Cangzhou Bohai Pipe Co., Ltd. specializing in the production of 20 steel stamping elbow elbow elbow is a good, widely used and promoted 20 # carbon steel elbow quoted in different fields and industries, to varying degrees of application and popularization. Stamping elbow is the use of the same material of the plate and pipe stamping die stamping them into halves ring elbow, then bend the two half-rings were formed group of 20 # carbon steel welding elbow, pressing elbow welding need to follow certain The process for production and processing. Cangzhou Bohai Pipe Co., Ltd. specializing in the production of carbon steel elbow 20 elbow hot push forming process is the use of special elbow pushing machine, mandrel and the heating device, so set in the blank mold under the impetus pushing machine forward movement in the movement is heated, expanding and forming the bending process. Picks elbow tube diameter deformation characteristics are determined according to the law of constant volume before and after plastic deformation of the metal material, the use of the elbow tube diameter smaller than the diameter of the mandrel by controlled deformation of the blank, at the inner arc is compressed metal flow to other parts of the compensation due to the enlarged diameter and thinned, thereby obtaining a uniform wall thickness of the elbow. The main method of molding elbow hot push forming process has a beautiful appearance, uniform thickness and continuous operation, suitable for mass production features 20 # carbon steel elbow prices, and thus become carbon steel, alloy steel elbow, and is also used in Some specifications of the stainless steel elbows forming. Heating process of forming intermediate frequency or high frequency induction heating (heating coil may be a multi ring or lap), flame heating and reflection furnace heating, depending on what kind of heating the shaped product and energy requirements of decisions. 20 # carbon steel elbow manufacturers, Cangzhou Bohai (certified), Yantai Co., Ltd. 20 # carbon steel elbow pipe provided by the Cangzhou Bohai.
