Product Details

Layflat Bore Hose , Flexible bore water rising main layflat hose 1 inch to 8 inch

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.

Structure

Inner tube and cover: Smooth PU cover and tube.
Reinforcement: Circular woven polyester jacket
Incorporates a strip of reinforced polyurethane on the side to support the electrical cables and accessories

Operating Temperature Range: From -60° F to 176° F(-50° C to 80° C)
Standard Color: Blue, other colors available per request
Couplings: Stainless steel couplings with BSP thread,etc.

Standard Length: 300ft/91.5m, 330ft/100m,660ft/200m; other lengths available per request

Raw Materials: PU made by BASF, NSF61 approved

Advantages

Installation

■ Assembly hoses with HPHC BSP coupling
■ Swivel HPHC BSP coupling onto submersible pumps
■ Attach power cable using Welline Cable Straps
■ Hang Welline hoses and pumps
■ Lower Welline hoses and pumps into well
■ Assembly the other end of hoses onto HPHC BSP coupling
■ Swivel top HPHC BSP coupling onto Well Head Base
■ Fix Well Head Base
■ Install elbows, valve and other output pipes

For some large boreholes, vehicles and cranes are required to assist installation.
