Corrugated Metal Hose Profile Stress & Fatigue Review
This engineering path collects the inputs required to evaluate corrugation stress and fatigue life for a specific metal hose construction.
Numerical calculator intentionally controlled: A defensible corrugated-profile stress or cycle-life calculation cannot be produced from nominal hose size, pressure, and temperature alone. It requires the exact corrugation geometry, wall thickness, pitch, convolution depth/radius, material properties at temperature, braid restraint, forming history, pressure-cycle range, motion amplitude, and a validated analysis method for the hose series. Until those controlled constants are loaded, the site will not publish a fabricated fatigue-life number.
Required Analysis Inputs
Hose Series & SizeExact manufacturer/product construction and actual ID/OD.
Corrugation GeometryPitch, convolution height/depth, crest/root radii, profile shape, and formed wall geometry.
Wall ThicknessNominal and minimum formed wall thickness, including tolerances.
Material PropertiesAlloy, modulus, yield/allowable stress, and fatigue basis at operating temperature.
Pressure CyclesMinimum/maximum pressure, cycle count, test pressure, and transient conditions.
Mechanical MotionAxial, lateral, angular, torsional constraints, bend radius, and cycle amplitude/frequency.
Braid RestraintSingle/double braid construction, braid angle, coverage, wire data, and end restraint.
End GeometryBraid collars, weld attachment, fittings, tangent lengths, and local stiffness changes.
Current Output
Use this page as a controlled handoff to engineering review. Once validated hose-series geometry and fatigue equations are loaded, this page can be upgraded to a numerical corrugation stress and cycle-life calculator without changing the public URL.
Submit Hose Profile Data for Review
A defensible stress or fatigue-life calculation for corrugated metal hose requires validated construction details, geometry, wall thickness, temperature-dependent material properties, pressure cycles, mechanical motion, braid restraint, end geometry, forming history, and an approved analysis method.
The page serves as a controlled handoff for engineering review until verified hose-series data and fatigue equations support numerical results.
