Thermoplastic hoses are common in both mobile and industrial equipment, and they are widely used in medium-to-high pressure hydraulic applications. Related products are often specified for handling compressed air and other gases, transporting chemicals, and in water-cleaning and paint-spray operations.
Like its rubber counterpart, thermoplastic hydraulic hose typically has an inner tube, one or more layers of reinforcement, and a protective cover. Where they differ, as the name implies, is in the materials of construction.
Thermoplastic hose also generally has one or two reinforcing layers that provide needed strength and adequate pressure-holding ability. The reinforcement layers usually have a braided construction, made from materials like polyester, polyamide or aramid fibers, or steel wire.
For users, thermoplastic hose offers a number of benefits over rubber hydraulic hose. As mentioned above, these products can be formulated to easily handle extreme temperatures and environmental attack that would prematurely degrade rubber hoses.
The tube typically has a smooth internal surface that permits highly efficient flow and reduces flow losses. It also tends to offer low expansion even at maximum working pressure. And the plastic tube resists erosion, which helps maintain overall system cleanliness. Another benefit is that during the production process, thermoplastic hose has a self-supporting inner tube that is cured without a mandrel. (In contrast, rubber hose is manufactured on an internal mandrel that provides support and maintains tube dimensions during processing, and it must be subsequently removed.) Therefore, thermoplastic hose can be made in extremely long lengths. Some special offshore applications take advantage of continuous hose in lengths of up to 8,000 meters.
