M'dziko lomwe likusintha nthawi zonse la zomangamanga ndi mafakitale, mapaipi achitsulo osasunthika akhala gawo lofunikira kwambiri chifukwa cha magwiridwe antchito ake apadera komanso kudalirika. Mapaipiwa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, monga petrochemical, kupanga magetsi, ndi kupanga, chifukwa cha mawonekedwe awo opanda msoko komanso zinthu zapadera.

TheASTM A335 P5, P9, ndi mapaipi achitsulo a P11 omwe amafunidwa kwambiri omwe amadziwika chifukwa cha kutentha kwambiri komanso kukana kupanikizika. Mipope imeneyi imagwiritsidwa ntchito kwambiri m’malo oyeretsera zinthu, m’zotenthetsera kutentha, ndi m’malo opangira magetsi, kumene amagwira ntchito yofunika kwambiri yonyamula madzi otentha ndi mpweya wabwino.

Komano, mpweya zitsulo Seamless mapaipi, mongaChithunzi cha ASTM A106ndi machubu a boiler ngatiGB 8162 10 #, ndi otchuka chifukwa cha ntchito zawo zonse. Mapaipi a ASTM A106 amagwiritsidwa ntchito kwambiri pamapulogalamu otsika komanso apakatikati ngati mapaipi, pomwe GB 8162 10 #machubu a boileramayamikiridwa m'mafakitale osiyanasiyana chifukwa chotha kupirira kutentha kwambiri komanso kupanikizika, zomwe zimawapangitsa kukhala abwino pakuyika zowotchera.

Kupanga kosasunthika kumapangitsa kuti mapaipiwa azikhala ndi mphamvu komanso amachotsa zofooka, zomwe zimapangitsa kuti asavutike kwambiri ndi kutayikira komanso kuphulika pansi pazovuta kwambiri. Kuphatikiza apo, malo awo osalala amkati amathandizira kuyenda kosasunthika kwamadzimadzi, kumachepetsa kutayika kwa mphamvu panthawi yamayendedwe.

Pamene kufunikira kwa njira zopangira mapaipi okhazikika komanso ogwira mtima kukukulirakulira, kugwiritsa ntchito mapaipi a A335 P5, P9, P11, ASTM A106, ndi GB 8162 10# opanda msoko akuyembekezeka kukula kwambiri m'mafakitale padziko lonse lapansi. Opanga ndi ogwiritsira ntchito mapeto akuzindikira kwambiri kufunika kwa mapaipi opanda zitsulowa pofuna kuonetsetsa kuti ntchito zawo zikuyenda bwino komanso zautali.
