Mapaipi achitsulo okhala ndi ma flanges osakanikirana ndi mtundu wa chitoliro chomwe chimagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza madzi, zimbudzi, ndi mapaipi a mafakitale.Mapaipiwa amapangidwa kuchokera ku chitsulo cha ductile, chomwe ndi mtundu wa chitsulo chonyezimira chomwe chawonjezera mphamvu ndi ductility.
The integrally cast flange ndi gawo la chitoliro chomwe chimaponyedwa ngati chidutswa chimodzi ndi thupi la chitoliro.Izi zikutanthauza kuti flange si chigawo chosiyana chomwe chimawotchedwa kapena chotsekedwa ku chitoliro, koma ndi gawo lofunikira la chitoliro chokha.Kapangidwe kameneka kali ndi zabwino zingapo, kuphatikizapo:
1. Kupititsa patsogolo mphamvu: Flange yosakanikirana imapereka mgwirizano wamphamvu pakati pa chitoliro ndi flange, popeza palibe malo ofooka kapena njira zomwe zingatheke.
2. Kuchepetsa nthawi yoyika: The integrally cast flange imathetsa kufunika kwa zigawo zosiyana za flange, zomwe zingapulumutse nthawi panthawi yoika.
3. Kuchepetsa mtengo wokonza: The integrally cast flange amachepetsa chiopsezo cha kutayikira ndi zina zokonza, zomwe zingapulumutse ndalama pa moyo wa chitoliro.
Mapaipi achitsulo okhala ndi ma flanges ophatikizika amapezeka mumitundu yosiyanasiyana komanso kupanikizika, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito mosiyanasiyana.Zimagwirizananso ndi machitidwe osiyanasiyana ophatikizana, kuphatikizapo kukankhira, makina, ndi ma flanged joints.
Mapaipi achitsulo (DI) okhala ndi flanges mkati ndi mtundu wa chitoliro chomwe chimagwiritsidwa ntchito kwambiri popereka madzi ndi zimbudzi.Mapaipiwa amapangidwa kuchokera ku chitsulo cha ductile, chomwe ndi mtundu wa chitsulo chomwe chapangidwa ndi magnesiamu pang'ono kuti chikhale chofewa komanso cholimba kuposa chitsulo chachikhalidwe.
Ma flanges amkati ndi chinthu chofunikira kwambiri cha mapaipi awa, chifukwa amalola kulumikizana mosavuta ndi mapaipi ndi zida zina.Ma flanges amaponyedwa mwachindunji mu chitoliro panthawi yopanga, zomwe zimatsimikizira kugwirizanitsa kolimba komanso kotetezeka komwe kumagwirizana ndi kutayikira ndi mitundu ina ya kuwonongeka.
Mapaipi a DI okhala ndi ma flanges opangidwa mkati amadziwikanso chifukwa champhamvu komanso kulimba kwawo, zomwe zimawapangitsa kukhala abwino kuti agwiritsidwe ntchito m'malo ovuta komanso kugwiritsa ntchito komwe mapaipi adzalemedwa ndi katundu wolemetsa kapena kupanikizika kwambiri.Zimalimbananso ndi dzimbiri ndi kuwonongeka kwa mitundu ina, zomwe zimathandiza kukulitsa moyo wawo ndikuchepetsa ndalama zolipirira pakapita nthawi.
Ponseponse, mapaipi a DI okhala ndi ma flanges oponyedwa mkati ndi njira yodalirika komanso yotsika mtengo yopangira madzi osiyanasiyana komanso zimbudzi.Amapereka maubwino angapo pamitundu ina ya mapaipi, kuphatikiza mphamvu zowonjezera, kulimba, komanso kukana kuwonongeka ndi dzimbiri.
