It is possible to manufacture the sealing surface of a butt welding flange in three different shapes: smooth, concave, and convex (see illustration). In addition, the tenon groove type is available. Flowing water and compressed air at low pressure without filtering are both examples of medium conditions that are frequently encountered in the workplace. Its most significant advantage is that the pricing is extremely competitive.

For butt welding flange, pipelines with significant variations in pressure or temperature are appropriate candidates, as are pipelines with high temperatures, high pressures, and low temperatures. It is also used in the construction of pipelines that transport highly expensive, volatile, and explosive media such as natural gas and petroleum. Butt welding is used in conjunction with the pipeline to make the connection between the flange of the butt welding flange and the pipeline. Large pipe diameters are typically covered with double-sided welding to ensure strength and durability.

Its most significant advantage is that the pricing is extremely competitive.

Generally speaking, butt welding flanges are treated by dividing them into a large number of arc segments, which are then welded together:

The process begins with the formation of a square blank, which is then cold bent into an arc segment, which is then heat treated and stress relieved before being joined together to form a complete circle and being processed on a vertical lathe to the desired shape and size.

It will then be transported to the construction site, where it will be assembled and welded to the pressure vessel using various arc segments to form a full special-shaped butt welding flange.

3. There are numerous production criteria for butt welding flanges, which vary depending on their use and manufacture. It is possible to ensure that the value and function of special-shaped stainless steel flanges are realized in practice if they are manufactured and used in accordance with appropriate specifications and standards.

In a variety of industries, including aerospace, petroleum, chemical, and others, butt welding flangeare widely used as a sealing and fastening connector in large vessels, particularly in the aerospace industry.
