Chitoliro chopangidwa ndi polypropylenelakhala gawo lofunika kwambiri m'mafakitale osiyanasiyana, makamaka m'magawo omanga, mafuta ndi gasi. Mapaipi awa amadziwika chifukwa cha kulimba kwawo kwapadera, kukana dzimbiri, komanso kuthekera kwawo kupirira kutentha kwambiri ndi kupsinjika. Mu blog iyi, tikambirana za kufunika kwa mapaipi okhala ndi polypropylene mu ntchito za mapaipi a X42 SSAW malinga ndiASTM A139ndi miyezo ya EN10219.

Chitoliro cholumikizidwa cha X42 spiral submerged arc welded, chomwe chimadziwikanso kuti chitoliro cholumikizidwa cha arc, chimagwiritsidwa ntchito kwambiri ponyamula mafuta, gasi wachilengedwe ndi madzi. Mapaipiwa amapangidwa kuti akwaniritse zofunikira za muyezo wa American Petroleum Institute (API) 5L, womwe umatchula mtundu wa chitsulo, makulidwe a khoma ndi zofunikira zaukadaulo zamapaipi achitsulo osasendama komanso olumikizidwa.Chitoliro cha X42 SSAW, kugwiritsa ntchito chitoliro chokhala ndi polypropylene kumapereka zabwino zingapo.

Choyamba, chitoliro chopangidwa ndi polypropylene chimapereka kukana dzimbiri bwino, zomwe ndizofunikira kwambiri pakugwiritsa ntchito mapaipi omwe ali ndi zinthu zowononga monga mafuta, gasi wachilengedwe ndi mankhwala osiyanasiyana. Ma polypropylene liners amagwira ntchito ngati chotchinga choteteza, kuonetsetsa kuti mapaipi amakhala nthawi yayitali komanso olimba ngakhale m'malo ovuta.

Kuphatikiza apo, mapaipi okhala ndi polypropylene amadziwikanso ndi mawonekedwe ake osalala, omwe amachepetsa kukangana ndikulola kuyenda bwino kwa madzi. Izi ndizofunikira kwambiri pamapaipi a X42 SSAW omwe amanyamula mafuta, gasi ndi madzi mtunda wautali. Malo osalala samangochepetsa mphamvu yofunikira ponyamula madzi, komanso amaletsa kusonkhanitsa zinyalala ndi matope mkati mwa paipi.

Kuphatikiza pa izi, chitoliro chopangidwa ndi polypropylene ndi chopepuka komanso chosavuta kuyika, zomwe zimapangitsa kuti chikhale njira yotsika mtengo yoyika chitoliro cha X42 SSAW. Kupepuka kwa mapaipi awa kumapangitsa kuti ntchito ndi mayendedwe zikhale zosavuta, kuchepetsa nthawi yoyika ndi ndalama zogwirira ntchito. Kuphatikiza apo, kusavuta kuyiyika kumatsimikizira kuti nthawi ya ntchito ikukwaniritsidwa popanda kuchedwa kulikonse.

ASTM A139 ndiEN10219Ndi miyezo iwiri yomwe imagwiritsidwa ntchito popanga ndi kuwongolera khalidwe la mapaipi achitsulo, kuphatikizapo mapaipi a X42 SSAW. Miyezo iyi imafotokoza za kapangidwe ka makina, kapangidwe ka mankhwala ndi zofunikira pakuyesa mapaipi achitsulo kuti zitsimikizire kuti zikutsatira malamulo ndi zofunikira zamakampani. Pa mapaipi okhala ndi polypropylene, miyezo iyi iyenera kutsatiridwa kuti zitsimikizire kuti ntchito ndi kudalirika kwa mapaipi a X42 SSAW zikuyenda bwino.

Mwachidule, mapaipi okhala ndi polypropylene amagwira ntchito yofunika kwambiri pakugwiritsa ntchito mapaipi a X42 SSAW, makamaka malinga ndi miyezo ya ASTM A139 ndi EN10219. Kukana kwawo dzimbiri, kusalala kwa pamwamba, kupepuka, komanso kutsatira miyezo yamakampani kumapangitsa kuti akhale abwino kwambiri m'mafakitale osiyanasiyana. Pamene ukadaulo ukupitilira kupita patsogolo, mapaipi okhala ndi polypropylene akuyembekezeka kupangidwanso kuti akwaniritse zosowa zosintha zamakampani omanga ndi mafuta ndi gasi.
