The pressure rating for large diameter PVC layflat hose will be affected by many factors
Material
The quality and property of the PVC directly determines its pressure rating. PVC with high tensile strength and burst resistance ensure the hose can work at high pressure.
Reinforce
Large diameter PVC layflat hose often includes a reinforce such as synthetic yarn or fabric. While it’s to enhance strength and pressure resistance. The type and density of the reinforce is good to the overall pressure rating of the hose.
Structure and design
The hose’s design, like wall thickness and size will affect the pressure. A thicker and sturdier structure can handle higher pressure.
Test
Supplier subjects large diameter PVC layflat hoses to various tests to determine their pressure rating. The hose is filled with water and then increase pressure until failure occurs. The pressure at which the hose fails make sure its pressure.
Standard
LDH hose PVC layflat hose must meet industry standards such as ISO. These standards ensures the hose meets certain performance criteria like pressure.
Each of hose has certain pressure range. Thus you should use it within the range. Otherwise it will crack or even burst. Then it will cause the work has to stop and cause economic loss.
