High Performance Externally Pressurized + In-Line Pressure Balanced Expansion Joint for Oil Refinery in North Africa
We design and manufacture Expansion Joints for extreme challenging conditions.
When you combine high temperature, high pressure, aggressive medium, large movements to be absorbed, pressure thrust control, etc. the design and manufacturing become an engineering challenge.
On this occasion, our engineers have made a brilliant design and our factory has successfully completed the production of a very complex and special unit.
This unit combines all the factors that make it a very special and unique Expansion Joint.
MEP Series Externally Pressurized + In-Line Pressure Balanced
Designed such that fluid pressure acts on the outside of the bellows. This model is mainly used in cases of high pressure and large amounts of axial compression and extension.
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.
Main design and operating parameters and constructive features:
- High Pressure: tested at 48.4 barg (700 psi)
- High Temperature: +558 °C (1036 °F)
- Medium: Catalyst
- Multiply Bellows in SB443 N06625 (Inconel 625)
- Flange SA182 F347H
- Pipes SA312 304H
This unit has been ordered with Premium Service and it has been designed, manufactured and shipped to the client in only 5 days.
For more than 45 years MACOGA has produced standard and custom Expansion Joints specifically designed for extreme and critical applications.
