The Hydra-Loc™ Tube Sleeving System hydraulically expands the sleeve into intimate contact with the tube and locks the sleeve in place. The Hydra-Loc process offers the following benefits.

• The Hyrdra-Loc process is faster than conventional roller expansion techniques.Because the expansion pressure is tightly controlled the hydra-Loc process eliminates damage to the host tube and tube-to-tubesheet joints caused by over-rolling.
• The Hydra-Loc's hydraulic expansion process allows the sleeve to expand and conform to the actual contours of the host tube end regardless of how eroded the tube has become.

When selecting sleeves choose a sleeve material that is similar to the parent tube material, or upgrade to a tougher alloy to reduce future erosion.

The length of the sleeve should be selected so that the sleeve extends a few inches beyond the most severely damaged portion of the tube end. Standard sleeve lengths of 6", 8" and 10" are the most common, longer sleeves are available upon request. The Hydra-Loc process can be used on all sleeve materials and lengths.

Full length tube liners are available on request.
