Why to use Composite Hose?

by Kristen White Blogger

Composite hoses are different from other single-material hoses. The construction of these hoses is based on the mandrel-wrapped principle, in which the hoses are in the form of a helix. They are made from multiple ranges of tight-wound polyester, polypropylene, polyamide fabrics, and films, reinforced in one single tube in the shape of inner and outer wire helixes. Fabrics and films are covered and protected with the help of PVC coated fabric. This hose possesses capabilities such as versatility and adaptability, making it flexible to use for a variety of industrial purposes.

Inspection and Testing of Composite Hose

To ensure trouble-free service when looking for Composite Hose, it should pass visual inspection, hydrostatic testing, and age retirement criteria.

1. Visual Inspection: Retirement criteria depending upon visual inspection comprises the following:

• If an outer wire is corroded.

• If adjacent inner or outer wire got dislocated.

• Wear and tear in the body of the hose and on the inner and outer wire.

2. Hydrostatic Test: Best flexible hose manufacturer performs the hydrostatic test along with electrical continuity as described below:

• The hose should be laid straight to allow free pressure movement.

• After placing the blanks over both ends, the hose should be filled with fresh water.

• While examining for leaks, pressure should be raised to 345 kPa.

• Hold the same for 10 minutes and after that, check the electrical continuity.

Reasons for using Composite Hose

Composite hose is considered the most versatile hose for industries because it can transfer a large variety of chemicals and fluids. It also comes with other special properties hence making it popular in the industry market.

1. Flexibility: Composite hose is considered the most flexible hose. Multiple layers of fabrics and films used in the designing of this hose are not sealed or glued together. This gives the ease of bending as the layers can easily slide over one another when the composite hose is moved.

2. Safety: Composite hose is usually fabricated to be fail-safe. Basically, there are two areas where this hose can fail:

• The Hose: Directly, there is no leak path present in the hose for the liquid to follow because of the multiple layers of fabrics and films. For the leak to occur, the fluid must find its way through these multiple layers until it reaches the outer layer. After reaching the outer layer, small drops could be seen along the seam line showing that a leak had taken place. Whereas, in other hose, leaks are usually fatal, damaging the walls of the hose without any prior warning.

• The End Fitting: They are specifically designed in the shape of a tailpiece or spiral shank, which reduces the chance of a fitting blowing off on their own.

3. Chemical Resistance: The bore of the composite hose is designed using a wide array of plastics such as Teflon, polypropylene, and nylon, which can accommodate a large variety of chemicals. This makes composite hose suitable for the transfer of chemicals.

Conclusion

Hose pipes are generally used in homes and industries. For the home applications, we are free to choose any hose, but for industrial purposes, the composite hose is the most preferred one.
