Expansion gland

An expansion gland is a movable pipe connection that absorbs and compensates for movements in the pipes during operation. In contrast to other expansion joints , which usually consist of one piece, here a movable pipe section is fitted into two pipe ends. The individual ends are sealed with stuffing boxes . The expansion gland can only compensate for movements in the direction of the pipe.

The expansion gland is therefore suitable for installation in large heat exchangers with high temperature differences. Another application is the use in movable pipe bulkheads or pipe penetrations .
