About Pipe Expansion Joints

Select the right expansion joint by measuring the size of your pipes and comparing types of joint movement.

Pipe Expansion Joints with Flanged Ends

Shown Installed on a Flanged Pipe

These joints reduce stress, vibration, and noise in piping systems by providing a point of flexibility to absorb movement. The flanged ends rotate for easy bolt hole alignment during installation. They mate with a same-size flat-surface Class 150 flange without the need for a gasket. Joints have a flexible body that is reinforced with nylon for added strength.

Position the expansion joints as close as possible to anchor points.

Expansion Joint	Limit Rod

Limit Rod Sets—Attach limit rod sets (sold separately) to the flanges to prevent overextension where anchoring is insufficient. To accommodate the thickness of the limit rod mounting plate, use bolts that are _7/8" longer than the bolts connecting the expansion joint to the pipe flange. Each set of limit rods requires eight bolts (not included).

High-Temperature All-Metal Pipe Expansion Joints with Flanged Ends

These all-metal expansion joints can handle higher temperatures than rubber expansion joints. They reduce stress, vibration, and noise in piping systems by providing a point of flexibility to absorb movement. Joints are made of 304 stainless steel for very good corrosion resistance. The flanged ends rotate for easy bolt hole alignment during installation. Flanges mate with a same-size flat-surface Class 150 flange with a gasket (sold separately).

Pipe Expansion Joints with Butt-Weld Ends

These joints weld to unthreaded pipe or another butt-weld fitting for a leak-resistant, permanent connection. They reduce stress, vibration, and noise in metal piping systems by providing a point of flexibility to absorb movement.

Pipe Expansion Joints with Flanged Ends for High Vibration

Shown Installed on a Flanged Pipe

These expansion joints have a double-bulb design for extra movement and vibration absorption. The flanged ends rotate for easy bolt hole alignment during installation. They mate with a same-size flat-surface Class 150 flange without the need for a gasket. Joints have a flexible body that is reinforced with nylon for added strength.

Clamp-On Pipe Expansion Joints

Slip these joints over your pipe ends and tighten the band clamps for a secure hold. Joints have a triple-bulb design that provides excellent vibration absorption to reduce stress on your piping system. They also have reinforcing rings for extra support during pressure surges and in vacuum applications.
