Mwachindunji, mankhwala athu anawagawa tayi ndodo mtundu shockproof mafupa ndi ukonde chivundikiro mtundu zimfundo shockproof, ndi tayi ndodo mitundu anawagawa mu mtundu kuwotcherera ndi zofunika akamaumba mtundu.This-chidutswa mtundu akhoza kuonetsetsa ukhondo wa payipi, ndi flange ndi zopangidwa ndi chitsulo cha carbon. Kuyeretsa kwamtundu woterewu kumatha kuchepetsa mtengo.

Kukula mafupa amagawidwa mu axial kukulitsa mafupa ndi ofananira nawo kukula joints.Axial kuwonjezera mafupa makamaka ntchito kuyamwa kukula ndi psinjika mapaipi mu malangizo yopingasa. Malumikizidwe okulirapo amatchedwanso kuti Vientiane expansion joints. Amayamwa kusunthako kolowera kumanja kudzera m'mphepete mwa mavuvu kumbali zonse ziwiri. Makamaka kuonetsetsa kuti payipi ikugwira ntchito bwino, ili ndi ntchito zotsatirazi: kubweza ndi kuyamwa axial, ofananira nawo komanso ang'ono matenthedwe matenthedwe a payipi; kuyamwa kugwedezeka kwa zida ndikuchepetsa kugwedezeka kwa zida paipi; kuyamwa mapindikidwe a payipi chifukwa cha zivomezi ndi kuchepa kwa nthaka.
