A rubber expansion joint is an elastomeric tube that is reinforced with multiple plies of fabric. Fabric reinforcement may include solid metal rings or wire embedded in the rubber. The independent layers of rubber combined with fabric reinforcement form a bellow that is vulcanized to hold the joint in place. This bellow helps to prevent the joints from under-compressing or over-extension.
Flexibility is a disadvantage of rubber expansion joints
The flexibility of rubber expansion joints is similar to metal expansion joints in axial plane movements. However, they are less flexible when subjected to lateral motion. For this reason, they are not a good choice for applications where there is a need for extreme lateral movement.
One advantage of metal expansion joints is their resistance to extreme temperatures. They can withstand temperatures as high as 1,800 degrees Fahrenheit. This is more than enough to withstand the pressures and strains that are inherent to the construction industry. On the other hand, rubber is unable to withstand these temperatures.
Control rods prevent overextending or under-compressing of joints
Control rods are a key component in the construction of expansion joints. They function as restraining devices, preventing overextending and under-compressing of the expansion joint rubber expansion joint. They usually consist of a bar or rod that attaches to the expansion joint assembly.
Control rods are also critical in the design of rubber expansion joints. They are used in situations where solid anchors aren’t available. They act as a backup safety device in case the anchors fail.
Rubber expansion joints are becoming an increasingly popular way to connect pipes. They are easy to install and maintain, and are ideal for a variety of situations. Many companies use these flexible construction parts in their processes, including the oil and gas industry, and they are available at reasonable prices. If you’re unsure whether rubber expansion joints are right for your application, contact a professional to find out more.
Rubber expansion joints are available in a variety of designs and materials. Some are used in more rigid piping systems, while others are more flexible. The costs of each will depend on the type of system you’re installing.
Application of rubber expansion joints
The main components of rubber expansion joints are their body and lining. The body is usually made of carbon steel, zinc plated steel, or hot dip galvanized steel. The lining is made of natural or synthetic rubber. The lining provides support and resistance to pressure and movement. The outer flanges are reinforced with solid steel or wire. A leak-proof lining tube extends from the bore to the outside edges of the flanges.
When used correctly, rubber expansion joints can be a high-performance solution for regulating periodic movement and vibration related to temperature changes. Several different designs, materials, and specifications are available.
