Precautions when using rubber oil hoses
Steel wire rubber hoses come in different specs, each handling unique pressure ranges. But how do you assess a rubber hose’s pressure resistance? In fact, you can judge it based on several key factors. Let’s break them down.
Thickness of the Inner Rubber Layer
A thicker inner rubber layer means better pressure tolerance. Typically, inner rubber layers range from 0.5mm to 1.5mm thick. Hoses with these thicknesses can handle 0.5MPa to 1.5MPa of pressure.
Diameter of the Steel Wire Reinforcement Layer
Larger steel wires in the reinforcement layer boost pressure resistance. Most steel wires here measure 6mm to 16mm in diameter. Hoses with these wires can handle pressures from 0.5MPa up to 4MPa.
Material of the Outer Rubber Layer
The outer rubber material also affects pressure-bearing capacity. Natural rubber and nitrile rubber, for example, excel at handling higher pressures compared to other materials.
Reinforcement Type
Beyond material and wire diameter, reinforcement type plays a big role in pressure resistance.
There are several common types:
Standard steel wire rubber hoses handle 0.5MPa to 1.5MPa.
Reinforced steel wire hoses step up to 1MPa to 4MPa.
Steel wire spiral hoses outperform the first two, with a range of 2MPa to 8MPa.
High-performance spiral hoses offer the best resistance, handling 2MPa to 10MPa.
These are the pressure resistance specs for various rubber hoses. At Orientflex, we offer a wide range of pressure-resistant hoses—all high-quality and cost-effective. Contact us today to get the best quotation.
