Expansion Joints
Rubber Expansion
Rubber Expansion Joints are engineered to provide efficient axial, lateral and angular movement absorption and in turn, significantly prolong the service life of the pipework and connected equipment. We offer a comprehensive range of rubber expansion joints and rubber bellows that provide cost-effective solutions for various demanding industrial applications. Our rubber expansion joints are designed to alleviate piping stress, absorb misalignment, handle movement, dampen noise, and reduce vibration over a relatively short face-to-face measurement. We offer a vast range of end connections such as threaded or flanged, with readily available plated steel and SS316 material options. We ofer flanged drillings in Table E/D, ANSI 150, ANSI 300, and DIN 16 configurations. Rubber options are EPDM, Neoprene, Nitrile (BUNA N), Butyl, Hypalon, Viton, and PTFE-lined options.
Sizes Options: 1" to 20". Temperature Ranges: Up to 120cDesign Pressure: 16 Bar
Metalic Expansion Joint
Fixed flanged expansion joints are equipped with welded carbon steel or stainless steel flanges. NFS's range of metal expansion joints are designed to withstand a wide range of applications, temperatures, and pressures, providing the capacity to absorb thermal growth in piping systems . Each expansion joint movements with the possibility of some lateral movements. Each expansion is custom made to suit each individual customers requirement or application so we can tailor a solution to the most difficult application.
Also available in floating flange option. We offer metallic expansion joints in both Stainless and Carbon steel.
Sizes Options: 1" to 12".
Temperature Ranges: Up to 500c
Design Pressure: 3 Bar
PTFE Lined Expansion Joint
PTFE lined expansion bellows combine the high-pressure rating of a metallic expansion joint with the high temperature and near-universal corrosion resistance of PTFE. PTFE or Teflon lined Expansion Joints are widely used in paper mills, chemical plants and other piping applications where acids and highly corrosive chemicals are being handled.
Sizes Options: 1.1/4" to 6".
Temperature Ranges: Up to 204c
Design Pressure: 8Bar
Rectangular Metal Expansion Joint
Rectangular metal expansion joints are flexible devices specifically designed to absorb the movement resulting from thermal expansion and contraction in duct systems. The bellows are typically constructed using durable metals like stainless steel, which provide the necessary strength and reliability in demanding operating conditions. Frames and bellows are available in a wide range of materials, sizes and configurations to suit individual customer requirements. These Expansion Joints are invariably used as customised solutions to expansion problems in rectangular ducting; they are purpose-designed and manufactured to match the customer’s individual application. Applications include Chemical process plants, Cement manufacturing, Pulp and paper industry ,Sugar plants & countless others.
