Roof Covers.Proco Style RE wide arch expansion joints are built to withstand even the most rigorous piping system configurations. They allow for axial compression or axial extension, and lateral deflection as well as angular and torsional movements.

For more information about the features and benefits of the Proco Style RE, download our brochure. All products are reinforced with Polyester Tire Cord 1. All elastomers above are not intended for steam service. Nominal I. Angular 4 Deflection Degrees. Torsional 5 Rotation Degrees. Concurrent Movements — Concurrent movements are developed when two or more movements in a pipe system occur at the same time. If multiple movements exceed single arch design there may be a need for additional arches.

To perform calculation for concurrent movement when a pipe system design has more than one movement, please use the following formula: Calculation must be equal to or less than 1 for expansion joint to operate within concurrent movement capability.

At higher temperatures, the pressure rating is reduced slightly.

Hydrostatic testing at 1. Weights are approximate and vary due to length. The degree of angular movement is based on the maximum rated extension. Torsional movement is expressed when the expansion joint is at neutral length. Calculation of Thrust Thrust Factor. When expansion joints are installed in the pipeline, the static portion of the thrust is calculated as a product of the area of the I.

The result is a force expressed in pounds. Take design, surge or test pressure X thrust factor to calculate end thrust. For filled arch configuration use the I. Vacuum rating is based on neutral installed length, without external load. Limit rod unit weight consists of one rod with washers, nuts, and two limit rod plates. For plastic pipe systems utilizing the series RC, consult Proco for design considerations. Larger sizes not shown in brochure are available upon request.

Each In-Line Pressure Balanced Expansion Joint is designed for a specific pressure, temperature and axial compression rating. The most common fitting configurations are flanges or beveled weld ends. Elbow Pressure Balanced Expansion Joints. This expansion joint is similar to the tied universal expansion joint with balancing bellows that almost totally eliminates the pressure thrust on the anchors.

This metal expansion joint design is recognized and recommended by the Expansion Joint Manufacturers Association. Externally Pressurized Expansion Joints. Externally Pressurized Expansion Joints are the perfect choice for large amounts of axial compression or extension. Other benefits of an externally pressurized expansion joint are that they have a built-in guiding system eliminating the need for the first pipe guide in a piping run.

For steam applications, where usually a flow liner is required, externally pressurized expansion joint, due to its construction eliminates this requirement. This type of metal expansion joint also incorporates an outer casing to contain the pressure which also protects the metal bellows from damage. Universal Expansion Joints. This expansion joint design will accept large amounts of lateral offset in multiple planes.

The amount of deflection is based on the amount of angulation each bellows can take and the length of the center spool. The designers at Triad Bellows can increase or decrease the lateral deflection capability and cycle life by changing the center pipe length.

Proco Style RE-231

These expansion joints do not use tie rods and require the system piping to be properly anchored. Tied Universal Expansion Joints. With the addition of tie rods this metal bellows expansion joint does not require main anchors in the pipe run.
