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

Advantages

Minimum 50 years service life
LANDYOUNG GRP pipes are manufactured with corrosion resistant non-metallic raw materials. Since corrosion is not a problem, cathodic protection and extra insulation against corrosion are not needed. Thus, operational expenses and difficulties do not exist.
Light weight
Weight of GRP pipe:1/4 of steel pipes; 1/10 of concrete pipes
Can be transported as nested, providing great savings
Quick and easy installation, no need for heavy and expensive equipment
Excellent hydraulic properties
Hazen Williams flow coefficient is 150(c=150). Due to the low friction losses, less pumping energy is required. Compared to steel and concrete pipes, same flow rates can be ensured using smaller diameters.
No lime or deposit formation inside.
Unlimited service area-application in every environment
Can be installed underground, aboveground, and also underwater.
Bell and spigot joints and coupling joints ensure total leak-tightness.
Flexible: successful experience in earthquake regions.
Can be installed inside old lines for relining.
LANDYOUNG GRP pipes are environmentally friendly.
