Roj casing thiab tubing yog qhov tseem ceeb ntawm cov roj kev lag luam, thiab lawv cov txheej txheem ntau lawm yog ua kom nruj thiab ua tiav. Hauv qab no, peb yuav tshuaj xyuas cov txheej txheem ntau ntxiv los ntawm kauj ruam.
1. Khoom npaj npaj
Thawj kauj ruam hauv kev ua cov roj uas muaj nuj nqis thiab tubing yog los npaj cov ntaub ntawv tsim nyog. High -} Cov hlau zoo yog xaiv raws li cov khoom siv hauv paus kom ntseeg tau lub zog zoo thiab corrosion tsis kam. Cov hlau undergoes nyuaj kev soj ntsuam thiab tshuaj ntsuam xyuas kom meej nws ua tau raws cov qauv tsim khoom.
2. Ua thiab kev sib sau
Ua thiab kev sib sau yog cov kauj ruam tseem ceeb hauv roj casing thiab tubing ntau lawm. Thaum lub sijhawm cov txheej txheem no, cov steel undergoes muaj cov txheej txheem xws li kev txiav, khoov, thiab maj mam sib sau ua lub tubing daim ntawv pib. Kev tswj nruj ua nruj ntawm ntau yam tsis yog thaum lub sijhawm ua kom ntseeg tau cov khoom precision thiab zoo.
3. Kev kho cua sov
Kev kho cua sov yog qhov tseem ceeb heev rau kev txhim kho cov khoom siv tshuab thiab corrosion tiv taus cov roj casing thiab tubing. Cov txheej txheem cua sov xws li quenching thiab tempering tuaj yeem kho cov khoom siv sab hauv, ua rau cov khoom zoo dua qub.
4. Nto Kho
Kev kho deg yog qhov tseem ceeb kom txhim kho cov corrosion tiv taus thiab kev pabcuam lub neej ntawm cov roj casing thiab tubing. Cov txheej txheem kho cov txheej txheem xws li galvanizing thiab tha xim, uas tuaj yeem ua kom zoo cais cov roj sab nraud los ntawm kev sib chwv roj, yog li txo qhov kev pheej hmoo ntawm corrosion.
