Construction

Inner tube: Thermoplastic polyether polyurethane extruded through the weave in a unique one step production process
Reinforcement: Textile. High tenacity polyester yarn, circular woven. Special weaving design for ultra-high tensile strength, minimum bending radius and low elongation under pressure. Totally embedded in the PU compound, excellent protected against mechanical damage
Cover: Thermoplastic polyether polyurethane extruded through the weave in a unique one step production process

Application and limits

Application: Heavy duty polyurethane layflat hose for demanding drainage and dewatering.
Features: Superior abrasion resistance, extremely hardwearing and durable for long service life, ultra-high tensile strength, resistance to oil, fuel and a wide range of chemicals (see resistance table in technical appendix), resistance to weathering, UV and ozone, lightweight and easy to handle compared to material handling hose in rubber, excellent cold flexibility, single lengths longer than 200 m (660 ft), 52 - 90 mm (2 - 3 1/2″) up to 500 m (1,650 ft), 102 - 127 mm (4 - 5″) up to 400 m (1,320 ft)
Limits: Operating temperature from −50 to +75 °C.
Working pressure depends on the inner diameter — see the table. Burst pressure is a reference value, not a working pressure.
Layflat hoses are not suitable for suction.
Technical data based on water.
For air pressure the minimum safety ratio is 1:4.
Depending on the application our product can be operated with a maximum working pressure up to 50 % of the bursting pressure.
Please consult us for approval.
To obtain maximum lifetime the end pull under working conditions should not exceed 1/3 of the breaking strength.
Other lengths on request.
