The fivefold longer life of Mammoth TPU extruded-through-the-weave lay flat hose compared to the life of nitrile rubber/PVC, has lead to Mammoth hoses quickly becoming one of the most cost effective investments for water transfer in the oil and gas industry. The manufacturing process for extruded-through-the-weave hose doesn’t involve the use of tubes or adhesives. Instead, in a unique one step procedure, thermoplastic polyurethane material (TPU) is fed into a heated extrusion channel or barrel. As the woven reinforcement jacket is drawn through the barrel, the TPU is extruded through the weave under carefully controlled conditions of temperature and pressure. The result is a hose with a homogeneous single wall of reinforced polyurethane; smooth, tough, resistant to abrasion and weathering, and ready for heavy duty service under the harshest conditions.
