What are bellows?

An Expansion Joint ( Bellows ) is used in the piping system to absorb thermal expansion or terminal movement, where the use of an expansion loop is impractical. Expansion joints are in different shapes and materials. Expansion joints are rubber, metallic, Teflon joints


Hangers used when thermal horizontal movement is a factor with piping?

Expansion joints are typically used when thermal horizontal movement is a factor with piping. They allow for movement in the horizontal direction to accommodate thermal expansion without putting stress on the piping system. These expansion joints can come in various forms such as bellows or slip joints.

What happens to a bridge's expansion joints on a hot day?

If there is no expansion joints on a bridge and if it's really hot the molecules of the bridge will be separated slowly and the bridge will collapse


Why are there joints in bridges?

The space at the joints is there to allow for expansion and contraction of the length of the bridge depending on the temperature.

What is the control joints?

Control joints (often confused with expansion joints) are cut into the concrete or asphalt, and are different from expansion joints as shown in the photo. The joints are cut into the structure at regular intervals allow cracking to occur in a controlled fashion. Road control joints can be sealed with hot tar, cold sealant (such as silicone), or compression sealant (such as rubber).

They are corrosion resistant, non-aging, with extraordinary flex life and unmatched reliability. These superior units cost no more than those made of lesser materials. The flexible element is formed over the full sealing face of the end flanges eliminating troublesome separate gaskets.Note the change in pressure rating with


What is the maximum size a concrete slab can be without the need for expansion joints?

The maximum size for a concrete slab without needing expansion joints is typically around 100 to 150 feet in either direction. Beyond this size, expansion joints are usually necessary to prevent cracking due to temperature changes and shrinkage.
