You’ve likely seen rubber hoses reinforced with steel wires-these versatile tools power countless applications. Let’s break down what they are and how to use them safely.
What Are Steel Wire Rubber Hoses?
These hoses feature three layers: an inner rubber layer, a steel wire reinforcement, and an outer rubber layer. They come in various types, each tailored to specific tasks:
For general water use in temperatures ranging from -20°C to 60°C.
Rubber Air Hose
A high-pressure hose designed for compressed air and inert gases.
Oil-Resistant Hose
Transfers petroleum, fuel, and lubricants. Also functions as a rubber fuel pipe.
High-Temperature Resistant Hose
Examples include EPDM steam hoses, which handle steam and hot water up to 200°C.
Acid-Resistant Hose
Chemical hoses that safely transfer 80% of acids, alkalis, and solvents.
Sand Blasting Hose
Identical to shot blast hoses, used to spray abrasives for metal surface cleaning and rust removal.
Safe Usage Tips
Follow these steps to maximize performance and safety:
Respect Temperature Limits
Use the hose within the temperature range specified by the supplier. High temperatures accelerate aging.
Select Correct Fittings
Ensure fittings match the hose size. Shape the hose properly during assembly to prevent leaks.
Check Stability Regularly
Verify that fittings and assemblies are secure. Inspect hoses routinely for wear.
Store Properly
After use, store hoses in a dry, well-ventilated area away from direct sunlight.
