Expansion joints are used for many different applications involving significant axial movement under pressure using external pressure expansion joints. They can absorb an almost unlimited amount of motion. What's going on here? The expansion joint is set up with fluid external to the expansion joint, which is subjected to atmospheric pressure internally to eliminate pressure instability In applications where an internally pressurized expansion joint would bend, an externally pressurized expansion joint can absorb the pressure. These joints allow greater axial flexibility with external unions placed under pressure and secured in a cap, such as a pipe or supply line. Learn more about the benefits of externally pressurized expansion joints by exploring related applications.
Advantages of Externally Pressurized Expansion Joints: Available in many different sizes and shapes, there are several benefits to using externally pressurized expansion joints in many applications. These benefits include: requires little maintenance, is customizable in size, compensates for thermal growth, is compact, and is very durable and long lasting. Many different industries utilize expansion bellows in their systems, including the oil, automotive and aerospace industries.
Typical applications for expansion joints under external pressure. Return and Supply Lines You will find return and supply lines in HVAC systems. Supply lines push hot and cold air from the air conditioning or furnace into the room, while return lines draw air into the ductwork heating and cooling system. This system is suitable for heat pumps, furnaces, radiant heating systems, boilers and baseboard heaters vertical risers include any system that passes vertically through the building. Examples include piping, ductwork and piping steam condensate pumps steam condensate helps drive water through boiler systems, water supply piping this system provides cold water and heat for homes and buildings the benefits of external pressure expansion joints span multiple industries and applications.
