Elbow pressure balanced expansion joints (also known as corner relief expansion joints) are used on piping system where direction changes and the force exerted on piping and /or associated equipment from pressure thrust is intolerable. This arrangement uses dual connected bellows at line pressure acting in opposite directions.
Elbow pressure balanced expansion joints are designed to compensate for axial movement due to these external forces, thereby protecting the system.
Hyspan, a world leader in the manufacture of bellows expansion joints, packed slip expansion joints and ball joints for industrial applications. Hyspan produces a complete line of flexible tubular products that meet the needs of diverse industries ranging from scientific research to oil refining.
The image above of a 24” NPS Hyflex pressure balance universal elbow expansion joint that is almost 15 feet long used in a geothermal power plant illustrates their ability to engineer and manufacture custom products to meet any need.
