Mitundu iwiri ya mipope yamakina yopanda msoko

Chitoliro chachitsulo chosasunthika ndi chimodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri pamapaipi opanda zitsulo.Chitoliro chachitsulo chosasunthika chili ndi gawo lopanda kanthu ndipo palibe ma welds kuyambira pachiyambi mpaka kumapeto.Poyerekeza ndi chitsulo cholimba monga chitsulo chozungulira, chitoliro chachitsulo chosasunthika chimakhala ndi kulemera kopepuka pamene kupindika ndi mphamvu ya torsion ndi yofanana, ndipo ndi mtundu wachitsulo chamtengo wapatali.

Pali kwenikweni mitundu iwiri ya seamless makina zitsulo chitoliro:

Cold drawn seamless (CDS) ndi hot rolled seamless (HFS).Mapaipi onse achitsulo a CDS ndi HFS ali ndi mphamvu komanso kulimba, koma ubwino wopangira mtundu uliwonse wa chitoliro ndi wosiyana pang'ono.Kusankha ngati chitoliro chozizira chokoka chopanda msokonezo kapena chitoliro chotenthetsera chosasunthika ndichofunika kwambiri zimatengera momwe mungagwiritsire ntchito chitolirocho pakufunsira kwanu.

Chubu chozizira chokokedwa chopanda msoko chimapangidwa ndi chitsulo chotentha cha SAE 1018 cha carbon ndipo chimatambasulidwa kutentha.Panthawi yotambasula, nsonga ya chubu imadutsa mu nkhungu.Mphamvu imagwiritsidwa ntchito kutambasula chitsulo ku makulidwe ofunikira ndi mawonekedwe ndikusalala pamwamba.Chitoliro chachitsulo chamtunduwu chimakumana ndi muyezo wa ASTM A519.Amapereka mphamvu zokolola zambiri, kulolerana kwapafupi ndi malo osalala, kupanga chisankho choyamba cha ntchito zambiri zamakina.
