They are generally larger and thicker than rubber tubes and are used in more demanding applications. Rubber hoses are important industrial utilities; they are used for the transmission of hydraulic fluids, fuel and other important ingredients in industrial processes and equipment.
Among other applications, rubber hoses are used as fire control equipment in large industrial complexes. Industrial rubber hose tends to be highly durable, reinforced and abrasion resistant. Rubber hose manufacturers make hoses that can withstand extreme temperatures and high pressures. In addition to the long list of industrial rubber hose utilities, rubber hoses are also valued in consumer products contexts, particularly in their capacity as lawn and garden watering tools. Rubber hose can be used as a connector between two enclosed spaces or for suctioning, venting or spraying gas or liquid into a certain area.
Some offerings from rubber hose manufacturers include truck or aircraft fueling hose, vapor recovery hose, aggressive chemical transfer hose, chemical food quality hose, oilfield vacuum hose, concrete placement/pump/plaster hose, heavy duty dock hose, dredging hose, fire engine suction and discharge hose, crush and kink resistant food/beverage suction hose, marine exhaust/fuel hose, military spec hose and many other examples.
Rubber hose can be fashioned from a wide variety of raw materials. These include white FEP, nitrile, SBR, chlorobutyl, modified cross-linked polyethylene, multiple layers of polypropylene, PVC coated polyester, EPDM, Viton®, natural latex and many other materials. Rubber hose can be made in several ways, and rubber extruding is among the more prominent of these methods. Rubber extrusion involves the use of an extrusion die to create a usable rubber product.
The process begins with a collection of raw rubber materials in a hopper suspended above a conveyance channel. When the rubber is released into the channel, it is forced down the channel by a long, turning shearing screw. As the screw turns, it generates friction and pressure that cause the rubber to become molten. Once molten, the rubber is ready to be forced through the extrusion die. An extrusion die is a specially shaped hole cut in a metal plate that gives shape to materials that are forced through. When the raw material emerges on the other end of the extrusion die, it is newly extruded rubber hose. The hose is then cut to the appropriate length and either prepared for shipment or sent for additional processing if necessary.
