Metal bellows (DN25 - DN8000MM), stainless steel corrugated hose (DN6 - DN800MM), fabric thermal compensation, PTFE hose, PTFE compensators are widely used in petroleum, chemical, mining metallurgy, instrumentation, aerospace, shipbuilding, construction, power plants, thermal power, electronics, heating pipes, machinery manufacturing and other industries duct smoke, hot air pipes, dust imports, imports of other parts of the fan to compensate for high-rise buildings are not synchronized with the device subsidence; compensation due to the large tanks and pipe supports crust displacement caused; distortion compensation projects in the pipeline system expansion and contraction caused by my factory has worked to provide various types of high quality compensator for large enterprises and power plants. Within the current pressure bellows manufacturers, the company has the CAD design center pressure bellows weight, pressure inside the test center bellows, and in strict accordance with GB/T12777-99 and GB/T14526-93 national standards, and the adoption of international standards bellows design and production, also called the customary pressure bellows expansion joint performance, or expansion joints. Constituting the work by the bellows body (an elastic member) and the end pipe, brackets, flanges, pipe and other accessories. Mainly used in a variety of pipe, it is possible to compensate the thermal distortion of the pipe, the mechanical deformation and absorb mechanical vibrations, serves to reduce stress and improve the deformation of the pipe conduit life effect. Bellows and welded connections are divided into two flange connection. Buried pipes commonly used welding compensation [the] Sanming bellows pressure, internal pressure bellows manufacturers million harbor harbor provided by the million.
