Product Overview
The Braided Corrugated Metal Hose from DevelFluid is a high-performance flexible piping component designed for the most demanding industrial environments. It features a precision-formed corrugated inner tube for superior flexibility and a high-tensile stainless steel wire braid exterior. This premium engineering combination allows the hose to handle high internal pressures while providing excellent protection against external mechanical damage and preventing axial elongation under stress.
Technical Advantages
- Exceptional Flexibility: Expertly designed to absorb continuous system vibrations, compensate for heavy thermal expansion, and seamlessly correct piping misalignments in extremely tight spaces.
- High Pressure & Temp Resistance: The tight stainless steel braiding provides maximum hoop strength to withstand high operating pressures, while the all-metal construction allows for flawless performance across critical thermal ranges.
- Superior Durability: Naturally resistant to fire, deep moisture penetration, and most corrosive chemicals, ensuring a significantly longer service life compared to standard rubber or plastic hose alternatives.
- Leak-Proof Integrity: Features a 100% gas-tight, seam-welded corrugated core, making it the ideal choice for safely transporting hazardous industrial liquids, critical chemicals, and high-pressure gases.
Applications
- Industrial Gas & Oil: Safe transfer of cryogenic liquids (such as LN2 and LOX), high-temperature steam, and high-pressure oils.
- Mechanical Equipment: Effective vibration isolation and noise reduction for heavy-duty pumps, air compressors, and industrial engines.
- Steel & Metallurgy: High-temperature blast furnace cooling lines, hydraulic systems, and fluid lines under high ambient heat.
- Food & Pharma: Clean-grade fluid transfer options configured to comply with strict sanitary processing criteria.
Installation Guidelines
- Avoid Torsion: During layout and final tight-up, ensure the hose assembly is never twisted or subjected to torque, as rotational stress drastically accelerates fatigue.
- Proper Bending: Always strictly maintain the specific minimum bending radius outlined in our technical dimensions below to prevent structural kinking and premature failure.
- End Connections: Highly configurable with fixed or swivel flanges, robust camlock couplings, weld ends, or threaded unions to fit existing machinery.
