Our steam service ratings are very low in the interest of safety although our 70°F (21°C) pressure ratings are as high or higher then our competitors. All locations where failure could lead to personal injury or suffocation must be avoided. In dangerous locations we suggest housed expansion joints, solid loops, ball joints, packed devices, etc. rather than thin-walled flexible products regardless of manufacturer.

Consult factory with full location description as well as service conditions for higher pressure or temperature applications.

All Restrained Flanged Bellows are designed for 1″ (25mm) Compression, 3/8″ (9mm) Elongation and 1/8″ (3mm) Transverse movement. If piping is not anchored, the pressure will open the joints 3/8″ (9mm). When proper anchors are installed, movements will take place as required.
