Spool / Pipe Expansion Joints


Rubber Expansion Joints

Bi-State Rubber offers spool, flue duct, and pipe expansion joints for most all industrial plants. Bi-State Rubber expansion joints are used in utility or process systems to help control vibration or thermal movement. Our expansion joints primarily use elastomeric material that are resilient, that not only control movement, but also can reduce noise and vibration. We design these expansion joints to be easily installed and be the most cost effective way to control movements through various styles, configurations, and elastomeric materials we have available. The information here is intended to give more details on Bi-State pipe expansion joints as well as connectors and pinch valve sleeves used in these piping systems.

Bi-State pipe expansion joints and connectors can be designed to be used with most any process fluid or slurry. In addition to expansion joints and connectors these systems may also have pinch valves used to regulate flows. These pinch valves may use an elastomeric sleeve similar to a pipe connector that can be squeezed partially closed to restrict flow. Bi-State can be of service on these elastomeric sleeves as well as expansion joints and connectors

Metal Expansion Joints

Metal expansion joints for pipes are available with many different end fitting configurations; including flanges, pipe thread and Victaulic grooved weld on ends. With movement capabilities of ó” up to 16” axial, pressure ratings up to 300 PSI and temperature capabilities of nearly 1500 degrees F, there is a metal expansion joint to fit your application.
