Description
Series J-1 & J-1 Wide Arch Redflex Flanged Expansion Joints are used to compensate for pipeline movement and vibration. The construction of a Redflex Expansion 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 middle layer of the joint contains the bias-ply synthetic fabric reinforcement that gives the joint its form and pressure rating, and a layer 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 Expansion 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, allow the J-1 to provide stress relief in piping systems due to thermal expansion and contraction, mechanical movements and vibration. Special multiple arch designs, filled arches and wide arches are also available.
