In building construction, for special applications such as steel structure, steel beam, steel column and steel plate, the special sleeve welded with it and connected with straight thread joint at the other end is called weldable sleeve, which is made of high-quality 20Cr alloy steel.
High quality 20Cr alloy steel has good comprehensive mechanical properties, good low temperature performance, good plasticity and weldability. It is used as structures, mechanical parts, building structures and general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations and bridges. It can be used in hot rolling or normalizing state. It can be used for various structures in cold areas below - 40 ℃.
C45 and 20Cr materials are generally used for weldable sleeves, but C45 materials have extremely strict requirements on welding process and welding environment, resulting in low welding qualification rate. Therefore, our company mainly produces 20Cr weldable sleeves. Please consult manager Zhu for specific information.
