Armoured hoses are used in dredging, marine aggregates, harvesting, offshore oil and gas operations and in navigation. It is wear and cut resistant due to the many steel rings embedded in the high quality rubber. This makes it ideal for suction applications and for use in deep-sea operations because of its ability to withstand high outer pressures without deformation. It supports a wide range of marine transportation problems.

Axial expansion joints are designed for axial movement only, though in certain circumstances will accommodate a small lateral offset. These expansion joints do not restrain the internal pressure thrust. The piping designer must provide the system with separate anchoring and guiding to resist the pressure thrust. Where small thermal movements are involved and proper anchoring and guiding is feasible, a single expansion joint is the most economical installation.
