Pipe expansion joints provide the flexibility that systems need to be functional. On HVAC systems, they allow the pipes to accommodate the changes in temperature and pressure that are predictable in these systems. Whether they're containing the water coming out of a boiler or the heated air coming out of a furnace, these systems have to be durable and have to give predictable results under pressure.

The Bellows System

Most pipe expansion joints make use of a bellows. The convolutions on a bellows allow the pipe expansion joints to absorb the pressure increases in the line, the expansion from heating and cooling and the vibration that presents hazards to any system. These expansion joints consist of different parts that are used to handle different types of force. While the bellows does a great job on its own, there is an entire system involved in pipe expansion joints that has to be installed and configured correctly.

The Forces on Pipe Systems

Pipes endure many different types of forces. Axial forces run along the established path of the pipe expansion joints. Lateral forces exert pressure on up and down on the pipe and angular forces expand one side and contract the other side of the bellows. Pipe expansion joints have to be able to handle all of these so that the integrity of the system is maintained. To that end, they are fitted with other devices that augment their function. Hinges, pipe anchors, tie rods and gimbals are all used for this purpose. Correctly engineered and installed, pipe expansion joints can endure tremendous pressures.

Finding the Flexonics Experts

Senior Flexonics Pathway can help businesses and industry find solutions for pipe expansion joints in challenging environments. By combining their engineering experience with their practical experience in the field, they can make sure that businesses have all the tools that they need to get the best out of their systems. Pipe expansion joints that are made of the appropriate materials and to exacting specifications can provide effective and reliable service for a long time.

Without the right pipe expansion joints, a system is not flexible and dynamic enough to deal with the everyday stresses that it endures. Any changes in pressure or additions of mechanical force may compromise the system. To make sure that the risks of this happening are significantly lessened, pipe expansion joints made of metal and cloth are available and provide the needed tolerance to force.
