 Chitoliro chopangidwa ndi polypropyleneimapereka maubwino angapo akagwiritsidwa ntchito limodzi ndi kuwotcherera kwachitsulo kwa A252 Giredi 2.Ubwino umodzi waukulu ndi kukana dzimbiri komwe kumabwera ndi polypropylene.Pogwiritsa ntchito chitoliro chachitsulo chokhala ndi polypropylene, malo amkati amatetezedwa kuzinthu zowonongeka, kuonetsetsa kuti moyo wautali ndi wodalirika wa mapaipi.Izi ndizofunikira makamaka pakugwiritsa ntchito komwe mapaipi amakumana ndi mankhwala owopsa kapena zachilengedwe.

Kuphatikiza apo, mapaipi okhala ndi polypropylene amadziwika ndi malo osalala amkati, omwe amathandizira kuchepetsa kukangana ndikuwonjezera kutuluka kwamadzi mkati mwa mapaipi.Izi zimawonjezera mphamvu komanso zimachepetsa kugwiritsa ntchito mphamvu, zomwe zimapangitsa kukhala njira yosangalatsa yamitundu yosiyanasiyana yamafakitale ndi malonda.

Ubwino winanso wogwiritsa ntchito chitoliro chokhala ndi polypropylene powotcherera ozungulira pansi pamadzi ndikuwonjezera chitetezo kuti zisavale.Mzere wa polypropylene umagwira ntchito ngati chotchinga, kuteteza mapaipi achitsulo kuti asawonongeke komanso kuchepetsa kufunika kokonza ndi kukonzanso pafupipafupi.

Kuphatikiza pa zabwino zomwe zimaperekedwa ndi polypropylene lining, njira yowotcherera ya arc yozungulira ndi chinthu chofunikira kwambiri popanga mapaipi okhazikika komanso odalirika pogwiritsa ntchitoA252 Gulu 2 chitoliro chachitsulo.Ukadaulo wowotcherera uwu umagwiritsa ntchito njira yowotcherera ya flux-cored arc yomwe imapanga ma welds amphamvu komanso osalala omwe amakwaniritsa miyezo yapamwamba yofunikira pamapaipi amakampani.
