hoses ng underground water Hoses + Fittings + Well Head + Elbow Welline, New Generation Flexible Rising Pipe for Extracting Underground Water When extracting underground water is necessary, Welline hoses are recommended strongly because of its innate advantage on rigid plastic pipes or steel pipes in the following situations: ■ Underground water is very deep.(For example, deeper than 60 meters) ■ Underground water is salty or acid ■ The borehole size is bigger than 3 inches. H Maintenance cost is high ■ End-users want to save money in long term Furthermore, Welline hoses are layflat, coilable, of long-length (its length can be more than 400 meters per piece), and can hold high pressure and strong tensile strength due to encapsulated reinformcement jacket. It means that it is the easiest to install submersible pumps with Welline hoses than any other type of rigid pipes because no extra connectors are needed and submersible pumps can be directly hung into the bottom of wells after pumps are connected to hoses with specicialized fitting beside the wells. In above scenarios, Welline hoses are your best option! Welline hoses, save users’ money! save users’ time! Welline hoses, save lives!

■ No joints between, pumps and well head ■ No corrosion ■ No bacteria growth ■ No money and time to waste on transporting, installing and maintaining rising main Welline and Welline HP are one type of through-the-weave polyurethane (PU) covered hose which is made of PU materials approved according to NSF 61 standard. Welline and Welline HP hoses shall be made from 100% high tenacity virgin synthetic yam circular woven and completely, totally embedded in the PU compound, excellent protected against mechanical damage, forming a single homogenous construction without the use of any glues or...
