SEIRIS Fabric, Metal and Rubber Expansion Joints
Founded in 1978, SEIRIS specialises in developing, manufacturing, selling and installing expansion joints, as well as flexible connections for piping and ducting systems.
In the power industry, the company’s fabric metal and rubber expansion joints serve coal, gas, biomass, hydro and waste-to-energy power plants, as well as water desalination facilities.
In other industries, SEIRIS works at facilities in areas such as cement, steel, and chemical and petrochemical. The firm works in close collaboration with original equipment manufacturers (OEMs), as well as engineering, procurement and construction companies.
Complete solutions for industrial expansion joints
SEIRIS expansion joints are installed worldwide and the company has production facilities in Paris, France; Sousse, Tunisia; and Hyderabad, India.
The dimensions, shapes and operating conditions of clients’ most critical applications are customised to meet exact specifications and internationally recognised standards (ESA, FSA, EJMA, ASME, AD MERKBLATTER, ASTM, ABS).
SEIRIS offers complete solutions from design to installation of its expansion joints.
Fabric expansion joints (non-metallic)
Mainly used in ducts at low-pressure and for gaseous fluids, SEIRIS fabric expansion joints allow for four different movement types (axial, lateral, angular and torsion) and solve duct misalignment, vibration, and acoustic problems.
They can be designed:
- Circular or rectangular
- Single layer or multiple layers
- U-type or belt-type configuration
- With or without bolster (insulation)
- With or without steel frame
- Material: a range of technical textiles
- Temperature: up to 1,200°C
- Pressure: up to 0.25bar
Metal expansion joints for power applications
Primarily selected for their resistance to high-pressure, metal expansion joints are designed according to the type of movement they have to endure and meet international standards after being subject to a wide range of tests.
These expansion joints are also tailor made:
- Circular or rectangular
- Single ply or multiple plies
- Single convolution or multiple convolutions
- Welded or flanged-type configuration
- Material: carbon steels, austenitic stainless steels, nickel alloys
- Temperature: up to 1,200 °C
- Pressure: up to 120bar
Rubber expansion joints
Particularly useful for aggressive chemicals and for abrasion resistance, Rubber expansion joints are manufactured from various elastomers with fabric and wire reinforcing, vulcanised and provide appropriate movement capabilities.
Customised designs are our speciality. We offer:
- Circular or rectangular
- Single ply or multiple plies
- Single convolution or multiple convolutions
- Swivel or full face flanges type configuration
- Materials: wide range of rubber
- Temperature: up to 200°C
- Pressure: up to 25bar
