Well Riser PU Layflat Hoses for Extracting Underground Water Heavy Duty Through the Weave
Welline HP is made from extruded thermoplastic polyether based polyurethane (TPU) with excellent wear & tear properties and is approved by NSF 61 standard. The reinforcement is made from circular woven filament polyester yarn. The extrusion through the weave production method gives a very strong bonding between cover and lining as well as firmly encapsulating the woven polyester. The structure of Welline HP ensure that exposure to seawater and contamination by most chemical substances, hydrocarbons, oils, alkalis, acids and greases must have no effect on the short or long term performance of Welline HP hose.
