Rubber elbow performance characteristics: 1, small size, light weight, good elasticity, easy installation and maintenance. 2, the installation can produce lateral, axial, angular displacement, from the pipe is not caring, flange is not parallel to the restrictions. 3, the work can reduce the structure to transmit noise, vibration absorption ability. The use of rubber elbow: As flexible rubber elbow with good overall performance, so it is widely used in chemical, construction, water supply, drainage, petroleum, light industry, refrigeration, sanitation, plumbing, fire protection, electricity and other basic engineering .
