemaitiro ayo otomatiki.Maitiro acho anosanganisira kuenderera, kudyisa otomatiki kwewaya yewelding, zvichikonzera kukurumidza kugadzirwa uku uchichengeta chaiyo.Mateisheni epamusoro uye kutsamira kushoma pabasa remawoko kunobatsira pakubudirira uye kuita mari.
3. Inokodzera kushandiswa kwakasiyana-siyana: X42 SSAW pombi inogadzirwa ne spiral submerged arc welding inoshandiswa zvakanyanya mumaindasitiri akawanda.Mapombi aya anoshandiswa mukufambisa oiri negasi, mapaipi emvura, kuvaka tsigiro yezvimiro, kuunganidza nheyo, nezvimwe.Iko kuita kwakasiyana-siyana uye kuvimbika kweiyo X42 SSAW chubhu inoita kuti ive yakanaka kune yakakosha maapplication.
4. Kuvandudzwa kwema mechanical properties: Nzira yeSAW inochengetedza zviri nani kutonga kwemagetsi emagetsi panguva yekugadzirwa kwe X42 spiral undermerged arc welded pipes.Kudzora uku kunogona kukwidziridza zvimiro zvemuchina, kusanganisira kuomarara kwesimba, goho simba uye kusimba kwesimba.Nekuda kweizvozvo, mapaipi aya ane kupikisa kwakanyanya kumasimba ekunze uye akakodzera kunyange kune dzakaoma nharaunda.
Mukupedzisa:
Kana isu tichiongorora nyika yespiral yakanyudzwa arc welding muX42 SSAW pombi kugadzirwa, zvinova pachena kuti sei nzira iyi ichishandiswa zvakanyanya muindasitiri yesimbi.Spiral undermerged arc welding inopa akawanda mabhenefiti akadai seanopindirana weld seams, kuwedzera kushanda zvakanaka, kuita zvakasiyana-siyana uye yakagadziridzwa michina zvivakwa, kuve nechokwadi chekuti mapombi akaiswa welded, senge X42 SSAW mapaipi esimbi anogadzirwa neCangzhou Spiral Steel Pipe Group Co., Ltd., anosangana nepamusoro-soro maitiro ehutano.Naizvozvo, maererano nekuvimbika, kusimba uye kuita, iyo X42 SSAW chubhu inoratidza kuva yakanakisa sarudzo kune dzakasiyana siyana dzekushandisa mumaindasitiri.
