The applicable regulations and the requirements of the European Pressure Equipment Directive describe that special qualifications supported by a certificate are required for the assembly of flanged connections. Therefore, now Ośrodek Szkolenia Operatorów OSO invites all comers to course in the field of assembly of flanged connections.


What are flange connections?

Flange connections are the most common type of mechanical connection used in the construction of industrial installations. It is used mainly in the hydraulic industry in the creation of water supply and sewage systems. The assembly of mechanical connections is nothing more than joining two elements together with a connector, such as a screw. Each flange connection consists of several basic elements: two steel flanges, a gasket and connecting elements.

Flange connections have many advantages, which is why they are so eagerly used. They contribute to the tightness of the entire installation, which can serve us for many years to come. This exceptional tightness is achieved by using rubber gaskets or steel gaskets. This method provides rigidity to the structure, which increases protection against damage. The construction of the connection also allows for quick disassembly of the installation in the event of a breakdown or maintenance work.

We use flange connections with pipes:

  • cast iron with fittings
  • steel with fittings
  • PVC with fittings
  • HDPE with fittings
