Expansion Joint is a product that maintains the piping system and protects equipment by absorbing high-stress magnitude on pipes due to outer temperatures that may influence energy delivering pipes, pipe expansion or contraction caused by temperature changes in fluids, equipment vibration problems, wind pressure or earthquake.
The basic element of a metallic expansion joint is the bellows – a flexible, corrugated tubular metal element to absorb movements in a piping & ducting solutions system. In the operating environment, the critical stresses and movements may act in axial, lateral or angular directions and the bellows must, therefore, be designed and dimensioned to accommodate these movements.
Expansion joints are used in piping systems to absorb thermal expansion or terminal movement where the use of expansion loops is undesirable or impractical. Expansion joints are available in many different shapes and materials.
Metallic Expansion Joints are installed in pipework and duct systems to prevent damage caused by thermal growth, vibration, pressure thrust, and other mechanical forces. There is a wide range of metallic bellows designed in a variety of materials. Options range from the simplest convoluted bellows used in petroleum refineries. Materials include all types of stainless steels and high-grade nickel alloy steels.
Rubber Expansion Joints are a flexible connector fabricated from natural or synthetic elastomers and fabrics with metallic reinforcements designed to provide stress relief in piping systems due to thermal changes. When flexibility for this movement cannot be designed into the piping system itself, an expansion joint is an ideal solution. Rubber expansion joints compensate for lateral, torsional and angular movements preventing damage and undue downtime of plant operations.
Non-Metallic Expansion Joints corrosion-proof, non-aging with extraordinary flex life and unmatched reliability. Non-Metallic 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 as pump connectors and a strategic point throughout a system.
They can be used to compensate for:
