Seamless Alloy Steel Tube

Chitoliro cha aloyi ndi mtundu wa chitoliro chachitsulo chopanda msoko, ntchito yake ndi yokwera kwambiri kuposa chitoliro chachitsulo chosasunthika, chifukwa chitoliro chachitsulo chamtunduwu chimakhala ndi Cr yambiri, kukana kwake kutentha kwambiri, kutsika kwa kutentha, kukana kwa dzimbiri ndikwabwinoko kuposa  zina. Chitoliro chachitsulo , kotero chitoliro cha aloyi chimagwiritsidwa ntchito kwambiri mu petroleum, zakuthambo, mankhwala, mphamvu yamagetsi, boiler, asilikali ndi mafakitale ena.

Ntchito: Mu Petroleum, Azamlengalenga, Chemical, Power, Boilers, Military Industry

Mapeto: Plain End, Beveled End, Thread End
