Stainless steel flanges can be divided into

Small welding stainless steel flanges, medium stainless steel welding flanges, large stainless steel flanges, according to the connection type can be divided into: plate flat welding stainless steel flange, neck flat welding stainless steel flange, butt welding stainless steel flange, socket welding flange , Threaded flanges, etc., here is an introduction to the manufacturing process and use of large stainless steel flanges.

Features of stainless steel marine flanges

　First, it can be divided into pushing, pressing, forging, casting, etc. according to the production method.

　　Second, it is divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, ppc, etc. by material.

　　 Third, according to the manufacturing standards of marine flanges, it can be divided into national standards, electrical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.

　　 Fourth, the Japanese standard flange specifications are 10 kg Japanese standard flanges and 16 kg Japanese standard flange specifications.

Stainless steel flange container barrel size

Since the nominal diameter of the container barrel and the specific size represented by the nominal diameter of the pipe are different, the dimensions of the container flange and pipe flange of the same nominal diameter are also different, and the two cannot be substituted for each other. In addition to flat welding and butt welding flanges, the types of pipe flanges include cast steel flanges, cast iron flanges, loop flanges, threaded flanges, etc. The method and steps for checking and selecting pipe flange standards are the same as those for pressure vessel flanges. In addition to GB9119.7-88 for pipe flange standards, common standards include: Ministry of Chemical Industry standard HG20592～HG20602-97; Sinopec standard SH3406-96, etc. Among them, the standards of the Ministry of Chemical Industry are divided into the European system and the American system. The European system is commonly used in my country.
