Joint Types

Standard Spool Type 

Style 9030-Pressure Only

Style 9060-Pressure and Vacuum

This is the basic expansion joint that fits the majority of applications. This style can be adapted for many different applications, depending on service conditions. Available with a filled arch* or open arch and in variable face to face dimensions. Modification to standard design can increase pressure and temperature ratings.

 

Multiple Arch Type

Style 9030-Pressure Only

Style 9060-Pressure and Vacuum

For greater movement where face to face dimensions are not limited. Same allowable pressures as standard single arch. Highly flexible. To compute permissable movement, multiply capacity of comparable single arch by the number of arches. No more than four are recommended.

 

Eccentric and Concentric Reducers

Style 9030-Pressure Only

Style 9060-Pressure and Vacuum

To connect flanges of different diameters, parallel or offset, especially in centifugal pump installations. Available Variations: Filled arch*, no arch, oversize arch, special linings, and straight section on smaller end to insure bolt clearance. We can provide tooling rapidly for special applications.

 

Vibr Joint Type

Style 15 150PSI

Style 25 250PSI

Wire-Reinforced Flexible Connectors

Vibr Joint flexible connectors insulate piping systems from vibration and the noise of water hammer and pulsating equipment. The body is constructed of multiple plies of high strength, rubberized fabric, reinforced with spirally wound high tensile wire embedded in the wall. Liner and flanges are high quality elastomers. Full faced flanges are integral with the body. Standard lengths vary with pipe size. Recommended length for effective vibration dampening is 18" face to face. Also available with Navy Flanges for shipboard use.

U.S. Navy Expansion Joints Style 9090

In Accordance with Mil. Spec. E 15330

Used extensively aboard Navy ships, the style 9090 is similar in configuration to the standard spool type, except that strict material specifications for fire retardance are adhered to. In addition, Navy flanges and drilling are different from standard commercial flanges. La Favorite expansion joints have been installed on many U.S. Navy combat and support vessels and because of their high quality, have been specified for use on the world's largest nuclear powered aircraft carriers.

*Note: A filled arch reduces movement limits by 50%
