Molamu oa Sucker Bakeng sa Lifeme tsa China
C-class high quality carbon steel rod e entsoe ke SSYD-1 (e lekanang le AISI1526), e nang le matla a itekanetseng, polasetiki e ntle, mohato o khahlanong le kutu le lintlha tse ling bakeng sa tikoloho ea acidic medium ntle le ho baka khatello ea kelello ea sulfide.Grade D sucker e entsoe ka tšepe e phahameng ea Cr-Mo alloy 30CrMoA (e lekanang le AISI 4130), e nang le matla a phahameng, polasetiki e ntle, bophelo bo bolelele le litšobotsi tse ling, tse sebetsang tikolohong e sa senyang kapa e nyenyane ea liliba tse tebileng.Lithupa tsa li-sucker tsa Kreiti ea K li entsoe ka tšepe ea boleng bo holimo ea Ni-Mo alloy 20Ni2MoA (e lekanang le AISI 4620), e nang le matla a leka-lekaneng, ductility e ntle, ho hanyetsa kutu le litšobotsi tse ling, tse loketseng ho sebelisoa mejaro e bobebe le liliba tse sa tebang boteng. ea mecha ea litaba e senyang.
Ho latela moralo o tloaelehileng oa API, litšepe tsa sinki li entsoe ka tšepe ea boleng bo holimo ea lapeng kapa tšepe ea alloy.Lipheletso ka bobeli li na le likhoele tse tšoanang tsa kantle.Ho ea ka boemo bo tloaelehileng, e arotsoe ka 1 le 2, e ka kopanngoang le karolo e ka holimo ea molamu hantle, kapa qetellong ea molamu o monyang oa oli.
