What is PVC layflat hose used for?

PVC layflat hose is primarily used for water discharge and delivery applications, including agricultural irrigation, sprinkler systems, construction-site drainage, mine dewatering, industrial water transfer, pump discharge and temporary water-supply systems. The appropriate hose construction and pressure rating should be selected according to the application.

How do I choose the right PVC layflat hose?

Consider the hose inside diameter, required working pressure, discharge flow rate, operating temperature, transferred liquid, hose length and working environment. For abrasive surfaces, frequent movement or higher-pressure applications, a heavier-wall or reinforced PVC layflat hose may be more suitable. working pressure : maximum 150PSI are available for diameter smaller than 6inch. maximum working pressure for 8inch is 90PSI. For 10inch, 12inch, 14inch, 16inch, their working presssure is 30PSI.

What sizes and working pressures are available for PVC layflat hose?

PVC layflat hoses are available in a range of inside diameters for applications from small irrigation lines to large-volume water discharge. Common sizes include 1 inch, 1½ inch, 2 inch, 2 1/2" inch, 3 inch, 4 inch, 5 inch, 6 inch , 8 inch, 10inch, 12inch, 14inch and 16inch. Working pressure depends on the hose diameter, wall thickness, reinforcement and product series. Always select the hose according to its rated working pressure rather than its burst pressure.

Can PVC layflat hose be used with a water pump?

Yes. PVC layflat hose is commonly used on the discharge side of water pumps. The hose diameter and working-pressure rating should match the pump outlet, expected flow rate and maximum discharge pressure. PVC layflat hose is generally not designed for pump suction because it may collapse under vacuum.

Can PVC layflat hose carry chemicals or liquid fertilizer?

Some PVC layflat hose constructions may be suitable for diluted liquid fertilizers and compatible agricultural chemicals. Compatibility depends on the chemical, concentration, temperature, exposure time and PVC formulation. Provide the chemical name, concentration and operating temperature before ordering so that material compatibility can be confirmed.

What fittings can be used with PVC layflat hose?

PVC layflat hose can be used with fittings such as camlock couplings, Bauer couplings, pin lug coupling, storz coupling, gost coupling, KC nipples or other suitable hose-tail connections, depending on the hose size and application. The fitting type and attachment method should be selected according to the required pressure, transferred medium and connection system.

What lengths, colors and customization options are available?

Common roll lengths include 20 m, 25 m, 30 m, 50 m and 100 m, depending on the hose specification. For 12-inch PVC layflat hose, both 30 m and 50 m lengths are available, while 14-inch and 16-inch hoses are manufactured in 30 m lengths only. Depending on the product specification and order quantity, SEAPEAK can also provide customized colors, wall thicknesses, pressure ratings, printing and hose assemblies. Please confirm the available options for your required specification.

What is the operating temperature of PVC layflat hose?

The permitted operating temperature depends on the specific hose construction and PVC formulation. Some SEAPEAK PVC layflat hose products are suitable for temperatures from approximately −10°C to +60°C. When the operating temperature exceeds 40°C, the hose's working pressure will decrease. Confirm the temperature and pressure requirements for the selected hose before use, particularly at elevated temperatures.
