Hi-Tech In-Line Pressure Balanced Expansion Joint for one the world's largest chemical producers located in the north of Europe

We have successfully completed the design, manufacturing and testing of Hi-Tech In-Line Pressure Balanced Expansion Joint for one the world's largest chemical producers located in the north of Europe.

A pressure balanced expansion joint accommodates axial and lateral movements and counteracts the bellows pressure thrust. An additional bellows is incorporated into the unit and is subject to the line pressure to generate a force equal and opposite to that on the main bellows. Tying these bellows together neutralises the pressure load on the unit.

Main mechanical design, parameters and features of the expansion joint supplied are:
