Ubwino Wogwiritsa Ntchito Chitoliro Chokhala Ndi Mizere Ya Polyurethane Mu Arc Welded (DSAW) EN10219 Pipeline Applications

Choyamba,chitoliro chopangidwa ndi polyurethaneamadziwika chifukwa chokana kwambiri kuvala ndi dzimbiri.Chingwe cha polyurethane chimagwira ntchito ngati chotchinga choteteza, chomwe chimalepheretsa mkati mwa chitoliro kuti chisawonongeke ndi abrasives omwe akuyenda mupaipi.Izi ndizofunikira kwambiri pakugwiritsa ntchito mapaipi a DSAW EN10219 popeza mapaipi nthawi zambiri amakhala ndi madzi othamanga kwambiri komanso tinthu tolimba.Pogwiritsa ntchito mapaipi okhala ndi polyurethane, makampani amatha kuchepetsa nthawi yokonza ndi kukonza zodula, zomwe zimapangitsa kuti pakhale ndalama zambiri zowononga nthawi yayitali.

Kuphatikiza apo, chitoliro chokhala ndi polyurethane chimapereka kusinthasintha kwapamwamba komanso kulimba poyerekeza ndi zida zina zapaipi.Njira yowotcherera ya arc yomizidwa kawiri yomwe imagwiritsidwa ntchito popanga mapaipi a EN10219 imapangitsa kuti paipi ikhale yopanda msoko komanso yamphamvu kwambiri.Kuphatikizidwa ndi zinthu zosinthika komanso zotanuka za polyurethane, makina opangira mapaipi amatha kupirira kutentha kwambiri komanso katundu wolemetsa, ndikupangitsa kuti ikhale yabwino pantchito zamafakitale.Kuphatikizika kwa mphamvu ndi kusinthasintha kumeneku ndi chifukwa chachikulu chomwe chitoliro chokhala ndi polyurethane chili chisankho choyamba pakugwiritsa ntchito mapaipi a DSAW EN10219.

Kuphatikiza pa mawonekedwe awo akuthupi, mapaipi okhala ndi polyurethane amayamikiridwanso chifukwa cha chilengedwe.Polyurethane lining ndi inert mankhwala, kutanthauza kuti sangachite ndi zinthu kunyamulidwa kudzera mapaipi.Sikuti izi zimathandiza kusunga chiyero cha zomwe zili mkati, komanso zimalepheretsa kuti zinthu zovulaza zisatulutsidwe m'chilengedwe.Pamene malamulo a chilengedwe akuchulukirachulukira, kugwiritsa ntchito mapaipi okhala ndi polyurethane kungathandize makampani kuonetsetsa kuti akutsatira ndikuchepetsa momwe chilengedwe chimakhalira.

Pomaliza, mapaipi okhala ndi polyurethane amadziwika chifukwa chosavuta kukhazikitsa ndi kukonza.Kumanga kopanda msoko kwa mapaipi a DSAW EN10219 ophatikizidwa ndi zinthu zopepuka za polyurethane zimalola kuyika mwachangu komanso kosavuta.Kuphatikiza apo, mkati mwa liner ya polyurethane liner yosalala imachepetsa kuchulukana kwa dothi ndikuchepetsa kugundana, zomwe zimapangitsa kuyenda bwino komanso kugwiritsa ntchito mphamvu pang'ono.Izi zikutanthauza kutsika kwa ndalama zogwirira ntchito komanso zokolola zambiri zamafakitale kudalira DSAW EN10219 mapaipi.

Mwachidule, ubwino wa chitoliro chopangidwa ndi polyurethane chimapangitsa kukhala chisankho chabwino kwambiri pazitsulo zomizidwa ndi madzi arc welded EN10219.Mavalidwe awo ndi kukana kwa dzimbiri, kusinthasintha komanso kukhazikika, kuyanjana ndi chilengedwe, komanso kuyika bwino ndikuwongolera kumawapangitsa kukhala chitoliro chosankha m'malo ovuta a mafakitale.Pamene luso lamakono likupitilila patsogolo komanso miyezo yamakampani ikupita patsogolo, tikuyembekeza kuwona kudalira kwambiri mapaipi okhala ndi polyurethane m'zaka zikubwerazi.
