1. Since most pipe fittings are used for welding, in order to improve the welding quality, the end parts are beveled, with a certain Angle and a certain edge. This requirement is also strict. The surface quality and mechanical properties are basically the same as pipes. For the convenience of welding, the pipe fittings are of the same steel grade as the pipe to be connected.
2. All pipe fittings should be surface treated. The iron oxide on the inner and outer surfaces should be sprayed off by shot peening, and then coated with anticorrosive paint. This is for export needs, moreover, in order to facilitate transportation to prevent corrosion and oxidation, we must do this work.
3, is the packaging requirements for small pipe, such as export, you need to do wooden cases, about 1 cubic meter, the number of elbows in the box can not exceed about a ton, the standard allows the set, that is, a large set of small, but the total weight generally can not exceed 1 ton. For large pieces y needs to be packed individually, like 24 "must be packed individually. Another is the packaging mark, the mark is to indicate the size, steel number, batch number, manufacturer's trademark, etc.

Hot push elbow forming process is the use of special elbow push machine, core die and heating device, so that the billet set on the mold in the push of the machine to move forward, in the movement of heating, expanding and bending forming process. Hot push bend deformation characteristics are based on volume before and after plastic deformation rule of metal materials determine the pipe diameter, pipe diameter bend diameter, through the core module and control the deformation of the process, make the inner arc compressed metal flow, the compensation to other parts of the thinned by hole diameter, wall thickness uniform Angle is obtained.
Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, suitable for mass production, so it has become the main forming method of carbon steel, alloy steel elbow, and 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 (heating ring can be multiple or single ring), flame heating and reflector heating, which heating method depends on the requirements of forming products and energy conditions.
