Continuous Filament Winding Process GRP Jacking Pipe for Waste Water Treatment

Basic Info.

Product Description

Product Description

LANDYOUNG GRP jacking pipes is manufactured in accordance with international standard using Helical FILAMENT winding process and Continuous FILAMENT winding process on computer controlled machines.

GRP jacking pipe is designed to meet the exacting demands of pipeline construction and rehabilitation using trenchless micro-tunnelling and pipe-relining methods.Helical FILAMENT winding process (Bell and spigot joints)GRP Pipe is manufactured using the helical (reciprocal) filament winding process by which impregnated glass fiber reinforcement with resin are applied onto a precision steel mandrel in a prescribed pattern. Repeated application of wetted fibers results in a multi-layered structural wall construction of the required thickness.Continuous FILAMENT winding process (Coupling joints)GRP Pipe is manufactured on a continuous filament winding machine. This machine consists of a mandrel composed of a helical wound continuous steel band, supported by beams forming a cylindrical shape. As the formed mandrel turns creating a multi-layered structural wall of the required thickness.

Production Process
