PVC spiral reinforced hose is a hose with a spiral engineering plastic skeleton embedded in the PVC tube wall. This design is not for the pursuit of extreme mechanical strength, but to obtain special properties such as corrosion resistance, lightweight, and non-magnetic properties.
Different types of suction hose
For this spiral suction hose, the composite process of the plastic spiral and the PVC pipe body is extremely demanding. It is necessary to ensure that the plastic spiral and the PVC material are perfectly bonded during the heating and cooling process without delamination or separation.
100% corrosion resistance, never rusts:
This is its core advantage. Whether conveying corrosive chemicals or acidic liquids, or in humid, salty environments (offshore and in aquaculture), it is completely immune. Unlike steel wire, it will not corrode or rust, contaminating the media or causing the reinforcement layer to fail.
The advantage of steel wire tubing lies in its exceptional mechanical strength and durability, making it suitable for handling harsh physical environments.
Even when crushed by wheels or heavy objects, it quickly rebounds and is less likely to be permanently crushed.
Advantages
Excellent Flexibility and Elasticity
The plastic spiral gives the hose excellent flexibility and resilience, making it easy to bend and coil. It also maintains its flexibility even in low-temperature environments and resists hardening.
Excellent Insulation
The entire hose is made of plastic, which offers excellent electrical insulation properties, making it suitable for specialized applications requiring insulation.
Hose Specification
Technical Specifications (Typical Range)
Working Pressure: Typically approximately 4-8 bar (positive pressure)
Vacuum: Approximately -0.6 to -0.8 bar (negative pressure, sufficient for most suction needs)
Temperature Range: Approximately -10°C to +60°C (temperature resistance depends on the PVC formulation; some models can reach +80°C)
Inner Diameter Range: Commonly available from 25mm (1″) to 150mm (6″), and even larger
Hopefully, the above information about PVC spiral reinforced hose can help you make the appropriate choice based on your actual application scenario.
