EPDM High Temperature Steam Hose 230℃

Product Overview

Definition and Standard: The EPDM High Temperature Steam Hose 230°C is a specialized synthetic rubber hose designed for saturated and superheated steam transfer. As a leading manufacturer in China, this hose meets rigorous international standard requirements, providing a reliable solution for industrial steam applications where safety and durability are critical. Its definition as a high-performance steam hose centers on its ability to handle extreme thermal cycles without degradation.

Core Structure: This Wire Braided Hose features a seamless EPDM tube, one or two layers of high tensile steel wire braiding for reinforcement, and a pin-picked smooth EPDM cover, ensuring a wrapped finish that resists blistering.

Key Performance Parameters: With a working pressure of 250 PSI / 17 Bar and a burst pressure of 2500 PSI / 172 Bar, it offers an industry-leading 10:1 safety factor. It operates continuously from -40°C (-40°F) to +230°C (446°F), with an instantaneous tolerance of 250°C (482°F).

Core Advantages: First, the 10:1 safety factor provides exceptional protection against pressure spikes. Second, the pin-picked cover allows steam to permeate safely, preventing surface blisters. Third, the EPDM compound resists oxidation, ozone, and weathering. Fourth, it maintains flexibility even at extreme temperatures, reducing installation stress.

Main Applications: This High Pressure Hose is ideal for steam cleaning, vulcanizing presses, refinery plants, food processing lines, and construction equipment where high-temperature steam is used.

Addressed Pain Points: It solves catastrophic hose bursts, short service life from heat aging, cover blistering due to steam entrapment, and the high cost of frequent replacements and downtime.

Quality Commitment: Backed by strict factory supply quality control, this rubber hose is traceable by batch. As a trusted supplier, we provide support for OEM ODM projects, ensuring long-term service and performance.

Structure and Materials

• Tube (Inner Layer): Smooth EPDM synthetic rubber – provides superior heat resistance and prevents steam from degrading the reinforcement.
• Reinforcement: High tensile steel wire braiding – delivers the 2500 PSI burst strength while maintaining flexibility.
• Cover (Outer Layer): Red or blue EPDM rubber, pin-picked smooth with a wrapped finish – resists weather, ozone, and cover blistering.

Engineering Insight: Why a 10:1 Safety Factor for Steam?

Unlike hydraulic applications that typically use a 4:1 safety factor, steam hoses require a much higher margin. Steam is a compressible medium that expands rapidly during pressure drops. If a steam hose bursts at a lower safety factor, the explosive release of latent heat and volume expansion can cause catastrophic injury. Our EPDM High Temperature Steam Hose 230°C maintains a 10:1 ratio, ensuring that even under repeated pressure spikes or superheated conditions, the Wire Braided Hose structure remains intact.

Application Industries

This High Pressure Hose is engineered for mission-critical steam transfer across multiple sectors.

• Construction & Engineering Companies: Steam curing of concrete panels, asphalt heating, and equipment cleaning.
• Facility Management: Steam boiler systems, HVAC humidification, and industrial sterilization.
• Food Processing Plants: Sanitary steam for cleaning production lines and equipment.
• Rubber & Tire Manufacturing: Vulcanizing presses and mold heating.
• Petrochemical Refineries: Tank cleaning, pipe thawing, and process heating.
• Marine & Shipyards: Deck steam cleaning and cargo tank heating.

Precise Selection Professional Guide

It Is More Than a Hose – Complete Hose Assembly Solution

A hose assembly integrates the hose with compatible connection systems. For this EPDM High Temperature Steam Hose 230°C, we recommend:

• Crimped fittings: Permanent, leak-free connections for high-temperature steam.
• Reusable fittings: Field-attachable for maintenance flexibility.
• Adapters: BSP, NPT, or flange conversions.
• Flanges: For large-bore (2″ to 4″) permanent installations.
• Protective sleeves & guards: Fiberglass sleeves to prevent external abrasion and heat transfer to operators.

All hose assembly work is performed with certified crimping machines and pressure-tested before delivery.

Industry Pain Point Solutions

Pain Point: Frequent hose bursts on steam vulcanizing presses.
Our Solution: The 10:1 burst safety factor and high tensile wire braiding absorb pressure spikes from rapid valve closures.

Pain Point: Cover blisters after 2 weeks of use.
Our Solution: The pin-picked smooth cover allows entrapped steam gases to escape, eliminating blister propagation.

Pain Point: Hose stiffens and cracks in cold startup (-30°C).
Our Solution: The EPDM compound stays flexible down to -40°C, reducing bending force and installation damage.

Technical Standards and Certifications

• Standard: Meets or exceeds international standard requirements for steam hoses (ISO 6134 Type 2).
• Safety Factor: 10:1 (burst : working pressure).
• Certifications: Available upon request – test reports from accredited labs.
• Traceability: Each hose batch is date-coded for full support and recall management.

Brand and Quality Assurance

As a factory and professional producer of industrial rubber hose products in China, we integrate quality at every stage.

• Incoming Raw Material Inspection: EPDM compounds and high tensile steel wire are tested for tensile strength and heat aging.
• In-Process Control: Extrusion, braiding, and vulcanization parameters are monitored in real-time.
• 100% Factory Testing: Every length undergoes a hydrostatic proof test at 1.5x working pressure before shipping.
• Laboratory Validation: Burst tests, impulse cycle tests, and ozone resistance tests are performed quarterly.

Third-Party Verification: We provide pdf copies of independent lab test reports confirming the 2500 PSI burst pressure and 10:1 safety factor.

Sustainability: Materials are RoHS and REACH compliant. The long service life reduces replacement frequency and industrial waste.

Installation, Operation, and Maintenance Guide

1. Installation: Always use crimped fittings or reusable fittings rated for steam. Install with a minimum bend radius (see specification table). Never exceed the B.R.
2. Operation: Warm up the hose gradually with low-pressure steam for 2-3 minutes before full pressure. Avoid sudden valve opening.
3. Maintenance: Inspect the cover weekly for cuts or blisters. Replace immediately if any wire reinforcement is visible.
4. Storage: Store in a cool, dry area away from ozone sources (motors, transformers). Use protective sleeves near sharp edges.
5. Safety: Always use guards near operator stations. Depressurize completely before disconnecting fittings.

Frequently Asked Questions (FAQ)

Q1: Can this EPDM High Temperature Steam Hose 230°C be used for hot water?
Yes, it is fully compatible with high-temperature hot water up to 230°C.

Q2: What is the difference between wire braided and wire spiral hose for steam?
Wire Braided Hose (this product) offers flexibility and is ideal for steam. Wire Spiral Hose is typically for ultra-high pressure hydraulic applications (4000-6000 PSI) and is less flexible.
