Hydraulic components - Pipes and fittings

Videos

Just like a hose you might use to water your garden, the purpose of a hydraulic pipe is to allow fluid to flow from one component to another – in this case hydraulic fluid. The pipe is the conduit that ensures the fluid is able to travel unimpeded and it’s a vital part of keeping hydraulics systems moving. In fact, if a hydraulic pipes was to fail it can bring entire production lines to a standstill and take vital machinery offline until the hose can be replaced.

Types of hydraulic pipes:

Synthetic rubber Fluor polymer Thermoplastics Stainless steel

Reinforcement:

This is the strength of hydraulic hose. It’s the reinforcement that determines the working pressure of the hose. Hydraulic hose is defined by its pressure capacity, so pressure determines how the hose is constructed. The more layers in the reinforcement, the higher the pressure rating. It’s typically braided, spiral or helical and is made from single or multiple sheaths of braided wire, textile yarn or spiral-wound wire.

Variables that influence pipe selection:

The type of fluid passing through the hose The operating conditions the hose will be subjected to (pressure/temperature) Hose size (diameters and length) Hose flexibility and durability Ends and couplings (what the hose will be attached to)
