Hydraulic Fluid Power Hose Assembly Inner Diameter Selection Flow Velocity Reference Chart

Hydraulic Hose Inner Diameter Selection Flow Velocity Reference Chart

Product Introduction

This is a professional hydraulic hose inner diameter selection nomogram (flow-velocity sizing chart) from DME&JDE, designed to help engineers, purchasers and maintenance personnel quickly and accurately select the correct inner diameter of hydraulic hoses.
By connecting the flow rate (L/min/gal/min) on the left scale and the fluid velocity (m/s/ft/s) on the right scale, the intersection of the straight line with the middle hose I.D. scale directly gives the optimal inner diameter. It clearly defines the maximum recommended velocity limits for pressure lines, return lines and high-pressure lines, ensuring that the hydraulic system operates efficiently, avoids pressure loss, cavitation and hose damage, and is suitable for all types of hydraulic system design, maintenance and hose replacement scenarios.

Product Advantages

Quick & Accurate Sizing: No complex calculations required, just connect two points on the scale to get the optimal hose inner diameter in seconds, improving work efficiency.
Clear Velocity Standards: Clearly marks the maximum recommended velocity limits for pressure lines, return lines and high-pressure lines, avoiding system failures caused by improper velocity.
Dual Unit Compatibility: Supports both metric (L/min, m/s, mm) and imperial (gal/min, ft/s, Dash) units, meeting the needs of global customers.
Professional Hydraulic System Design: Tailored for hydraulic oil, effectively prevents pressure loss, cavitation, overheating and hose damage, extending the service life of the system.
Easy to Use & Understand: Intuitive nomogram design, easy to master for engineers, purchasers and on-site maintenance personnel, reducing selection errors.
