Stainless steel elbow processing method
It is a general term for a variety of stainless steel pipe connection workpieces, which is beneficial to the device, strong performance, durable and other series, and is widely used in various pipe construction and devices.
Therefore, how should the stainless steel butt welding elbow be installed? Next, follow the small series to understand. Backwelding method is adopted for starting the arc of stainless steel butt welding elbow, and full arc pit method is adopted for closing the arc.
How to install stainless steel butt welding elbow
In the overweighing of arcing, it should be finished in the slope, and it can not be arcing and arcing on the surface of the pipe and pipe fitting bus. In the process of starting the arc, cracks, pores and other problems are found, and they should be dealt with in time.
When the stainless steel butt welding elbow is hoisted, it should be separated from other metals to avoid direct contact. It can be used to block non-metal materials such as high wooden boards and rubber sheets.
Stainless steel butt welding elbow in the continuous welding process, the temperature shall not exceed 60 degrees Celsius. When positioning welding, the inside of the weld should be filled with argon protection.
When cutting, you can not use the ordinary grinding wheel to cut, you should use the stainless steel butt welding elbow special grinding wheel or plasma cutting.
When the stainless steel butt welded elbow pipe and non-stainless steel pipe and pipe fittings are connected, the pipe and cavity of the welded butt joint should be filled with argon gas before the bottom welding, and then the tungsten argon arc welding can be carried out. The welds at the joint joints must be pickled and passivated after welding.
Stainless steel elbow processing method
The production and processing methods of stainless steel elbow pipe fittings are also good and diverse. Many still belong to the machining industry, the most used is stamping method, forging method, roller processing method, rolling method, bulging method, stretching method, bending method, and combined production and processing method. The production and processing of pipe fittings is a close combination of machining and metal pressure processing.
Forging method: The end or part of the pipe is thrust with the type forging machine, so that the outer diameter is reduced, the commonly used type forging machine has rotary type, connecting rod type, roller type.
Stamping method: In stainless steel elbow with taper core to expand the size and shape of the pipe end required. Roller method: The core is placed in the tube of the stainless steel stamping elbow, and the outer part is pushed by the roller to produce and process the round edge
