Why Lay-Flat Hose?
In many fluid transfer applications involving a high volume of fluid or water, the use of layflat hose can overcome various limitations which rigid pipe is unable to. These include the ability to deploy and retrieve quickly, compact storage and transport, the flexibility in laying out, to name but a few. In contrast, the use of rigid pipes is cumbersome and costly and therefore requires a lot more joints, welding, machinery and manpower to install to suit the changing topography. The benefits of layflat hose not only bring significant cost-savings but health, safety and time benefits as well.
Flexible layflat hoses offer many advantages over rigid, inflexible types of hoses such PVC, poly, steel or fibreglass pipes. This includes:
- Quick deployment and retrieval
- Storage volumes
- Handling and usage
- Transportation and transport costs
- Long service life
- Hassle-free maintenance.
Types of layflat hose
There are broadly speaking two types of layflat hose:
- The vast majority are those with braided or spun reinforcement, like hydraulic and garden hoses. The amount of reinforcement determines the burst pressure. This is why people equate thickness of hose wall with strength. Tensile strength or end pull is limited, and when such a hose is pulled hard, the braiding will cut into the stretched hose, and the hose delaminates.
- The second type of hose – which is the type manufactured by Crusader Hose – is made with woven reinforcement using high-tenacity polyester. This forms a hose with a reinforcement similar to a lifting sling. Since our reinforcement is woven, it interlocks and thus achieves a very high burst pressure and tensile strength (end pull) ratings. Typically, an identical pressure rating for a hose with woven jacket requires only 20% of the wall thickness compared to a hose with braided reinforcement. This woven construction makes the range produced by Crusader Hose superior in pressure and tensile applications.
TPU (thermoplastic polyurethane) is then pushed through the woven jacket using thru-the-weave extrusion to give a tough integrated cover for exceptional strength and hydraulic efficiency.
