EXPANSION JOINTS FOR BIOMASS BOILER DUCTS
IN A POWER PLANT

Belman Flexibles India engineered and manufactured 24 Expansion Joints – both metallic and fabric for biomass boiler ducts in a power plant in Europe.

CLIENT ISSUE
The engineering team of the client had made very good specifications and drawings for the project and were very specific in what Expansion Joints they needed. For them, it was important that we could design and manufacture according to their requirements as well as meeting the given delivery time.

BELMAN FLEXIBLES INDIA SOLUTION – Fabric & Metallic Expansion Joints for biomass boiler ducts
According to the client specifications and drawings we designed and manufactured 23 circular Metallic Expansion Joints sized DN 200-5400 and 1 fabric Expansion Joint (shown in the photo). As the Expansion Joints will be installed on different locations in the ducts around the boiler, they are made from different materials as well as having different shapes and different sizes.

Fabric Power Boiler Expansion Joint
The fabric Expansion Joint supplied is a type Belman-FG with steel flanges for bolting into the piping system. As the medium is flue gas. The Belman-FG Expansion Joint is a multilayer Fabric Expansion Joint ideally suited for accommodating the working conditions often found in flue gas systems, The sealing layer in the Belman-FG Expansion Joint is made from PTFE, which has excellent resistance to the chemical harsh environment found in flue gas systems.
The Fabric Expansion Joint is often used in flue gas systems, where the pressure is relatively low. In flue gas duct systems it is often required that the Expansion Joint transfers as little reaction forces to the pipeline as possible and here the Fabric Expansion Joint is the preferred product as it in practically sense does not have any spring rate. The Fabric Expansion Joints ability to take up large movements in multiple directions often makes it the preferred choice of Expansion Joint in flue gas systems.
