Application:
Reducing flexible rubber joint is widely used in the field of chemical industry, construction, supply water, sewage drainage, petroleum, light and heavy industry, sanitation, plumbing, electricity and other fundamental engineering.
The inner seamless high-pressure rubber joint is developed by us which prevents corrosive medium from etching the inner wall of the rubber joint in high temperature, acid, alkali and oil resistance pipeline, thereby it also can extend its service life span.Structural noise transmission can be reduced with the restrict and flange non-parallelism.
Reducing flexible rubber joint is consist of fabric reinforced and metal flange loose joint.
It has the characteristics of compact structure,light weight,high flexibility,easy installation,long service life.
Expansion joints are specially engineered products inserted in a rigid piping system to achieve one or more of the following:
Absorb movement
Improved thermal stability
Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
Reduce mechanical noise
Compensate for misalignment
Eliminate electrolysis between dissimilar metals
The range of our engineering emphasis extends from the selection of the fabric used for reinforcement to the choice of materials used in actual expansion joint construction. Rigid laboratory and field tests of Macro expansion joints are what back up our assurances of long life and reliable service. An important word on safety: all Macro expansion joints carry safety ratings exceeding product specifications in such areas as pressure and movement. Macro nonmetallic expansion joints and flexible couplings are ideally suited for hundreds of applications in a wide range of industries, including:
Power Generation
Pulp and Paper
Chemical Processing
Water/Waste Water
Marine
Mining
Heating, Ventilating, and Air Conditioning
Expansion Joints offer superior performance, reliability, and service life. This in turn improves plant safety, increases the mechanical integrity of equipment, and allows customers to gain a competitive advantage in the marketplace.
