Expansion Joints

Product/Service Name

Metallic Expansion Joints, Rubber Expansion Joint and Teflon Expansion Joints

Function / Application  
Any pipe connecting two points is subjected to numerous types of action which result in stresses on the pipe.
Some of the causes of these stresses are: 

• Internal or external pressure at working temperature
• weight of the pipe itself and the parts supported on it
• movement imposed on pipe sections by external restraints
• thermal expansion

These engineered designed Expansion joints are manufactured specifically to resolve such problems.   

Metallic Expansion Joint
Metallic Expansion Joints (Bellows) are installed in pipe work and duct systems to prevent damage caused by thermal growth, vibration, pressure thrust and other mechanical forces. Materials include all types of stainless steels and high grade nickel alloy steels.  

Rubber Expansion Joint Rubber Expansion Joints are flexible connectors fabricated of natural or synthetic elastomers and fabrics and metallic reinforcements, which are designed to provide stress relief in piping systems due to thermal changes.

The special construction of the rubber joints can solve problems like vibration, noise, shock, corrosion, abrasion, stresses, load stress, equipment movement, vibration, pressure pulsation and movement in a piping system. When flexibility for this movement cannot be designed into the piping system itself, an expansion joint is the ideal solution.

Rubber expansion joints compensate for lateral, torsional and angular movements preventing damage and undue downtime of plant operations.  

Teflon Expansion Joint
Teflon Expansion Joints are corrosion proof, non-ageing with extraordinary flex life and unmatched reliability. The Teflon expansion joint has widespread acceptance in the chemical processing industry, piping applications where acids and highly corrosive chemicals are being handled and commercial heating and air conditioning systems.

They can be used to compensate for movement, misalignment, axial travel, angular deflection, and or vibration in piping systems.
