EXPANSION JOINTS
SOLUTIONS
ENGINEERED FOR CRITICAL
EQUIPMENT
Metal and fabric expansion joints are engineered to absorb thermal movement, vibration and system misalignment while protecting piping and equipment from excessive stress. Designed for demanding industrial applications, they provide flexibility, reliability and extended equipment life across a wide range of temperatures and operating conditions.
Constituent of Flexible Material
The outer layer of the expansion joints is exposed to variety of gas and the structure must be flexible. It features high resistance chemicals and allows movement in all directions. The composition of material can be Fluoroelastomer and PTFE.
The thermal layer ensures that temperature on the inner part of the expansion joint does contain the required temperature.
For high temperature and acidity places the insulation pillow blankets are used. The bolster is secure by frames both sides, proper position is done by using welded pins with speed washers.

Associated Metal Work: Backup bars, frames, flanges and baffles
Metal Expansion joints prevent and solves problems such as: vibration, noise, shock, corrosion, abrasion, pipe system stress, thermal expansion and internal or external pressure working at high temperature.
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, size, design and different steel and materials are used to manufacture.
They are installed as flexible connections in air, flue gas pipe and duct system.
