Cov Zoo ntawm Kev Siv Cov Yeeb Nkab Polyurethane Lined Hauv Ob Chav Submerged Arc Welded (DSAW) EN10219 Pipeline Applications

Ua ntej,polyurethane kab yeeb nkabpaub txog nws txoj kev tiv thaiv zoo heev rau kev hnav thiab xeb. Lub polyurethane hauv pem teb ua haujlwm ua ib qho kev tiv thaiv, tiv thaiv sab hauv ntawm cov yeeb nkab kom tsis txhob raug xeb los ntawm cov khoom siv abrasives ntws los ntawm cov yeeb nkab. Qhov no tseem ceeb heev hauv DSAW EN10219 cov yeeb nkab daim ntawv thov vim tias cov yeeb nkab feem ntau raug rau cov kua dej ceev ceev thiab cov khoom khov. Los ntawm kev siv cov yeeb nkab polyurethane, cov tuam txhab tuaj yeem txo qhov zaus ntawm kev saib xyuas thiab kev kho kim, ua rau muaj kev txuag nyiaj ntau hauv lub sijhawm ntev.

Tsis tas li ntawd xwb, cov yeeb nkab polyurethane uas muaj kab muaj qhov yooj ywm thiab ruaj khov dua li lwm cov yeeb nkab. Cov txheej txheem vuam ob chav submerged arc siv los tsim cov yeeb nkab EN10219 ua rau cov yeeb nkab tsis muaj qhov sib txuas thiab muaj zog. Ua ke nrog cov khoom siv polyurethane uas yooj ywm thiab ywj, cov yeeb nkab uas ua tiav tuaj yeem tiv taus qhov kub thiab txias heev thiab cov khoom hnyav, ua rau nws zoo tagnrho rau cov ntawv thov kev lag luam uas xav tau. Qhov kev sib xyaw ua ke ntawm lub zog thiab kev ywj pheej no yog qhov laj thawj tseem ceeb vim li cas cov yeeb nkab polyurethane uas muaj kab yog thawj qhov kev xaiv rau cov ntawv thov yeeb nkab DSAW EN10219.

Ntxiv rau lawv cov khoom siv lub cev, cov kav dej polyurethane-lined kuj tau qhuas rau lawv cov txiaj ntsig ib puag ncig. Polyurethane sab hauv yog inert tshuaj, txhais tau tias nws yuav tsis cuam tshuam nrog cov khoom siv thauj mus los ntawm cov kav dej. Qhov no tsis yog tsuas yog pab tswj qhov huv ntawm cov ntsiab lus, nws kuj tiv thaiv cov tshuaj lom neeg kom tsis txhob raug tso tawm rau hauv ib puag ncig. Thaum cov cai ib puag ncig dhau los ua nruj dua, kev siv cov kav dej polyurethane-lined tuaj yeem pab cov tuam txhab ua kom ntseeg tau tias ua raws li txoj cai thiab txo lawv cov ecological footprint.

Thaum kawg, cov kav dej polyurethane uas muaj kab yog paub txog lawv qhov yooj yim ntawm kev teeb tsa thiab kev saib xyuas. Kev tsim kho tsis muaj kev sib khi ntawm cov kav dej DSAW EN10219 ua ke nrog cov khoom sib dua ntawm polyurethane tso cai rau kev teeb tsa sai thiab yooj yim. Tsis tas li ntawd, qhov chaw du ntawm polyurethane liner txo cov av noo thiab txo kev sib txhuam, ua rau muaj kev ntws zoo dua thiab siv hluav taws xob tsawg dua. Qhov no txhais tau tias cov nqi khiav lag luam qis dua thiab kev tsim khoom ntau dua rau kev ua haujlwm hauv kev lag luam uas vam khom DSAW EN10219 piping.

Hauv kev xaus lus, qhov zoo ntawm cov yeeb nkab polyurethane ua rau nws yog qhov kev xaiv zoo heev rau ob chav submerged arc welded EN10219 yeeb nkab. Lawv txoj kev hnav thiab kev tiv thaiv corrosion, kev ywj pheej thiab kev ruaj khov, kev phooj ywg ib puag ncig, thiab yooj yim ntawm kev teeb tsa thiab kev saib xyuas ua rau lawv yog cov yeeb nkab khoom siv xaiv rau cov chaw ua haujlwm hnyav. Thaum thev naus laus zis txuas ntxiv mus thiab cov qauv kev lag luam hloov pauv, peb xav tias yuav pom kev vam khom ntau ntxiv rau cov yeeb nkab polyurethane hauv xyoo tom ntej.
