Frequently Asked Questions
What is the maximum working pressure for a 1-inch hose?
Based on the specifications, the 1-inch (DN 25) hose has a maximum working pressure (MAX W.P.) of 17 BAR (247 PSI).
What is the minimum bend radius for the DN 51 (2") hose?
The minimum bend radius (MIN B.R.) for the DN 51 (2") hose is 300 mm.
How does the working pressure change as the hose diameter increases?
As the hose inner diameter (I.D.) increases, the maximum working pressure generally decreases. For example, a 3/4" hose supports up to 21 BAR, whereas a 4" hose supports up to 2 BAR.
What is the safety factor ratio between burst pressure and working pressure?
The safety ratio between the minimum burst pressure (MIN B.P.) and maximum working pressure (MAX W.P.) is 4:1. For instance, the 3/4" hose has a working pressure of 21 BAR and a burst pressure of 84 BAR.
What are the outer diameter dimensions for the DN 19 (3/4") hose?
The outer diameter (O.D.) for the DN 19 (3/4") hose is 32.0 mm, which is equivalent to 1.26 inches.
What is the minimum burst pressure of the 4" hose in PSI?
The minimum burst pressure (MIN B.P.) for the 4-inch (DN 102) hose is 116 PSI (8 BAR).
