Mtengo wa chitoliro chachitsulo chosasunthika cha mamita 6 ndi wapamwamba kuposa wa chitoliro chachitsulo chosasunthika cha mamita 12 chifukwa chitoliro chachitsulo cha mamita 6 chili ndi mtengo wodulira chitoliro, m'mphepete mwa chitsogozo cha mutu wosalala, kukweza, kuzindikira zolakwika, ndi zina zotero. Ntchito yawonjezeka kawiri.

Mukagula mapaipi achitsulo opanda msoko, ganizirani kusiyana kwake. Mwachitsanzo, makulidwe a khoma la chitoliro chachitsulo chokhala ndi dayamita yakunja yaASTM A106 GrB159*6 ikhoza kukhala 159*6.2 yokhala ndi makulidwe a khoma a 6.2 mm. Ngati kusiyana sikuganiziridwa, malipirowo adzalipidwa mopitirira muyeso kulemera kwake kukatha. Komabe, njira yopangira yomwe ikugwiritsidwa ntchito pakadali pano singapange kusiyana kulikonse, zomwe ndi kusintha kwakukulu mumakampani opanga mapaipi achitsulo osasokonekera.

Mapaipi ambiri achitsulo osapindika sali okhazikika kutalika. Ena akhoza kukhala mamita 8-9, mamita 8.5, mamita 8.3, kapena mamita 8.4, koma mutha kudziwa kuchokera pazithunzi za katunduyo ngati wakhazikika kapena ayi. Mwachitsanzo, gulu lotsatira la katunduyo lakhazikika kutalika kwa mamita 12 ndipo lapangidwa bwino kwambiri.
