Zolumikizira za mapaipi a ASTM A234 WPB & WPC kuphatikiza zigongono, tee, zochepetsera

Kufotokozera Kwachidule:

Chikalatachi chikukhudza zitsulo zophikidwa ndi kaboni ndi zitsulo zosungunula zopangidwa ndi zitsulo zopanda chitsulo komanso zosungunula. Zipangizozi zimagwiritsidwa ntchito popanga mapaipi opanikizika komanso popanga zotengera zopanikizika kuti zigwiritsidwe ntchito kutentha kwapakati komanso kokwera. Zipangizo zolumikizira ziyenera kukhala ndi chitsulo chophedwa, zosungunula, mipiringidzo, mbale, zinthu zosungunula zopanda chitsulo kapena zosungunula zokhala ndi chitsulo chodzaza. Ntchito zosungunula kapena zopanga zitha kuchitidwa pomenya, kukanikiza, kuboola, kutulutsa, kusokoneza, kupindika, kupindika, kusakaniza, kusakaniza, kupangira, kapena kuphatikiza ntchito ziwiri kapena zingapo. Njira yopangira iyenera kugwiritsidwa ntchito kotero kuti sipanga zolakwika zovulaza m'zosungunula. Zipangizo, zikapangidwa kutentha kokwera, ziyenera kuziziritsidwa kutentha kochepera pamlingo wofunikira pansi pa mikhalidwe yoyenera kuti zipewe zolakwika zovulaza zomwe zimachitika chifukwa cha kuzizira mwachangu kwambiri, koma osati mwachangu kuposa liwiro lozizira mumlengalenga wodekha. Zipangizozi ziyenera kuyesedwa mwamphamvu, kuyesedwa kuuma, ndi kuyesedwa kwa hydrostatic.

Kupanga

Zolumikizira za ASTM A234 zachitsulo cha kaboni zitha kupangidwa kuchokera ku mapaipi osalumikizana, mapaipi olumikizidwa kapena mbale pokonza ntchito zokanikiza, kuboola, kutulutsa, kupinda, kusakaniza kuwotcherera, kukonza, kapena kuphatikiza ntchito ziwiri kapena zingapo izi. Zolumikizira zonse kuphatikiza zolumikizira muzinthu zamachubu zomwe zolumikizira zimapangidwa ziyenera kupangidwa motsatira ASME Section IX. Kuchiza kutentha pambuyo pa kuwotcherera pa 1100 mpaka 1250°F[595 mpaka 675°C] ndikuwunika kwa x-ray kuyenera kuchitidwa pambuyo pa njira yowotcherera.
