Spiral Welded Pipes Rau Natural Gas Pipelines
Kauv welded yeeb nkab, tseem hu uacevvuam, yog tsim los siv cov cuab yeej siv vuam zoo los tsim cov khoom muaj zog. Nws muaj qhov txuas txuas txuas txuas ntxiv uas tsim los ntawm kev sib txuas welding steel strips ua ke. Cov qauv tshwj xeeb no muab lub zog tsis sib xws, ua rau nws zoo tagnrho rau kev thov kev siv xws linatural gas kab.
Ib qho ntawm cov kev siv tseem ceeb ntawm kauv welded yeeb nkab yog kev thauj mus los ntawm cov pa roj. Nws yog tsim tshwj xeeb thiab tsim los tiv thaiv cov kev kub ntxhov ib puag ncig cuam tshuam nrog kev sib kis ntawm cov pa roj. Kauv welded kav ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig ntawm kev xa khoom ntawm cov pa roj mus rau kev lag luam thiab cov neeg siv khoom, ua kom muaj kev ntseeg siab thiab txo qis qhov muaj peev xwm xau lossis xwm txheej.

Ntxiv rau,kauv welded kavkuj tau siv dav hauv cov dej thiab cov kav dej. Nws cov khoom siv pov thawj thiab corrosion kuj ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev thauj dej los ntawm qhov chaw mus rau qhov chaw. Vim nws cov kav ntev, nws tuaj yeem tiv taus cov xwm txheej hnyav uas feem ntau ntsib hauv cov dej num, muab cov zej zog thiab kev lag luam nrog cov kev daws teeb meem ntev, txhim khu kev qha.
Hauv kev lag luam petrochemical, kauv welded kav ua lub luag haujlwm tseem ceeb hauv kev thauj mus los ntawm cov pa roj, nkev, roj liquefied roj av thiab lwm yam khoom siv. Nws lub zog siab thiab corrosion kuj ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau kev xa cov ntaub ntawv tsis zoo no. Txawm hais tias nws yog cov cog cog petrochemical loj lossis kev teeb tsa me me, cov kav dej welded kav kom muaj kev nyab xeeb thiab muaj txiaj ntsig kev thauj mus los ntawm cov peev txheej tseem ceeb no.
Ntxiv mus, cov qauv ntawm kauv welded yeeb nkab yog dav siv. Nws feem ntau yog siv los ua piling raj rau cov hauv paus hauv kev tsim kho, muab kev txhawb nqa tsim nyog thiab ruaj khov. Cov yeeb nkab txoj kev ruaj khov kuj ua rau nws xaiv thawj zaug rau cov txuas hniav, cov chaw nres nkoj, txoj kev thiab cov qauv tsim. Lawv muaj peev xwm tiv taus cov khoom hnyav thiab sab nraud ua kom muaj kev nyab xeeb thiab kev ncaj ncees ntawm cov qauv no, ua rau lawv yog ib qho tseem ceeb ntawm kev tsim kho hauv nroog.
Nyob rau hauv xaus, kauv welded yeeb nkab (tseem hu ua yeeb nkab weld) muab ib tug ntau yam thiab check tov rau ntau yam lag luam thiab sectors. Nws muaj ntau yam kev siv xws li dej engineering, petrochemical kev lag luam, tshuaj lom neeg kev lag luam, hluav taws xob fais fab kev lag luam, kev ua liaj ua teb irrigation, kev tsim kho hauv nroog, thiab lwm yam. Txawm hais tias siv rau kev thauj mus los ntawm cov kua los yog gases, los yog rau cov hom phiaj, kauv welded yeeb nkab yog ib qho kev xaiv zoo thiab muaj txiaj ntsig. Nrog nws lub zog tshwj xeeb, elasticity thiab corrosion kuj, nws tseem yog ib qho tseem ceeb hauv kev lag luam niaj hnub.
