What are the features of stainless steel elbow?  

Have very lively chemical properties at high temperature, small thermal conductivity, heat capacity is big, in the stainless steel elbow welding, pipe weld easy to oxidation and air pollution problems, seriously affect the welding quality, therefore, the stainless steel elbow welding pipe must be used when the internal charge gas to solve the oxidation problem of the internal weld.  

At present, the domestic steel elbow forming manufacturing commonly used processing methods are: casting method, stamping pressing method, welding method, cold and hot push method.  The pressing method ---- in the elbow machine will be heated tube blank with mold bending processing method, this method was first used in the tube elbow bending processing process method, in the elbow production has been widely used.  However, this method produces uneven wall thickness of elbow, poor appearance quality, and high mold manufacturing cost when processing large elbow.  

Stainless steel elbow elbow is first used for pipe turning a pipe fittings, in all pipe fittings applied in the pipeline system, accounting for more than 80% of the proportion, is a very important pipe fittings, elbow push machine is the production of elbow mechanical equipment, through high temperature push system, or hydraulic cold push elbow mechanical equipment.  There are mainly cold push elbow machine, medium frequency induction heating elbow machine (the main power is hydraulic cylinder).  Customers can choose according to their own needs.
