The Necessity of Expansion Joints
The job of an expansion joint
is hugely important to ensuring the longevity and safety of our buildings, bridges, roads and more. Expansion and contraction of many construction materials - such as brick, concrete, and metal - causes cracking and breakage, which compromises structural integrity and stability. To remedy this problem, we install expansion joints. Expansion joint manufacturers
offer different options and solutions. Each type has its own merits and works best for certain structures, so which kind should you choose for your project?
The Strong Points of Metal Expansion JointsMetal expansion joints
compensate thermal expansion and other movement in containers, pipelines, and machines. Today, metal expansion joints consist of multi-ply bellows (multiple thin plies of metal), which increases flexibility and stability. Consisting of inner and outer stainless steel cylinders (between which exists a spiraled, open cylinder creating multiple plies), multi-walled stainless steel expansion joints
contain multiple welded cylinders to form closed and pressure-tight walls. Advantages of these metallic expansion joints
include, but are not limited to: absorption of large movements, early indication of leakage, ability to withstand high temperatures, and resistance to high pressure.
The Benefits of Rubber Expansion JointsRubber expansion joint manufacturers
can produce their products in multiple ways: manually wrapping fabric reinforced rubber sheets, which is labor intensive but allows wires or rings to be added for additional reinforcement; molded rubber expansion joints, mostly for large quantities of the same joint; and automated winding of rubber expansion joints
, which is the newest technology and provides accurate, fast, and consistent quality. Unlike stiffness of metal expansion joints, rubber expansion joints have higher lateral motion and produce less undesirable noise caused by vibration. To further protect the joint's expansion, joint cover manufacturers
offer a product designed to insulate bellows and protect from internal damage. These removable or permanent covers increase the longevity of expansion joints, possibly saving money down the line.
