The difference between flat welding and butt welding of flanges
First of all, we need to know what is a butt welding flange and a flat welding flange. The main differences between the two flanges are as follows: 1. Different forms of welds: The welds of flat welding cannot be detected by radiographs, but the welds of butt welding can be. The welding seam between […]
Classified according to the function and structural characteristics of the flange
Classified according to the function and structural characteristics of the flange Flange is an important pipe fitting, which can fix pipes and equipment, has a certain strength, and can resist mechanical vibration of pipe fittings. They are widely used in petroleum, petrochemical, metallurgy, thermal power, nuclear power and other fields, and can connect several pipe […]

Forged flange connections are widely used
Forged flange connections are widely used Process: In fact, it is precision model forging, sometimes called precision pressing or embossing. Putting the forging that has been model forged into a precision die groove and applying pressure to make it produce slight deformation, so as to obtain high-precision size and smooth surface forgings. The neck flange […]
Characteristics of stainless steel flanges
Characteristics of stainless steel flanges The stainless steel flange is characterized by fast welding speed and good weld shape. Stainless steel (stainless acid-resistant steel) flange is a disc-shaped part, which is more common in pipeline engineering, and flanges are used in pairs. In pipeline manufacturing, Flanges are mainly used for the link of pipelines. In […]
