Pombi yesimbi yeERW
Pombi yeERW (pombi yemagetsi inodzivirirwa nemagetsi) uye pombi yeCDW (pombi yesimbi inodhonzwa inotonhora) inzira mbiri dzakasiyana dzekugadzira pombi dzesimbi dzakasungirirwa.
1. Maitiro ekugadzira
| Zvinhu zvekuenzanisa | Pombi yeERW (pombi yakasungirirwa inodzivirirwa nemagetsi) | Pombi yeCDW (pombi yakasungirirwa inotonhorera) |
| Zita rizere | Kuramba Kwemagetsi Welded Pipe | Yakadhonzwa Inotonhora Welded Pipe |
| Maitiro ekuumba | Mupendero weplate yesimbi unodziiswa nemagetsi epamusoro-soro uye unomanikidzwa uye unosungirirwa kuita chimiro | Kutanga yakabatanidzwa mumapombi, yozotorwa nechando (kurapwa kwekuchinja kwechando) |
| Nzira yekushongedza | Kuwedera Kwekudzivirira Kuramba Kukuru (HFW/ERW) | ERW kana argon arc welding (TIG) inowanzo shandiswa pakuwedera |
| Kugadziriswa kunotevera | Kuyera saizi nekucheka zvakananga mushure mekushongedza | Kudhirowa kunotonhora (kutenderedza kunotonhora) kupedzisa mushure mekushongedza |
2. Hunhu hwekushanda
Pombi yeERW
Kururama kwehukuru: Zvose (± 0.5% ~ 1% kukwirira kwedhayamita yekunze)
Hunhu hwepamusoro: Weld iri pachena zvishoma uye inoda kukweshwa
Hunhu hwemakanika: Simba rinoenderana nechinhu chikuru, uye panogona kunge paine kupfava munzvimbo yekunamira
Kushushikana kwasara: Kwakaderera (kurapwa kupisa kuri nyore chete mushure mekunamira)
Pombi yeCDW
Kururama kwehukuru: kwakakwirira zvikuru (mukati me ± 0.1mm, kwakakodzera zvinangwa zvekururama)
Hunhu hwepamusoro: pamusoro wakatsetseka, hapana chiyero che oxide (yakakweshwa mushure mekudhirowa kutonhora)
Hunhu hwemakanika: kuomarara kwekushanda kunotonhora, simba rakawedzerwa ne20% ~ 30%
Kushushikana kwasara: kwakanyanya (kunongedza kunodiwa kuti ubvise kushushikana kwekukweva kunotonhora)
3. Mamiriro ekushandisa
ERW: mapaipi emafuta/gasi, mapaipi ekuvaka (scaffolding), mapaipi emvura ane simba shoma (GB/T 3091)
CDW: masirinda ehydraulic, zvikamu zvemakanika zvine hungwaru (zvakadai semabhegi ekutakura), shaft dzekutumira mota (nzvimbo dzine zvinodiwa zvehupamhi hwepamusoro)
Mipimo yakafanana yemhando
ERW: API 5L (pombi yemapaipi), ASTM A53 (pombi yekuvaka), EN 10219 (pombi yakasungirirwa yeEuropean standard)
CDW: ASTM A519 (pombi inodhonzwa inotonhora nemazvo), DIN 2391 (pombi yekuGerman ine magadzirirwo akakwirira)
Pombi yeCDW = pombi yeERW + kudhirowa kunotonhora, ine saizi dzakanyatsojeka uye simba rakakwirira, asiwo mitengo yakakwira.
Pombi yeERW yakakodzera kushandiswa pakuvaka, nepo pombi yeCDW ichishandiswa mumichina yakanyatsogadzirwa.
Kana mashandiro epaipi yeCDW achida kuvandudzwa zvakanyanya, mushonga we annealing unogona kuwedzerwa (kubvisa kushushikana kwekushanda kunotonhora).
Nguva yekutumira: Kubvumbi-01-2025
