Profile: Sadhanaflow Technology is specialized in providing process equipment and control solutions. We offer chemical process pumps, flow measurement & control equipment, metallic expansion bellows/joints/compensators, and corrugated hoses. Hinged bellows contain hinges or pivots which cause the unit to bend in a single plane. Normally these units are prevented by their design from deflecting axially, either in extension or compression. Their hinge mechanisms are usually designed to accept the full pressure thrust. Some hinge types can be provided with hinge pin holes which are slotted to permit limited axial travel.
