Flanged Expansion Joints
Enquire about this Product
The Redflex® Expansion Joint is used to compensate for pipeline movement and vibration. The construction of a Redflex® joint is very much like a heavy-duty truck tire: layers of high-quality elastomers are reinforced with steel wires and synthetic fabrics.
The inner layer forms a tube that extends through the inside of the joint, and across the face of the end flanges. This layer is chosen based on its chemical compatibility and abrasion resistance and temperature rating to the process material. The T-205 Redflex® Expansion Joint is supplied with a solid Teflon® Lining for maximum chemical resistance.
The middle layer of the joint contains the bias-ply synthetic fabric reinforcement that gives the joint its form and pressure rating, and a layer(s) of wire reinforcement for added strength.
The outer layer of the joint is chosen to be compatible with the environment in which the joint is to be installed, usually Neoprene or Butyl. This allows the joint to stand up to occasional contact with oils, corrosion, and weathering.
Redflex® Expansion Joints features full-face integral flanges that eliminate the need for additional gaskets when installing the joint. The flanges are drilled to mate with ANSI 125/150 flanges, with special drilling available upon request. Galvanized or stainless steel retaining rings can be provided to protect the flange and distribute forces evenly. Redflex® Joints can also be manufactured to meet Coast Guard and Military standards as well.
Redflex® Expansion Joints are available with a single arch, double arches, or triple arches to meet the face-to-face and movement requirements of the installation. The arches, along with the flexibility of the elastomer construction, allows the J-1 to provide stress relief in piping systems due to the thermal expansion and contraction, and mechanical movements and vibration. Special multiple arch designs, filled arches, and wide arches are also available.
