Expansion Joints

Smith-Blair Expansion Joints are carefully designed and manufactured according to specific engineering requirements. Each expansion joint consists of a slip pipe that telescopes within a body to compensate for changes in the length of a pipeline. The body of the expansion joints has a packing chamber containing resilient packing to form a seal between the body and the slip pipe.

Steel Couplings

Smith-Blair Steel Couplings offer many distinct advantages when installed in a piping system. Properly selected and installed felxible couplings maintain the continuity of the pipe system, retain the line contents under internal pressure and prevent infiltration under vacuum. Our couplings consist of one cylindrical sleeve with conical inner surfaces at each end; two resilient, wedge-shaped, specially-compounded rubber gaskets; two ring-shaped followers and a set of high-strength, low-alloy track-head, oval-neck, rolled-thread bolts with heavy hex nuts.
