90 degrees national standard elbow manufacturers of the production process

The forming process of making 90 ° GB elbow is a process of making special regular elbow by pushing machine, core die and heating device, which makes the billet on the mold move forward under the push of the pushing machine, and is heated, expanded and bent in the process of motion.The deformation characteristic of hot push elbow is that the diameter of tube billet is determined according to the law that the volume of metal material is unchanged before and after plastic deformation, and the diameter of tube billet is larger than that of elbow. The billet is controlled through the core mold, and the deformation process of the billet makes the inner arc of the compressed metal flow compensated to other parts that are thinned due to diameter expansion.Thus an elbow with uniform wall thickness is obtained.The forming process of national standard elbow by hot pushing has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, which is suitable for mass production. Therefore, it has become the main forming method of carbon steel and alloy steel elbow, and is also used in the forming of some specifications of stainless steel elbow.The heating method of forming process has medium frequency or high frequency induction heating ring, flame heating and reflection heating, which heating method is used to determine the main forming product requirements and energy situation.

The above is the production method of 90 degree national standard elbow, so that the production of 90 degree elbow is a common pipe fitting in our daily life.For example, water pipes, oil pipes and other gas and liquid carrying lumens are often connected at the corner by a 90 degree elbow.The 90 degree bend is a very important connection item, because of its convenience, wide use and low price by the customer favor.A good 90 degrees national standard elbow can ensure that the transportation of goods at the corner through the smooth leak, but also can bring a certain beauty.This is closely related to its production process.

The company mainly produces various types and angles of GB elbow, GB size head, GB pipe cap, GB tee, GB flange and other pipe fittings, welcome the need of customers to consult and order.The
