Cast iron expansion

    ※Craftsmen cast high-quality products, Innovation Cast iron expansion Product information points:Cast iron expansion is the main product of our company, the use of cast iron QT410 flange type expansion generally has a good absorption of axial and radial displacement function, for the bending of the pipeline has a good adaptability, mainly cast iron material is relatively soft, suitable for large Angle compensation in the pipeline has a good effect. It has a good compensation effect for the axial displacement caused by the settlement of the pipeline. Compared with the steel pipeline expander and rubber joint, it has the high-quality characteristics of high temperature resistance and greater wear resistance. It is generally used in chemical pipelines and powder transportation pipelines.
