Expansion Joints are installed in the piping system to absorb vibration and shock. They also have the
Advantage of reducing noise and compensating caused by misalignment.
yes, that is why they put expansion joints on bridges. (: your welcomeyes, that is why they put expansion joints on bridges. (: your welcome
what is the general cost for sealant replacing in expansion joints
Using tar in concrete expansion joints is generally not recommended. Tar can become brittle over time and may not provide the necessary flexibility required for the joints to accommodate movement. Instead, materials specifically designed for expansion joints, such as elastomeric sealants or flexible fillers, are preferred as they can better handle the thermal expansion and contraction of concrete.
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
The space at the joints is there to allow for expansion and contraction of the length of the bridge depending on the temperature.
so they can prevent it from breaking
Expansion joints are typically categorized into several types, including compression joints, which accommodate horizontal movements; tension joints, designed for vertical movements; and hinge joints, which allow angular movement. Other types include sliding joints, which permit lateral movement, and bellows joints, made of flexible materials to absorb thermal expansion and vibrations. Each type is designed to handle specific movement and stress conditions in structures, pipelines, and machinery.
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).

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.
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.
They're called "expansion joints". Concrete expands and contracts with temperature changes. The expansion joints allow this to happen without cracking the concrete slab.
