DESCRIPTIONS

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.

Applications

LANDYOUNG GRP jacking pipe is suitable for use in pressure, non-pressure and trenchless applications for potable, non-potable, industrial, drainage and wastewater systems.

● Water

● Sewage & wastewater

● Pipe-relining

● Road & rail culverts

● Asset encasement (e.g. protection for pressure pipelines)

● Ducts
