Butt welding flange is a different production standard. Because the nominal diameter of the vessel barrel and the nominal diameter of the pipe represent different specific sizes, the sizes of the vessel flange and pipe flange with the same nominal diameter are not the same, so they can not be substituted for each other.
Carbon Steel Flanges Butt welding flange technical data sheet as below:

Butt welding flange is a common standard gb9119.7-88, and the standards used include: Ministry of chemical industry standard hg20592 ~ hg20602-97; Sinopec standard sh3406-96, etc. The standards of Ministry of chemical industry are divided into European system, American system, etc., and European system is commonly used in China. Due to low operating pressure and small diameter, type a flat welding flange and plane sealing surface can be used, and asbestos rubber plate is used as gasket material.
Butt welding flange is the connection bolt, the material is Q235-A, 2 ", 4" flange is selected. The pressure grade, material and standard of flange have different characteristics and characteristics, which can be produced and processed according to the corresponding standards in accordance with certain principles and methods in use, so as to ensure good use value and function in use.
