Mu dziko lomwe likusintha nthawi zonse la ntchito zomangamanga ndi mafakitale, mapaipi achitsulo opanda zingwe akhala chinthu chofunikira kwambiri chifukwa cha magwiridwe antchito awo abwino komanso kudalirika kwawo. Mapaipi awa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, monga petrochemical, kupanga magetsi, ndi kupanga, chifukwa cha kapangidwe kake kopanda zingwe komanso mawonekedwe ake apadera.

TheASTM A335 P5, P9, ndipo mapaipi achitsulo opanda msoko a P11 ndi omwe amafunidwa kwambiri chifukwa cha kukana kutentha kwambiri komanso kupanikizika. Mapaipi amenewa amagwiritsidwa ntchito kwambiri m'mafakitale oyeretsera, m'malo osinthira kutentha, komanso m'malo opangira magetsi, komwe amagwira ntchito yofunika kwambiri ponyamula madzi otentha ndi mpweya mosamala komanso moyenera.

Kumbali inayi, mapaipi opanda msoko a chitsulo cha kaboni, mongaASTM A106ndi machubu a boiler mongaGB 8162 10#, amadziwika ndi ntchito zawo zonse. Mapaipi a ASTM A106 amagwiritsidwa ntchito kwambiri pa ntchito zotsika komanso zapakati monga mapaipi, pomwe GB 8162 10#machubu a boilerAmakondedwa m'mafakitale osiyanasiyana chifukwa amatha kupirira kutentha kwambiri komanso kupsinjika, zomwe zimapangitsa kuti akhale abwino kwambiri poyika ma boiler.

Njira yopangira mapaipiyi popanda kusokoneza imawonjezera mphamvu ya mapaipiwa ndikuchotsa malo ofooka, zomwe zimapangitsa kuti asatuluke mosavuta komanso kuphulika pamene ali ndi mphamvu zambiri. Kuphatikiza apo, mkati mwake mosalala bwino zimathandiza kuti madzi aziyenda bwino, zomwe zimachepetsa kutayika kwa mphamvu panthawi yoyendera.

Pamene kufunikira kwa njira zogwirira ntchito za mapaipi zolimba komanso zogwira mtima kukupitirira kukwera, kugwiritsa ntchito mapaipi achitsulo osapindika a A335 P5, P9, P11, ASTM A106, ndi GB 8162 10# kukukulirakulira m'mafakitale padziko lonse lapansi. Opanga ndi ogwiritsa ntchito onse akuzindikira kufunika kwa mapaipi achitsulo osapindika awa poonetsetsa kuti mapulojekiti awo apambana komanso akhala nthawi yayitali.
