API 5L Welded Steel Yeeb Nkab Txheej Txheem
Hom 1. Kauv Welded: Kauv welded steel kavyog tsim los ntawm spirally welding ib sawb ntawm hlau, ua ib tug helical seam. Cov txheej txheem no tso cai rau kev tsim cov kav dej loj thiab feem ntau siv nyiaj ntau dua rau qee yam kev siv.
Txheej thiab Kev Kho Mob:Txhawm rau txhim kho kev tiv thaiv corrosion thiab ua haujlwm ntev, cov kav dej no yuav dhau los ua ntau yam txheej txheem txheej txheem thiab kev kho mob, xws li fusion bonded epoxy (FBE) lossis peb txheej polyethylene (3LPE) txheej.
Hom 2. Kev Siv Hluav Taws Xob Hluav Taws Xob (ERW):Cov npoo ntawm cov hlau tsim yog rhuab siv hluav taws xob tsis kam. Tom qab ntawd lub siab yog siv los tsim cov npoo ua ke, tsim kom muaj cov khoom siv hauv lub xeev tsis tas yuav tsum tau muab cov khoom ntim.
Hom 3.Longitudinal Vuam:
Submerged Arc Vuam (SAW): Cov npoo ntawm cov yeeb nkab tsim tau welded ua ke siv cov txheej txheem submerged arc vuam, uas suav nrog kev siv hluav taws xob arc thiab granular flux los tsim cov khoom zoo, muaj zog vuam.
Ob chav Submerged Arc Vuam (DSAW): Rau cov kav dej tuab, ob qho tib si sab hauv thiab sab nraud yog welded, ua kom tiav kev nkag mus thiab lub zog.
