Steam Hose
About Steam Hose
A steam hose is a specialized rubber hose designed to convey saturated or superheated steam under high pressure and extreme temperatures. According to industry standards, a genuine steam hose must withstand continuous operating temperatures from -40°C to +210°C (-40°F to +410°F) while maintaining structural integrity and safety. Typical applications include steam cleaning, oil tank heating, construction curing, chemical plant maintenance, food processing, and rubber vulcanization lines.
Specifications for Steam Hose
| Parameter | Range |
|---|---|
| Inner Diameter (ID) | 3/8 inch to 4 inch (10mm to 102mm) |
| Working Pressure | Up to 300 psi (saturated steam) / 600 psi for high-pressure variants |
| Burst Pressure | 4x safety factor (minimum 1200 psi) |
| Temperature Range | -40°C to +210°C continuous |
| Safety Factor | 4:1 (static) or 10:1 (steam service recommended) |
Construction & Material Layering
Inner Tube: EPDM synthetic rubber or CR chloroprene rubber – provides exceptional heat, steam, and oxidation resistance. Smooth bore minimizes flow resistance and prevents scale accumulation.
Reinforcement Layer (Core Strength):
Wire Braided Hose (1 or 2 layers): High-tensile steel wire braid offers flexibility with moderate pressure capacity. Ideal for steam cleaning guns and mobile equipment.
Wire Spiral Hose (4 or 6 layers): Alternating spiral-wound high-carbon steel wires deliver superior burst resistance and impulse endurance. Best for stationary industrial steam lines with repetitive pressure spikes.
High Pressure Steam Hose: Combines spiral reinforcement with specially compounded heat-resistant rubber to handle both pressure and thermal cycling.
Cover: Pin-pricked EPDM or CR rubber cover – allows trapped gases to escape during steam service, preventing blistering. Resists abrasion, ozone, weather, and mild chemicals. Standard color: red or black.
Performance Features & Advantages
Pulse Performance: Exceeds 200,000 impulse cycles under dynamic steam pressure, verified by our in-house pulse test rig.
Media Resistance: Unaffected by steam, hot water, mild acids, alkalis, and ozone. Not for oil-based fluids.
Bend Radius: Minimum bend radius ranges from 5x ID (for braided) to 8x ID (for spiral). Flexible yet kink-resistant.
Durability: Cover passes 10,000+ cycles of abrasion resistance (DIN 53516). Excellent UV and weather aging.
Standards Compliance: Manufactured to EN 853, EN 856, SAE 100R1, SAE 100R2, and ISO 6134 (steam hose specific).
Standards & Certifications
Our steam hose carries:
ISO 6134 Type 1 & 2 (saturated steam up to +210°C)
SAE 100R6 / R7 (low-pressure steam applications)
BS 5342 (British standard for steam rubber hose)
China GB/T 3683 (national standard)
Certifications: ISO 9001:2015, MSHA (mine safety approval for underground use), SGS factory audit
We benchmark all performance metrics against Parker, Gates, and Eaton – ensuring our steam hose delivers comparable reliability at competitive price.
Application Scenarios & Industry Coverage
Construction: Concrete curing, asphalt heating, form cleaning
Marine: Boiler blow-down, tank cleaning, deck steam cleaning
Manufacturing: Rubber vulcanization, food equipment sanitation, textile mill humidification
Oil & Gas: Heavy oil heating, pipeline preheating
Chemical Plants: Reactor cleaning, heat tracing

Selection and Usage Considerations
How to Choose the Right Steam Hose
Define steam type: Saturated (wet) or superheated (dry)? Use ISO 6134 Type 2 for superheated.
Measure max temperature: Never exceed 210°C continuous. For intermittent, allow cool-down cycles.
Check working pressure: Add 20% safety margin for pressure spikes.
Select end connections: Crimped fittings (permanent, leak-proof) vs. reusable fittings (field-replaceable). Common adapters include NPT, BSP, JIC, and flanges.
Consider protection: Add protective sleeves or guards for high-traffic areas to prevent abrasion and steam burns.
Installation & Safety Warnings
Never use general-purpose air/water hose for steam – catastrophic failure risk.
Avoid bending below minimum radius (see spec table).
Install with proper steam hose fittings rated for temperature and pressure.
Use slow warm-up (5-10 minutes) to prevent thermal shock.
Regularly inspect cover for blisters, cuts, or exposed wire.
Maintenance Checklist
Monthly: Visual check + gentle flex test.
Quarterly: Pressure test to 1.1x WP.
Annually: Replace if cover shows cracking or reinforcement corrosion.
