Pipeline connections 85 bar

The 85 bar pipeline clamp coupling are used in boom concrete pumps, in concrete mixers with pumps and in simple and short stationary pumping systems. These are connections of the STK (SK) pipeline system with external sealing on the flanges. It is a standard and most commonly used system.

Its basic features are:

  • an easy way to connect pipes, elbows and other pipeline elements ,
  • pressure up to 85 bar,
  • a wide range of different types of snap couplings,
  • the ability to rotate the pipeline elements one against the other,
  • the possibility of slight misalignment of the axis of individual pipe elements by an angle of up to 2 degrees.

The multilateral character of pipeline STK connection system means that there is full interchangeability of connections between machines from different manufacturers. The variety of types of manufactured snap couplings means that thanks to this system, any pipeline connection can be provided – even those with very limited access and lack of space. .

Pipeline connections 85 bar are available in the following versions :
