There are types of reinforce for PVC suction hose to enhance the strength. The choice of reinforce depends on the intended use and the level of pressure and vacuum. Here are some common options for PVC suction hose.
Helical Wire
PVC suction hose often features a helical wire reinforce. The wire is typically galvanized steel and is embedded in the wall of the hose. The helical wire makes the hose more strong and durable. Besides, it protects the hose from external impact.
Rigid PVC Helix
Some PVC suction hoses utilize a rigid PVC helix as reinforce. The helix is typically coil or spiral. While the material is normally rigid PVC. This helps the hose maintain its shape.
Polyester Fabric
In some cases, PVC suction hose has a polyester fabric layer. While the fabric increases the hose’s burst strength. Besides, it makes the hose resist high pressure and makes it more durable. While as for the fabric, it can be spiral or braid.
Composite Reinforce
PVC suction hoses can also feature composite reinforce. While this is for special use which requires high pressure ability. For example, the reinforce can be a steel wire with fabric.
The choice of reinforce depends on the special use like the level of pressure, vacuum and work conditions. If you have no idea which one is the best, feel free to consult Orient.
