Kodi amapeto a stubndi chifukwa chiyani iyenera kugwiritsidwa ntchito? Malekezero a stub ndi zida za buttweld zomwe zingagwiritsidwe ntchito (kuphatikiza ndi lap olowa flange) m'malo mwa kuwotcherera khosi ma flanges kuti apange ma flanged. Kugwiritsiridwa ntchito kwa malekezero a stub kuli ndi ubwino wake: kungathe kuchepetsa mtengo wonse wa ziwalo za flanged za machitidwe a mapaipi mumagulu apamwamba a zinthu (monga momwe chiwombankhanga cholumikizira sichiyenera kukhala chamtundu womwewo wa chitoliro ndi mapeto a stub koma akhoza kukhala otsika);imafulumizitsa njira yoyikapo, monga momwe flange ya lap imatha kuzunguliridwa kuti igwirizane ndi mabowo a bawuti.

- Mtundu wa B wa Stub uyenera kugwiritsidwa ntchito ndi ma flanges okhazikika
- Mapeto amtundu wa C atha kugwiritsidwa ntchito limodzi ndi ma lap joint kapena slip-on flanges ndipo amapangidwa kuchokera ku mapaipi.
