API 5L Welded Steel Pipe Manufacturing Process
Type 1. Spiral Welded: Spiral welded simbi mapaipianogadzirwa ne spiral welding tambo yesimbi, ichiita helical seam. Iyi nzira inobvumira kugadzirwa kwemapaipi makuru edhayamita uye kazhinji inodhura-inoshanda kune mamwe maapplication.
Coating uye Kurapa:Kuwedzera kusadzivirirwa nekusimba uye kusimba, mapaipi aya anogona kuita nzira dzakasiyana dzekupfeka uye kurapwa, senge fusion bonded epoxy (FBE) kana matatu-layer polyethylene (3LPE) machira.
Rudzi rwechipiri. Magetsi Resistance Welding (ERW):Micheto yesimbi yakagadzirwa nesimbi inopisa nemagetsi. Dzvinyiriro inozoiswa kuumba mipendero pamwe chete, kugadzira yakasimba-state weld pasina kudiwa kwezvinhu zvekuzadza.
Type 3.Longitudinal Welding:
Submerged Arc Welding (SAW): Micheto yepombi yakaumbwa inobatanidzwa pamwe chete uchishandisa iyo yakadzika arc welding process, iyo inosanganisira kushandiswa kwemagetsi arc uye granular flux kugadzira yakakwirira-mhando, yakasimba weld.
Kaviri Submerged Arc Welding (DSAW): Pamapombi akakora, ese ari mukati nekunze seams akaiswa weld, kuve nechokwadi chekupinda uye kusimba.
