Engineered for Extreme Pressure Performance
High-pressure applications demand hose assemblies that can tolerate substantial internal loads while maintaining durability and integrity. Flexmetallic’s corrugated metal hoses are reinforced with tightly woven stainless steel braids, providing exceptional pressure containment and protection against mechanical stress.
Each assembly is carefully designed to accommodate specific operating pressures, vibration levels, and movement patterns, ensuring long service life and consistent performance. Typical applications include hydraulic systems, chemical process transfer, gas manifolds, and pressurised steam systems where precision and reliability are critical.
Double Braiding for Strength and Stability
Double-braided designs enhance the capability of high-pressure hoses by adding a secondary sheath of stainless steel wires around the primary braid. This construction increases operating pressure capacity, minimises elongation under load, and prevents external abrasion.
The inner corrugations allow flexibility for movement and vibration absorption, while the outer double braiding provides reinforcement and resistance to mechanical damage. This synergy between flexibility and strength ensures a secure, stable connection in installations that experience pressure surges or dynamic movement.
In environments subject to pulsation or sustained high pressure, double-braided hoses deliver optimal reliability. Flexmetallic’s experts can advise on the ideal braid configuration and wall thickness to meet the specific safety factors of each system.
Material Selection and Corrosion Resistance
Flexmetallic’s high-pressure hoses are available in a variety of stainless steel grades to suit different fluid media and corrosive conditions. Common choices include 304, 316, and 321 stainless steel, which offer excellent resistance to oxidation and stress cracking. For specialist requirements, alternative alloys can be supplied to ensure full compatibility with the application environment.
Proper material selection extends service life, maintains mechanical strength, and reduces maintenance frequency, supporting optimum operational efficiency in critical industries such as petrochemicals, power generation, and offshore systems.
Safety and Regulatory Compliance
Safety lies at the core of every Flexmetallic hose assembly. Each unit is manufactured and pressure-tested in accordance with recognised international standards. This includes hydrostatic and pneumatic testing to verify performance under both operating and surge conditions.
All hoses undergo dimensional checks, visual inspections, and weld integrity testing. For pressure-critical projects, test certificates and material traceability documentation can be provided to meet client and regulatory requirements.
Key safety features include:
- High burst pressure margins and fatigue resistance
- Secure end connections with welded or mechanically attached fittings
- Stainless steel construction offering fire and corrosion resistance
- Design compliance with BS 6501, ISO 10380, and related quality standards
These features ensure that Flexmetallic hoses deliver dependable containment and performance, even under extreme conditions.
Designed for Versatility and Integration
High-pressure metal hose assemblies can be configured with a wide selection of fittings and terminations, allowing seamless integration into new or existing systems. Standard end fittings include flanges, threaded connections, and quick couplings, available in multiple pressure ratings.
Their flexibility makes them particularly well-suited for applications where rigid metal pipework cannot accommodate thermal movement, vibration, or misalignment. By absorbing stress and motion, these hoses help prevent fatigue and damage to adjoining components.

Testing, Quality Assurance, and Certification
Each Flexmetallic hose assembly is manufactured under tightly controlled conditions. During production, welds are performed using approved techniques and inspected for conformity. Following assembly, hoses undergo 100% pressure testing to validate their performance and leak integrity.
Testing processes can include:
- Pneumatic leak test as per ISO10380
- Hydrostatic pressure testing up to and beyond working limits
- Helium and nitrogen leak testing for gas service
- Life cycle and vibration testing for fatigue resistance
- Visual and dimensional checks for consistency and finish quality
Quality assurance is maintained through ISO-certified manufacturing systems, ensuring that every hose leaving the production line meets Flexmetallic’s exacting standards for safety and durability.
