The engineering that governs a metal hose or a bellows is not proprietary. Publishing it costs us nothing and saves you a phone call — and an assembly specified from real data lasts longer than one specified from a picture in a brochure.
Calculators
Specifying
How to Specify an Assembly
The seven inputs that turn an enquiry into a specified, priced assembly — and why each one matters.
View →Movement Types
Axial, lateral, angular, torsion and vibration. What a hose will take, and the one movement it will not.
View →Bend Radius & Live Length
Static versus dynamic radius, and the formulas for calculating the length a moving installation needs.
View →Limits and data
Temperature Derating
Working pressure falls as temperature rises. The factors, and how to apply them.
View →Media Compatibility
Which grades suit which media, the chloride problem, and where stainless simply will not do.
View →Flow Velocity & Pressure Drop
Velocity limits by medium, why corrugated bore resists flow, and when a liner becomes mandatory.
View →Material Grades
304L, 316L, 321, 904L and the nickel alloys — composition, cross-standard designations, and what each is for.
View →Practice
Installation Guide
The rules that decide whether an assembly reaches its design life, with the reason behind each.
View →Failure Modes
What each failure looks like, what caused it, and how to stop it happening again.
View →Testing & Inspection
What we test, to what acceptance criteria, and what documentation you receive.
View →Standards We Build To
ISO 10380, ISO 15465, EN 14917:2021, EJMA 11th Edition — what each governs.
