Fabric Expansion Joints – Non-Metallic Expansion Joints
At Centreline we offer the complete package of:
We carefully select the correct Fabric expansion joint for the right application based on temperature and pressure
We have a qualified team of fitters that offer full installation on site, including removing existing expansion joint.
We offer a full turnkey package of design, supply and installation on all our Fabric expansion Joints. Centreline’s Non-Metallic Expansion Joints (NMEJ) offers a number of advantages, especially in plant design and building. They take up movements in several directions simultaneously, have almost no reactive forces, need little space for installation, are easy to adapt to existing physical conditions, and they are easy to transport and install.
Centreline’s NMEJ are designed on the basis of:
- Thermal Movements in the duct system
- Design values of the medium temperature and pressure
- Composition and nature of the medium flowing in the ductwork
- Gas velocity
- Dust content in the medium
- Special requirements with regard to installation
- Space availability etc.
Each of Centrelines NMEJ is custom built to suit the application in question with regard to:
- The temperature ranging from -65°C to +1400°C
- Choice of material and composition
- Fastening or tightening method
- Steel part and steel quality
- Insulation (bolster)
- Mechanical protection against abrasion (sleeve arrangement)
- Fabric expansion joint alone or pre-assembled on steel parts (units)
These NMEJs can be manufactured (against order) in all the necessary shapes and forms according to customer requirement viz. round, rectangular, square, oval, conical or combinations in different configurations shown below.
All fabric can be supplied as fabric part only or pre-assembled on steel parts for quick installation in the duct system.
Our range of expansion joints to suite all applications are as follows:
This variety includes a range of single layer expansion joints, materials, which cover a temperature range of -65°C to +200°C.
This series include a range of multi-layer expansion joints, covering most operating conditions in air or gas duct systems. The individual type of expansion joint is chosen on the basis of chemical composition of the medium, maximum operating temperature.
Bolster should be used to reduce temperature and avoid heat losses for system. Bolster will protect fabric expansion joint against abrasive media, accumulation of ash and thermal shock due to unburned fuel.
This series includes a range of products developed exclusively for the cement industry. The special feature of this series is its outer cover, which provides mechanical protection to the fabric expansion joint.
