Kufunika kwa ASTM A139 Pakumanga Mapaipi Apansi Pansi pa Gasi Wachilengedwe

Kufotokozera Kwachidule:

Popanga mapaipi a gasi apansi panthaka, ndikofunikira kugwiritsa ntchito zida zoyenera kuti zitsimikizire chitetezo, kulimba, komanso kuchita bwino.Chinthu chimodzi chomwe chimagwiritsidwa ntchito popanga mizere yamafuta awa ndi ASTM A139, yomwe ndi muyezo wapaipi yachitsulo yozungulira yozungulira.Mu blog iyi, tiwona kufunikira kwa ASTM A139 pakumanga mapaipi achilengedwe apansi panthaka komanso momwe imagwirira ntchito yofunika kwambiri pakuwonetsetsa kukhulupirika ndi kudalirika kwa magawo ofunikirawa.

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.
