Rubber Expansion Joints
The rubber expansion joints are designed for piping systems to absorb or contract to compensate and dampen the excessive force within the pipelines. They are extremely reliable and efficient even in operations in nuclear power plants which have extremely high pressure and temperature conditions. They are made of high quality rubber to improve efficiency in the engineered processes and have multiple applications in the various chemical and environmental industries.
PROPERTIES OF RUBBER EXPANSION JOINTS
The rubber has excellent properties which enables the extensive use of rubber expansion joints in various industries. Some of the properties of rubber expansion joints are:
• ABSORBS ALL DIRECTIONAL MOVEMENTS
The joints enable superior quality axial compression, axial extension and lateral deflection. Also, the joints provide angular and torsion direction along with many other advantages.
• REDUCES NOISE AND VIBRATIONS
The joints dampen and insulate the excessive noise and vibrations caused by the mechanical equipment.
• HIGH RESISTANCE TO SHOCKRELIEVES PIPE AND ANCHOR STRESS
They are ideally suited for earthquakes and other ground movement activities such as explosion.
• COMPENSATES FOR MISALLIGNMENT
They compensate for pipe misalignment until it can be corrected.
• PROVIDING ACCESS TO PIPING AND EQUIPMENT
The piping and equipment can be reached by just removing the joints which can be done with great ease.
• COST EFFECTIVE
They are much cheaper than the old traditional metal joints which required higher maintenance as well.
TYPES OF RUBBER EXPANSION JOINTS
The rubber expansion joints are primarily of two types:
MATERIALS (TYPES OF RUBBER) USED FOR PRODUCTION OF EXPANSION JOINTS
ESSENTIAL PROPERTIES OF VARIOUS RUBBERS ENABLING THE USE IN RUBBER EXPANSION JOINT MANUFACTURING
|NEOPRENE||Black||Excellent weather, oil and gasoline resistance.|
|EPDM||Red||Amazing ozone, sunlight, chemical, water and compressed air resistance. Great electrical insulation. Unsuitable for uses with oil, greases and gasoline.|
|NBR||Yellow||It has an excellent resistance against oil, gasoline, gases, solvent, greases, and abrasion.|
|HYPALON CSM||Green||Outstanding chemical and environmental resistance.|
|BUTYLL IIR||Blue||The rubber has amazing resistance towards chemicals, environment and compressed air.|
|VITON FPM||Purple||Highly suitable for oil, gasoline and solvents only.|
|PTFE||White||Remarkable resistance to all media except some chemicals at certain conditions.|
