Rubber Expansion Joints
Aphrodite Polyprene Pvt. Ltd. is a leading manufacturer and supplier of the the most sophisticated range of Rubber Non Metallic Expansion Joints which find essential usage in Piping and Ducting Systems for Motion Compensation, Stress Relief as well as Noise and Vibration Control. These extension joints are widely used in different kinds of heating, ventilation and air conditioning systems to reduce vibration and stress in duct work which are caused by changes in the temperature or mechanical force exerted inside.
Our range of expansion joints are installed to isolate equipment such as pumps, compressors, chillers from the piping system. These joints help in adjusting the misalignment, reduce vibration of equipment flanges, adjusting for seismic movement preventing the transmission of noise and vibration. These Rubber Joints can be availed in different shapes, services and connection requirements.
Application of Rubber Expansion Joints
Rubber Expansion Joints finds wide application in different areas mentioned as follows :
Process Piping
The most vital use of our Expansion Joints is the protection of the Process Piping System. Some of the key features of this method are:
- Elastometric Expansion Joints help in reducing the noise and vibration which is caused due to forces in the pump or centrifuges as a shock absorber
- Handle different kinds of corrosive chemicals, abrasive slurries and reactive liquids or gases
- Excellent chemical resistance
- Besides, there are Teflon joints which are completely inert to all kinds of industrial chemicals and solvents
Power Plant Application
Our Rubber Expansion Joints find wide application nuclear and fossil fuel plants for compensating for thermal expansion and contraction on condenser lines, steam turbines, condensate lines, exhaust lines, cooling water lines and aeration systems. Some of the salient features of these expansion joints in the power plant application are:
- Reliability
- Long life
- Large size capability
- Easy accommodation for any application
Industrial Ducting Systems
Our comprehensive range of Rubber Expansion Joints have been successfully installed in the Industrial Ducting Systems. The key features of these joints in the ducting systems are:
- Used where flutter, heavy vibration, wet or dry corrosive materials are encountered
- These expansion joints are ideally used as retrofitting and also in the new construction
- The range can be customized as per customers designs and specifications
Marine Systems
The range of Rubber Expansion Joints are successfully used in the Marine Piping System by adding necessary motion and flexibility. Some of the key features of these Rubber Expansion Joints in this sector are as follows:
- Insulating against transmission of sounds with elimination of destructiveness of electrolysis
- The joints come with a compact look
- Carries high resilience
- Causes low stress
- Completely resistant to corrosive effects of hot saline water, brine and brackish water
- Common usage are: over board discharge line between condenser and hull, auxiliary hull, air intake on diesel engine, flush and sanitary systems, ventilation lines, fire and bilge pumps etc.
Pollution & Wastewater Systems
We are offering a flawless range of Rubber Expansion Joints which find wide and effective application in the Pollution & Wastewater Systems. These expansion joints are positively acclaimed for their different features like:
- Used in sewage treatment plants, water treatment plants and air scrubber systems
- Besides, these joints are also used in sludge pumps, secondary and raw sewage lines, centrifugal air blowers, scrub stacks etc
- Resistant to abrasion and corrosion
- Highly flexible in their usage.
Control Units Rubber Expansion of Joints
Rubber Expansion Joints are unrestrained in nature and they generally extend when they are pressurized. Premium quality of Control Units are used which are essential to anchor and support these joints for effective performance. Generally, two control units are mandate in normal condition where as more of them may be required to tolerate a thrust load at full system pressure.
There has been an utilization of the gusset plates which are bolted behind the matching flanges and control rods are inserted between them to restrict the extension of the joint. The number of rods required is dependent on the joint size and the operating pressure of the whole system.
Types of Rubber Expansion of Joints
Our range of Rubber Expansion Joints are available in different types which cater effectively to the different industrial purposes. These Rubber Expansion Joints are fabricated using top grade materials like Butyl, Neoprene, EPDM, Natural Rubber Compounds, Nitrile etc. The different types of Rubber Expansion Joints are:
Circular / Spherical Rubber Expansion Joints
These are available in size range from 40mm NB to 3000 mm NB
Rectangular Rubber Expansion Joints
These specific joints can be availed in size range from 40 mm x 40 mm to 2400 mm x 2400mm
Conical or Reducer Rubber Expansion Joints
These Conical or Reducer type Rubber Expansion Joints are:
- Available in size ranging from 40 mm NB to 2000 mm NB
- Offered in both concentric and eccentric designs which are essential to connect unequal size pipes.
- Made using high strength fabrics and elastomer which are equipped with flanges integrated with the body and use metal backing rings
- Materials used for fabricating these expansion are butyl or other elastomer tube and cover, also multiple plies of polyester or nylon cord along with reinforced steel wiring.
- Concentric Reducers are mainly used for the pipe having range of diameters between 2" to 24". There are arched rubber expansion joint having full face flanges and two-piece galvanized rings which are drilled to ANSI standards.
- Eccentric Reducers find wide application for pipe of diameter range of 2" to 80". We are offering arched rubber expansion joint that come with full face rubber and an offset centerline between flanges.
