DN 1500 MPB-I In-Line Pressure Balanced Expansion Joint for a manufacturer of forest products

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. The only loads on the equipment are the sum of the forces required to move the line bellows and balancing bellows of the expansion joint. This type of Joint can be fitted between intermediate fixed points so main anchoring of the pipe or adjacent equipment is not required. MACOGA has delivered one DN 1500 (60 inch) MPB-I In-Line Pressure Balanced Expansion Joint for a Cogeneration Biomass project in Europe for a manufacturer of forest products: lumber, pulp, paper and specialty cellulose with operations in North America and France.
