Metal Hoses (Braided Corrugated Hose)
DEVEL Braided Corrugated Metal Hose is a high-performance flexible piping component designed for the most demanding industrial environments.
Each hose features a highly flexible stainless steel corrugated core tube, wrapped in a durable high-tensile wire mesh 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.
Engineering options range from standard utility service to critical high-pressure limits. The assembly eliminates structural piping misalignment, dampens heavy pump vibration, and handles extreme thermal shifts — serving industrial steam lines, gas manifolds, cryogenic piping systems, and water delivery loops.
Key Features at a Glance
- Highly Flexible Stainless Steel Corrugated Core
Formed from precision-rolled austenitic stainless steel grades (SS304, SS316L, SS321) into an annular corrugated profile that delivers exceptional multi-plane flexibility. The seam-welded corrugated core ensures 100% gas-tight integrity for safely transporting hazardous liquids and high-pressure gases. - Durable Wire Mesh Braid Exterior
The outer layer of tightly woven stainless steel wire braid provides maximum hoop strength to contain internal pressure while shielding the flexible core from external abrasion, impact damage, and over-bending. Single or double-layer braiding options available depending on pressure requirements up to 20 MPa. - Superior Vibration Dampening & Misalignment Correction
Expertly designed to absorb continuous system vibrations from pumps and compressors, compensate for heavy thermal expansion between rigid pipe sections, and seamlessly correct minor piping misalignments — even in extremely tight installation spaces. - Wide Temperature Range & Chemical Resistance
All-metal construction enables flawless performance across extreme thermal ranges from cryogenic liquid temperatures to elevated steam conditions. Naturally resistant to fire, deep moisture penetration, UV degradation, and most corrosive chemicals — delivering significantly longer service life than rubber or plastic alternatives. - Versatile End Connection Options
Highly configurable with fixed or swivel flanges, robust camlock couplings, seamless weld ends, or threaded unions (NPT/BSP) to integrate directly with existing machinery, valves, and pipeline infrastructure without requiring additional transition adapters. - 100% Gas-Tight Leak-Proof Integrity
Features a 100% gas-tight, hydroformed/seam-welded corrugated core construction that makes it safe and highly reliable for conveying critical gases, steam, and hazardous industrial fluids without risk of leakage under pressure cycling conditions.
Key Technical Advantages
- Exceptional Flexibility: Expertly designed to absorb continuous system vibrations, compensate for heavy thermal expansion and contraction cycles, and seamlessly correct piping misalignments in extremely confined spaces where rigid connections would fail.
- High Pressure & Temperature Resistance: The tight stainless steel braiding provides maximum hoop strength to withstand operating pressures up to 20 MPa, while the all-metal construction allows for flawless performance across critical thermal ranges from cryogenic to high-temperature service.
- 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 in harsh industrial environments.
- Leak-Proof Integrity: Features a 100% gas-tight, seam-welded corrugated core construction, making it the ideal choice for safely transporting hazardous industrial liquids, critical chemicals, and high-pressure gases without risk of leakage.

Installation Guidelines
- Avoid Torsion: During layout and final light-up, ensure the hose assembly is never twisted or subjected to torque, as rotational stress drastically accelerates fatigue and reduces service life.
- Proper Bending: Always strictly maintain the specific minimum bending radius outlined in the technical dimensions above to prevent structural kinking, convolution damage, and premature failure under pressure cycling.
- End Connections: Highly configurable with fixed or swivel flanges, robust camlock couplings, weld ends, or threaded unions to fit existing machinery and pipeline infrastructure without transition adapters.
Typical Applications
- Industrial Gas & Oil: Safe transfer of cryogenic liquids (such as LN2 and LOX), high-temperature steam, and high-pressure oils in petrochemical processing facilities and LNG terminals.
- Mechanical Equipment: Effective vibration isolation and noise reduction for heavy-duty pumps, air compressors, and industrial engines in manufacturing plants and power generation stations.
- Steel & Metallurgy: High-temperature blast furnace cooling lines, hydraulic press systems, and fluid lines operating under severe ambient heat in foundries and rolling mills.
- Food & Pharmaceutical: Clean-grade fluid transfer options configured with polished stainless steel surfaces to comply with strict sanitary processing criteria and GMP requirements.
- Chemical Processing: Flexible piping assemblies for aggressive media transport, chemical dosing lines, and solvent handling in specialty chemical production facilities.
- Marine & Offshore: Engine room fuel lines, ballast system connections, and exhaust compensators aboard commercial vessels and offshore platforms with DNV/BV classification compliance available.
