The difference between the GB Flanged and ANSI Flanged Rubber Bellow
In the process of producing ANSI Flanged Rubber Bellows, Shanghai Songjiang Group relies on more than 30 years of production experience and professional technology, and at the same time innovates and introduces advanced vulcanization technology in the international rubber industry, and cooperates with the production process of domestic top Rubber Bellows to produce products with high service strength. and high-quality Shanghai Rubber Bellows with longer service life.
The Rubber Bellow has two connection methods: flange connection and screw thread connection. It is a pipeline joint with high elasticity, medium resistance and weather resistance. The industry has developed rapidly in recent years, and many manufacturers of American standard Rubber Bellows have emerged in the market, which undoubtedly makes the competition in the Rubber Bellow market more intense. What is the difference between the ANSI Flanged and the national standard flange?
The appearance and quality of national standard flange Rubber Bellows are guaranteed. The flange thickness, outer diameter, bolt hole diameter, and quantity are all national standard sizes, which are very different from many ordinary Rubber Bellows on the market. The national standard size of Rubber Bellows is mainly aimed at specifying the dimensional data of the ball and flange of the Rubber Bellow.
The ANSI Flanged is the part that connects the pipe to the pipe, and is connected to the pipe end. There are holes on the ANSI Flangeds, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. ANSI Flangeds can be cast or threaded or welded. The ANSI Flanged connection is a detachable connection. It is to fix two pipes, pipe fittings or devices on a flange first, add flange pads between the two flanges, and fasten them together with bolts to complete the connection. ANSI Flanged connection is an important connection method for pipeline construction.
The difference between the ANSI Flanged and the national standard flange is that the pressure is called differently: the American standard pressure is called pounds (class150LB refers to 150 pounds of pressure, which is equivalent to the PN2.0 pressure), followed by the different names of the specifications and calibers: The American standard calls the ANSI Flanged 2113 into two categories: ASMEB16.5 and ASMEB16.47. According to the 2009 edition of the Ministry of Chemical Industry standard, the 5261 national standard flange is divided into European standard system and American standard system, which are further revised and formulated with reference to the two systems of European and American flanges. Among them, the European series has nothing to do with the ASME ANSI Flanged.
