ASTM A53 Pipe Standard: Gwaro Rekushandisa Kwazvo Mapaipi esimbi eASTM A53 ndeimwe yemitemo inoshandiswa zvakanyanya pamapaipi esimbi pasi rose mukugadzira mapaipi nekuvaka. Kune mhando nhatu: LSAW, SSAW, uye ERW, asi maitiro avo ekugadzira akasiyana uye mashandisirwo akasiyanawo.
1. Astm A53 LSAW Simbi Pombi(Kushongedza kwesimbi yakanyudzwa mumvura kwenguva refu)
Pombi yeLSAW inogadzirwa nekukombamisa ndiro yesimbi kureba kwayo wobva wabatanidza uye musono wakabatanidza uri mukati nekunze kwepombi! Mapombi eLSAW, ane simbi dzemhando yepamusoro, akanakira kushandiswa kwemafuta negesi zvine simba guru. Kubatanidza kwakasimba uye madziro akakora zvinoita kuti mapombi aya akwane pamapombi emafuta negesi ane simba guru, pamwe nekushandiswa kwegungwa.
2. Astm A53SSAWPipe yeSimbi(Arc Welded Yakanyudzwa Mumvura)
Mapaipi eSpiral Submerged Arc Welded (SSAW) akagadzirwa uchishandisa nzira yekubatanidza arc inopinzwa nespiral. Mapaipi avo anopinzwa nespiral anogonesa kugadzirwa zvishoma uye anoita kuti akwanise kushandiswa pakugadzira mvura ine simba riri pakati nepakati kusvika pasi kana kushandiswa muchivako.
3.Astm A53ERWPipe yeSimbi(Yakasungirirwa Kudzivirira Magetsi)
Mapaipi eERW anogadzirwa nemagetsi anodzivirira kupwanyika, kuitira kuti nzvimbo diki yekukombama idiwe pakukombama mukugadzirira weld izvo zvinobvumira kugadzira mapaipi ane dhayamita diki ane welds chaiyo, mutengo wekugadzira mapaipi akadaro wakaderera. Anonyanya kushandiswa mukuvaka mafuremu ekuvaka, machubhu emakanika, uye kutakurwa kwemvura nemhepo yakaderera.
Misiyano mikuru ndiyo inotevera:
Maitiro ekushongedzaMaitiro eLSAW/SSAW anosanganisira kusanganisa arc welding pasi pemvura, ERW inzira yekusanganisa electric resistance welding.
Dhayamita & Ukobvu hweMadziro: Mapaipi eLSAW ane dhayamita yakakura ine madziro akakora zvichienzaniswa nemapaipi eSSAW neERW.
Kubata Kumanikidzwa: LSAW > ERW/SSAW.
