1, Product Performance: Ansi standard flexible pipe rubber joint is extremely suitable for places where there are complex geologic conditions, large sedimentation range and pipes are easy to be damaged due to frequent alternation between heat and coldness in pipes. The elastic slide transfer and deformation of rubber and the heat dispersion of mechanical force may well prevent the physical damages from the displacement of pumps, valves and pipes. As a poor conductor, it is a harmless to reduce the vibration and noise transmission. The product is designed with smooth inner walls, after testing, it is proved to have no any influence on the flow speed and flux of medium, and keeps stainless for ever, accordingly it will be free of maintenance in operation. 2, Product Application: For air conditioning, heating and ventilating systems in industrial buildings and vessels. Central and ancillary power generating stations in industrial buildings, factories, ships and off-shore applications Sewage disposal and water treatmentplant, pumps, etc. Process piping in pulp and paper plants Piping systems for chilled or hot water in industrial plants Cooling systems for power generation Feed water and draining lines for water works, sewage, sanitary piping systems etc. Oil lines for industrial plants, shipyards, phosphate plants etc. Potable water applications Food applications 3, Product Selection: A limiter must be added when actual work pressure of the rubber compensator reaches 70% or the rubber compensator is installed at the bend or the tee junction. It is recommended to select a transmission type rubber compensator which is installed at the exit of pipe or pipelines adjacent to the exit. It is recommended to select a flush type rubber compensator which is installed on long pipes or structures.
