METAL EXPANSION JOINTS
Since 1994, Belman has been manufacturing Expansion Bellows of all types and shapes in various materials such as stainless steel, rubber and fabric for a long list of critical applications.
Our experience and broad product range enable us to provide high quality solutions and services for the benefit of our customers, ensuring a long service life for both the Expansion Bellows and the piping systems they protect. All Expansion Joints (also known as Bellows) are engineered specifically to suit the customers project and to solve the expansion problem. This is what we do.
To meet the expectations of high safety, engineering must be supported by reliable and verified calculations. We calculate therefore according to the latest design codes, recognised by international classification associations. The required solutions can be supplied with CE-marking in compliance with the Pressure Equipment Directive (2014/68/EC).
