Due to the variety of hydraulic hose applications and the range of chemicals and pressures they will be subjected to, there are likewise a number of hydraulic hose constructions.
Reinforced: This type of hosing resembles the basic three-layer construction, but with extra buffers in the reinforcement layer, most often in the form of textile braid, wire braid, or wire helix material around the inner tube.
Coiled: Coiled hoses are semi-rigid hoses designed for expansion and easy storing. Because the hose is coiled, it can stretch in such a way that does not put unnecessary pressure on the hose materials.
Corrugated: Another method of increasing expansion and flexibility in a hose is to introduce corrugation. Corrugation manifests as small threads or folds in the material of the hose, somewhat like an accordion, that allow the hose to expand and compress without damaging the housing.
Articulated: Articulated hoses are hoses built in sections, with rigid shafts connected by flexible joints. The articulation allows hoses to turn corners or swivel around other components.
Multi-element: Hoses that involve multiple elements listed above are termed “multi-element hoses.”
