Why Metal Pressure Hoses?
Metal pressure hoses are known for their ability to handle extreme temperatures, high-pressure environments, and corrosive substances. Unlike rubber or plastic hoses, metal hoses can operate in severe conditions while providing long service life and excellent reliability.

Benefits include:

Resistance to high pressures and temperatures

Flexibility with durability

Compatibility with aggressive chemicals

Fire and moisture resistance

Longevity in demanding environments

However, improper hose selection can lead to system inefficiencies, frequent maintenance, or even dangerous failures. That’s why selecting the right hose is not a one-size-fits-all decision.

1. Understand Your Application Requirements
Start by thoroughly analyzing your operation. Ask the following questions:

a. What is the medium being conveyed?
Identify whether the hose will carry gases, liquids, steam, or slurries. Know the chemical nature of the medium—corrosiveness, abrasiveness, viscosity, and toxicity. For example, transporting acidic chemicals will require a hose material with high corrosion resistance like stainless steel 316L.

b. What are the pressure and temperature ranges?
Operating pressure and temperature are key factors. Be sure to consider both working pressure and burst pressure. Similarly, identify continuous and peak temperatures. Most metal hoses are designed to work between -200°C to +800°C, but material and braid design play a major role in temperature tolerance.

c. What are the installation conditions?
Understand the environment in which the hose will be used. Is it indoor or outdoor? Will it be exposed to UV, saltwater, vibration, or mechanical abuse? Additionally, note whether the hose will be stationary or moving, and if there will be axial, lateral, or angular movement.

2. Know the Hose Construction
A metal pressure hose typically comprises two main components: a corrugated metal hose and an outer braid.

a. Corrugated Core
This is the flexible core made of thin-walled stainless steel, often in a helical or annular pattern. The design allows for flexibility while withstanding internal pressure. Helical hoses offer better flexibility, while annular ones provide improved strength and are preferred for dynamic applications.

b. Braid Layer
Braiding made of stainless steel wire is added over the hose to increase its pressure capacity and provide restraint against elongation. Single braid is suitable for moderate pressure, while double braid enhances strength for higher-pressure uses.

Some hoses may include multiple layers or external covers for added protection from abrasion, insulation, or contamination.

3. Choose the Right Material
Selecting the right material is essential for performance and longevity. The most commonly used materials are:

Stainless Steel 304: Economical, good corrosion resistance, suitable for general-purpose applications.

Stainless Steel 316/316L: Enhanced corrosion resistance, especially against chlorides and acidic environments. Ideal for chemical and marine applications.

Bronze or Monel: Used for highly specific corrosive or marine applications.

Inconel, Hastelloy, or Tantalum: Premium materials for extremely corrosive or high-temperature applications.

Always consult a material compatibility chart and cross-check with the conveyed fluid and environment.

Final Thoughts
Selecting the right metal pressure hose involves more than just picking a size or material from a catalog. It’s a strategic decision that influences safety, efficiency, and cost-effectiveness in your operations. By evaluating your needs holistically — from media and pressure requirements to environmental conditions and compliance standards — you can ensure long-lasting performance and minimal downtime.

When in doubt, consult with a hose specialist or manufacturer. They can help you design a custom solution tailored to your operation’s specific needs.

The right metal pressure hose is not just a component — it’s a critical part of your system’s integrity. Choose wisely, and it will serve you reliably for years to come.

Inconel, Hastelloy, or Tantalum: Premium materials for extremely corrosive or high-temperature applications.

Always consult a material compatibility chart and cross-check with the conveyed fluid and environment.

4. Determine Hose Size and Length
Selecting the correct hose diameter is crucial for flow efficiency and pressure management. A hose that is too narrow may lead to pressure drop, while an oversized one can be less flexible and cost-inefficient.

Use the STAMPED acronym for detailed sizing:

Size (ID/OD)

Temperature (operating conditions)

Application (movement, installation, space)

Media (fluid/gas type)

Pressure (working and burst)

Ends (fittings and connections)

Delivery (length and shipping considerations)

When determining hose length, allow for movement, elongation, and contraction. Avoid making hoses too tight or stretched, which can lead to premature failure.

5. Select the Right Fittings and Connections
The hose is only as strong as its weakest connection. Ensure that the fittings are compatible with your system and suitable for the pressure and temperature range. Common fitting types include:

Flanged (fixed or swivel)

Threaded (NPT, BSP)

Welded ends

Cam-lock or quick disconnects

Choose fittings made of materials compatible with the hose and the media. For high-pressure applications, fittings must be installed by trained personnel to prevent leakage or blowouts.

6. Consider Flexibility and Motion
Understanding the type of motion your hose will experience helps determine the ideal design and installation method:

Static: Fixed at both ends with no movement. Straight hoses can be used.

Flexing: Moderate movement in one direction. Choose hoses with higher flex fatigue resistance.

Dynamic (vibratory or cyclic motion): Requires hoses with superior durability and possibly extra support or guides.

Avoid torsional stress (twisting), as it can cause rapid wear and failure. Use swivel joints or flexible hose loops where necessary.

7. Safety and Compliance Standards
Ensure that the metal pressure hose complies with relevant standards and certifications such as:

ISO 10380 (international standards for metal hose assemblies)

ASME B31.3 or B31.1 (for pressure piping)

API standards (oil and gas applications)

FDA or 3A (for food-grade hoses)

Certifications ensure that the hose meets required performance and safety benchmarks, especially in regulated industries.

8. Don’t Overlook Accessories and Installation Aids
Additional components can enhance safety and performance:

External guards: For abrasion and wear protection

Internal liners: Reduce turbulence or friction in high-velocity media

Thermal insulation: For extremely hot or cold environments

Supports and restraints: Prevent sagging or excessive movement

Proper installation with the right accessories can extend the life of your metal pressure hose and reduce maintenance costs.

9. Maintenance and Inspection
Even the best hose requires periodic inspection. Look for signs of:

Fatigue cracks

Corrosion or pitting

Braid wear or fraying

Leaks at connections

Create a preventive maintenance schedule that includes visual inspections, pressure testing, and replacement timelines. In high-risk applications, consider using sensors to detect early hose failure.

Selecting the right metal pressure hose involves more than just picking a size or material from a catalog. It’s a strategic decision that influences safety, efficiency, and cost-effectiveness in your operations. By evaluating your needs holistically — from media and pressure requirements to environmental conditions and compliance standards — you can ensure long-lasting performance and minimal downtime.
