Kufunika kwa ASTM A139 Pakumanga Mapaipi Apansi Pansi pa Gasi Wachilengedwe
Spiral welded carbon steel pipe yopangidwa kutiASTM A139idapangidwa makamaka kuti igwiritse ntchito mobisa monga kutumiza ndi kugawa gasi.Mapaipiwa amapangidwa pogwiritsa ntchito njira yowotcherera yapadera yomwe imapanga zolumikizira zolimba komanso zolimba, zomwe ndizofunikira kwambiri kuti athe kulimbana ndi zovuta zapansi panthaka komanso zachilengedwe zomwe mapaipiwa adzatsatiridwa.

Njira yowotcherera yozungulira yomwe imagwiritsidwa ntchito mu ASTM A139 imapangitsa chitoliro kukhala chokhazikika komanso chosalala mkati, chomwe ndi chofunikira kwambiri kuti gasi wachilengedwe ayende bwino kudzera mupaipi.Mipopeyi imapezekanso mumitundu yosiyanasiyana ndi makulidwe a khoma, zomwe zimalola kusinthasintha kwa mapangidwe ndi zomangamanga kuti zigwirizane ndi zofunikira zenizeni za kayendedwe ka gasi kapena kugawa.
Kuphatikiza pa kudalirika komanso kulimba, chitoliro cha ASTM A139 chimapereka kukana kwa dzimbiri, zomwe ndizofunikira kwambiri pakuwonetsetsa kuti mapaipi a gasi apansi panthaka akuyenda bwino.Chitsulo cha kaboni chomwe chimagwiritsidwa ntchito m'mapaipiwa ndi opangidwa mwapadera kuti asachite dzimbiri, kuwonetsetsa kuti mapaipi azikhala osasunthika komanso osatayikira kwazaka zikubwerazi.
Chitetezo ndichofunika kwambiri pomanga mapaipi a gasi apansi panthaka.Mapaipi a ASTM A139 amapangidwa ndikuyesedwa kuti azitsatira miyezo yolimba yamakampani ndi mafotokozedwe, kuwonetsetsa kuti atha kupirira zovuta zapadera zamagwiritsidwe ntchito mobisa.Izi zimapereka zida zamagesi zachilengedwe, owongolera komanso mtendere wamalingaliro pagulu podziwa kuti zida zomwe zimatulutsa gasi ndizodalirika komanso zotetezeka.
Pomaliza, ASTM A139spiral welded carbon steel pipeimathandiza kwambiri pomanga mapaipi a gasi apansi panthaka.Kukhalitsa kwawo, kukana kwa dzimbiri komanso kutsata miyezo yamakampani kumawapangitsa kukhala abwino pama projekiti ofunikira ngati awa.Zikafika pakuwonetsetsa chitetezo, kudalirika, komanso kuyendetsa bwino njira zotumizira ndi kugawa gasi, kugwiritsa ntchito mapaipi a ASTM A139 ndi chisankho chomwe sichinganyalanyazidwe.Posankha zipangizo zoyenera zogwiritsira ntchito pansi pa nthaka, tingathe kuonetsetsa kuti zipangizo zathu za gasi zachilengedwe zimakhala zotetezeka komanso zodalirika kwa mibadwo yotsatira.
