Chitoliro cha X42 spiral submerged arc welded, chomwe chimadziwikanso kuti chitoliro chosungunuka cha arc, chimagwiritsidwa ntchito kwambiri ponyamula mafuta, gasi ndi madzi.Mapaipiwa amapangidwa kuti akwaniritse zofunikira za American Petroleum Institute (API) 5L muyezo, womwe umatchula kalasi yachitsulo, makulidwe a khoma ndi zofunikira zaukadaulo zamapaipi achitsulo opanda msoko komanso welded.ZaChitoliro cha X42 SSAW, ntchito polypropylene alimbane chitoliro amapereka angapo ubwino.

Choyamba, chitoliro chokhala ndi polypropylene chimapereka kukana kwa dzimbiri, komwe kumakhala kofunikira kwambiri pamapaipi omwe amakumana ndi zinthu zowononga monga mafuta, gasi ndi mankhwala osiyanasiyana.Ma polypropylene liners amakhala ngati chotchinga choteteza, kuonetsetsa kuti mapaipi azikhala ndi moyo wautali komanso kukhulupirika ngakhale m'malo ovuta.

Kuphatikiza apo, mapaipi okhala ndi polypropylene amadziwikanso ndi kutha kwawo kosalala, komwe kumachepetsa kukangana ndikulola kuti madzi aziyenda bwino.Izi ndizofunikira pamapaipi a X42 SSAW omwe amanyamula mafuta, gasi ndi madzi mtunda wautali.Malo osalala amangochepetsa mphamvu yoyendetsa madzi, komanso imalepheretsa kudzikundikira kwa zinyalala ndi matope mkati mwa chitoliro.

Kuphatikiza pa izi, chitoliro chokhala ndi polypropylene ndi chopepuka komanso chosavuta kuyika, ndikupangitsa kuti ikhale yotsika mtengo pakuyika chitoliro cha X42 SSAW.Kupepuka kwa mapaipiwa kumathandizira kagwiridwe ndi mayendedwe, kuchepetsa nthawi yoyika komanso ndalama zogwirira ntchito.Kuphatikiza apo, kukhazikitsa kosavuta kumatsimikizira kuti nthawi ya polojekiti ikukwaniritsidwa popanda kuchedwa.

ASTM A139 ndiEN10219ndi miyezo iwiri yomwe imatchulidwa kwambiri popanga ndi kuwongolera khalidwe la mipope yachitsulo, kuphatikizapo mapaipi a X42 SSAW.Miyezo iyi imalongosola mawonekedwe amakina, kapangidwe ka mankhwala ndi zofunikira zoyeserera za chitoliro chachitsulo kuti zitsimikizire kuti zikutsatira malamulo amakampani ndi zomwe zimafunikira.Kwa chitoliro chokhala ndi polypropylene, miyeso iyi iyenera kutsatiridwa kuti iwonetsetse kuti ikugwira ntchito komanso yodalirika pakugwiritsa ntchito mapaipi a X42 SSAW.

Mwachidule, chitoliro chokhala ndi mizere ya polypropylene chimakhala ndi gawo lofunikira pakuyika kwa chitoliro cha X42 SSAW, makamaka molingana ndi miyezo ya ASTM A139 ndi EN10219.Kukana kwawo kwa dzimbiri, kutha kwapamwamba, kupepuka kwachilengedwe, komanso kutsata miyezo yamakampani zimawapangitsa kukhala abwino m'mafakitale osiyanasiyana.Pomwe ukadaulo ukupitilirabe patsogolo, mapaipi okhala ndi polypropylene akuyembekezeka kupitilira patsogolo kuti akwaniritse zosowa zamakampani omanga ndi mafuta ndi gasi.
