The series of sleeve type expansion joints produced by our company are optimized and manufactured by integrating the strengths of various products and years of production experience. Under the same working conditions, they have a longer service life, lower production costs and processing difficulties. Especially for large-diameter products, the composite pipe technology is adopted (the core pipe is lined with a thin stainless steel plate, which makes it do not require fine turning, planing and electroplating. Not only is the surface of the core pipe smooth, but also the friction resistance It is small, and its anti-corrosion ability has also been greatly enhanced, thereby significantly extending the service life of the product.
Brief installation Instructions
The VSSJA-2 type double flange limit expansion joint is suitable for flanged connections on both sides.
2. All products have been assembled before leaving the factory. Just connect both sides of the product to the pipe flange, evenly tighten the nuts beside the cover diagonally, and then adjust the limit nuts properly.
3. During the pressure test, the pipes on both sides of the product should be fixed well to prevent the product from being damaged due to excessive axial load.
Purpose
This product can be widely used in the circulating water systems of hydropower plants and thermal power plants, as well as various valves, pumps and other systems.
2. It can be used as a compensator in the heating network.
3. Flanges can be configured according to the user's requirements (the flange standards listed in the table are GB/T9112-9124-2000)
4. Products with a pressure not exceeding 64Mpa can be designed and manufactured according to the user's requirements.
Our company has a total of eight different structural forms of expansion joints and can design and manufacture them according to the requirements of users.
