ASTM A53 Pipe Standard: Iyo General Use Guide ASTM A53 simbi pombi ndeimwe yeanonyanya kushandiswa zviyero zvepombi dzesimbi munyika mumunda wepombi uye kuvaka. Kune marudzi matatu: LSAW, SSAW, uye ERW, asi maitiro avo ekugadzira akasiyana uye kushandiswa kwakasiyanawo.
1. Astm A53 LSAW Steel Pipe(Longitudinal Submerged arc Welding)
LSAW Pipe inogadzirwa nekupeta ndiro yesimbi kureba yobva yaiswa weld uye musono wakakwenenzverwa uri mukati nekunze kwepombi! Mapaipi eLSAW, ane simbi dzemhando yepamusoro, akanakira kushandiswa kwemafuta epamusoro uye gasi. High simba welds uye madziro akakora anoita kuti pombi idzi dzive dzakakodzera kune yakanyanya kudzvanywa mafuta uye gasi mapaipi, egungwa kunyorera.
2. Astm A53SSAWSimbi Pipe(Spiral Submerged Arc Welded)
Spiral Submerged Arc Welded (SSAW) Pipe inogadzirwa nekushandisa spiral undermerged arc welding method. Maspiral welds avo anogonesa kugadzirwa kwehupfumi uye anoaita akanakira mapombi emvura ari pakati nepakati-kudzika-pasi kana kushandiswa kwezvimiro.
3.Astm A53ERWSimbi Pipe(Electric Resistance Welded)
ERW mapaipi anogadzirwa nemagetsi kuramba welding, kuitira kuti diki radius ye curvature inodiwa pakukotama mukugadzirira weld iyo inobvumira kugadzira mapaipi ane dhayamita diki ane chaiwo welds, mutengo wekugadzira wepombi dzakadaro wakaderera. Iwo anonyanya kushandiswa mukuvaka kwekuvaka mafuremu, mechaniki tubing, uye kutakura zvinwiwa pane yakaderera pressure.
Izvi zvinotevera misiyano mikuru:
Welding Process: LSAW/SSAW maitiro anosanganisira akanyura arc welding, ERW isimba remagetsi rekudzivirira welding process.
Diameter & Kukobvu Kwemadziro: Mapombi eLSAW ane madhayamita akakura ane madziro akakora kana zvichienzaniswa neSSAW neERW mapaipi.
Kubata Kudzvinyirira: LSAW > ERW/SSAW.
