Rubber Expansion Joints
Expansion joint is comprised of one or more metal bellows (most commonly stainless
steel) or from materials such as rubber, fabric or plastic such as PTFE.
While materials such as rubber, plastic and fabric have their limitations,
metal is the most versatile of all materials. Metals are suitable for use
at high temperatures, have high strength properties and are resistant to corrosion.
Expansion joints are considered as very important components of a complete pipe
system and are widely used particularly in industries where thermal expansion in
pipe systems occur. Expansion joints also offer the advantage of reducing stresses
in pipe systems generated by thermal expansion, and reduce pipe loads at connections
to sensitive equipment such as pumps and steam turbines. Taken together this acts to
prolong the service life of pipe systems, and reduces the risk of their downtime for
additional maintenance and repair.
In order to offer a complete product range for our customers, we also design and supply
rubber expansion joints. This ensures that our customers derive the
same benefits from our rubber expansion joints as from our steel expansion joints.
Expansion joints are important components in many industries and are used
extensively in among others:
- Energy sector (power plants, nuclear power plants, district heating pipe systems etc.)
- Steel plants
- Petrochemical industry (oil refineries, pumping stations, oil rigs etc.)
- Chemical industries (asphalt manufacturers etc.)
- Process industry (sugar factories etc.)
- Exhaust systems and engines
- Pulp and paper industries
- LNG/LPG tankers, -carriers etc.
Expansion joints are custom-made to suit any particular
application and are available as single- or multi-layer expansion joints.
