Expansion Joints fabric
Expansion Joints : TYPE C - Multi- layer Type : These are fabric expansion joint belts made from one or more reinforcement piles with coating of elastomers or fluro-plastics to form a homogenous material. They have inner layer made from ultra heat resistant silica or fiber glass or ceramic reinforced with SS 304 wire mesh, followed by silica mats/Glass mats or ceramic blankets lined with Teflon sealing layer. The outer layer consist of heat and weather resistant elastomer coated fabrics. These belts are usually bonded, sewn or mechanically fastened together using high temperature teflon coated silica threads with gasket arrangements on either side of the belt. These are designed for temperatures maximum 1260 degree celcius with Maximum Melting points upto 1649 degree celcius.
Insulation Bolster : These are cavity pillows made from ceramic or glass layers encapsulated in a fiber glass fabric and ss 304 wire mesh to prevent the accumulation of particulate matter or unburnt fuel trapped in the Expansion Joint cavity. This is designed for Expansion joint assembly along with the EJ belt. This is a complex belt design for heavy duty applications to handle corrosive flues at high temperature and
pressures upto 1649 degree celcius.
Salient features:
- Composite layered fabric belts recommended for Ultra high temperature flue gas applications.
- Designed for Highest flexibility and therefore the most allowance for movement.
- Belt systems are available for clamping at sites.
- Insulation bolster prevents the accumulation of corrosion particles in the EJ duct cavities protecting the fabric belts.
- Belts can be often installed out by the customers own personnel
- Cost effective and available ex-stock deliveries.
