90 Degree Rubber Expansion Joint for Plumbing System
90 degree rubber expansion joint is a flexible elbow connection, it can solve the connection problem that the pipes are not on the same horizontal plane. Meanwhile, it has good shock & noise reduction effect.90 degree elbow rubber expansion joint is composed of inner & outer rubber layer, reinforcement layer, reinforced metal ring and metal flange. It has the advantages of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, etc.
90 Degree Rubber Expansion Joint Features
1. According to the connection form, it can be divided into flange connection, threaded connection and threaded pipe flange connection.
2. According to the working pressure: 0.25MPa, 0.6MPa, 1.0MPa, 1.6Mpa, 2.5MPa.
3. Small size, light weight, good elasticity, easy installation and maintenance.
4. The installation can produce transverse, axial and angular displacement, which is not affected by the non concentric pipes and non parallel flanges.
5. When working, it can reduce the transmission noise of the structure and has strong vibration absorption capacity.
