This includes products ranges in materials such as fabric, rubber or Teflon / PTFE expansion joints.
When temperature is high, movement is significantly large and pressure less than 35 Kpag, a fabric expansion joint is specified. When temperature is below 200ºC, either a rubber or Teflon / PTFE joint is used.
Teflon expansion joints are used for temperatures below 316ºC and higher pressures, including full vacuum. Teflon expansion joints are most effective when the media is corrosive, such as sulphuric acid. For very high pressure we recommend PTFE lined stainless steel expansion joints.
Rubber expansion joints are selected to mitigate vibration impacts, in addition to absorbing thermal movement.
With applications below 200ºC. different rubber polymers are used depending on the media. There is no specific pressure limit due to the option to utilise reinforcement in our rectangular or circular expansion joints. We supply as either a standard joint, multi-convolutions, tied, hinged, gimbal, or in-line pressure balanced, up to 2200mm diameter.
Dog bone joints are used mainly in power generation applications, connecting the turbine to the condenser – these can be specified in different polymers and associated steel work.
Flexible rubber joints are low cost and can save the additional cost impact of operational downtime and repair costs of pumps and compressors. Our products are available in a broad spectrum of styles and sizes which eliminates the need for custom made joints.
Pulsating equipment such as pumps and compressors generate noise and vibration, which reduces efficiency in adjacent equipment and impairs working conditions for operators. Rubber expansion joints reduce such impacts, while preventing destructive vibrations that might otherwise cause ruptures and leaks.
Rubber expansion joints are manufactured to withstand corrosive chemicals. They are finish-coated with HYPALON to provide protection against acid fumes and ozone attack.
Flexible, lightweight rubber joints can be inserted in a minimum of space. For pipes up to 205mm, only 152mm face-to-face is needed.
They can withstand strong surge pressures without shattering due to their tensile strength. Our products allow four-axis movement and eliminate problems of pipes buckling or pulling apart.
Rubber joints are installed quickly and efficiently because they have extreme flexibility and light weight construction.
Rubber joints do not crack or fracture under repeated flexing. Our products have a remarkably long life expectancy, even under adverse conditions, because they are made only from the finest grades of rubber and other materials.
Unlike metal expansion joints, flexible rubber joints can stand up to the extreme of temperature and pressure. Our products, depending on styles, can stand up to pressure of 214PSIG and maximum temperature of 240ºF.
Because of its non-conductive characteristics, rubber makes the best expansion joint material for machinery where electrolysis can be a problem - rubber joints break electrolytic circuits.
Our products are available in an impressive range of types and sizes. They can accommodate pipes from 25mm to 610mm, with additional sizes available to custom order.
