Nthawi zambiri amakhala ndi utali wa pafupifupi 6 mita.Poyitanitsa chitoliro, wogwiritsa ntchitoyo ayenera kuyeza ma diameter akunja ndi mkati mwa chitoliro.Ngati makulidwe a khoma ndi ofunikira, chitoliro chikhoza kulamulidwa ndi OD ndi makulidwe a khoma kapena ID ndi makulidwe a khoma.
Pamaziko a zitsulo zapamwamba za carbon structural, chitoliro chachitsulo cha hydraulic chimawonjezedwa moyenerera ndi chinthu chimodzi kapena zingapo zowonjezera kuti zitsulo zikhale zolimba, zolimba komanso zolimba.
Mtundu wa chitoliro chachitsulo cha hydraulic chomwe nthawi zambiri chimapangidwa pozimitsira uyenera kuthandizidwa ndi mankhwala otenthetsera komanso kutentha kwapamwamba.Poyerekeza ndi chitsulo chapamwamba kwambiri cha carbon structural steel, zitsulo zomangira zimakhala ndi makina abwino, ndipo nthawi zambiri zimakulungidwa kukhala zitsulo zozungulira, zazikulu, ndi zowonongeka, zomwe ndi gawo lofunika kwambiri la makina kapena makina.Koma kukana kuvala ndi kudulidwa kukana ndibwino kwambiri kuposa chitsulo chosapanga dzimbiri.
Pali mitundu iwiri yamakalasi azinthu, ST52.4 ndi ST37.4.ST52.2 ndi chubu champhamvu champhamvu kwambiri, kutanthauza kuti ili ndi kukakamiza kwakukulu kovomerezeka pochepetsa makulidwe a khoma la chubu ndikuchepetsa kulemera kwadongosolo lonse.
