Flexible Rising Pipe for extracting underground waterThrough-the-weave PU layflat hoses

Manufactured under ISO 9001 Quality Management Systems accreditation

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 acidThe borehole size is bigger than 3 inches.Maintenance cost is highEnd-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 strenth due to encapsulated reinformcement jacket. It means that it is the easiest to install submersible pumps with Welline hoses than any other types 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’s money! save users’ time!

Welline hoses, save lives!

Welline is one type of through-the-weave polyurethane (PU) covered hoses which are made of PU materials approved according to NSF 61 standard. Welline hoses shall be made from 100% high tenacity virgin synthetic yarn 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 adhesives of any type.The structure of Welline 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 hose.

Inner tube and cover: Smooth PU cover and tubeReinforcement: Circular woven polyester jacketIncorporates a strip of reinforced polyurethane on the side to support the electrical cables and accessoriesOperating Temperature Range: From -60° F to 176° F (-50° C to 80° C)Standard Color: Blue, other colors available per requestStandard Length: 330ft/100m, 660ft/200m; other lengths available per request;Comparable Brand: Wellmaster hose from Angus, Wellman hose from Mandals, Boreline from Crusader, Oroflex Well from TipsaRaw Materials: PU made by BASF, NSF61 approved
