Externally Pressurized Expansion Joint
Externally Pressurized Expansion Joints: Ideal for High Expansion and Pressure Applications
ORFA Industrial Products Industry and Trade Inc. offers a wide range of products to meet the demanding requirements of industrial pipelines. Safely and effectively absorbing the high expansion pressures encountered in very long pipelines is crucial, especially. To address this need, ORFA Industrial sells high-performance externally pressurized expansion joints.
Importance and Working Principle of Externally Pressurized Expansion Joints:
In very long pipelines, expansion due to temperature changes can reach significant dimensions. Multi-corrugated expansion joints can be used to absorb this expansion. However, an increased number of corrugations also increases the risk of expansion joint buckling. While the use of liner can partially prevent this, the most reliable and effective solution is the use of externally pressurized expansion joints. Furthermore, externally pressurized expansion joints are an ideal option for systems transporting fluids requiring high safety requirements, such as hot oil.
In externally pressurized expansion joints, the fluid direction is changed to apply pressure outside the bellows. This special design results in expansion joints that can withstand high pressure and expansion without buckling.
Advantages of Externally Pressurized Expansion Joints:
The externally pressurized expansion joints sold by ORFA Endüstriyel offer many important advantages:
- High Expansion Absorption: Safely absorbs high expansion amounts in very long pipelines.
- Buckling Resistance: Thanks to its special design, it eliminates the risk of buckling under high pressure and expansion.
- High Safety: Provides safe use in systems where hazardous fluids such as hot oil are transported.
- Wide Range of Applications: Can be used to solve thermal stability and mechanical expansion problems in all types of pipelines. It has a wide range of applications, especially underground pipelines and geothermal lines.
- Different Expansion Values: Although manufactured with standard expansions of 30, 60, 90 and 120 mm, special production with different expansion values is also possible according to customer demands.
