Rubber Hose

Rubber Hose
Rubber plays an important part as hose for conveying fluids or gases. There are a number of different types used depending on the nature of the fluid and the conditions of use. Hose will differ in construction depending on whether it is used at ordinary pressure, under high pressure, or rubber and fabric; or rubber, fabric and metal.
For present consideration, however, they may be divided into the following classes, according to the method adopted for reinforcement;
1. Hose reinforced with fabric used for conveying fluids under moderate pressure.
2. Hose reinforced with braided yarn and used for conveying fluids under moderate pressure.
3. Hose reinforced with wire, used under heavy pressure or strong suction.
For high duty hose, reinforcement with fabric or braided yarn is inadequate. For high pressure or suction work which might cause the hose to collapse, it is necessary to use still stronger reinforcing material such as galvanized steel spiral or braided steel wire.
In a case of suction hose, the steel wire is built in as closely as possible to the interior diameter and most of the fabric is outside this wire, in order to reinforce the hose effectively.
