FRP Jacking Pipe

FRP Jacking Pipe is manufactured using the discontinuous dual helix filament winding process on computer controlled machines. By adjusting the relative speed of mandrel rotation and glass distribution head movement, helical reinforced layers can be wound with different angles. The angle with the axis of the pipe can vary between 45deg; And 88deg; . The inside diameter of the finished pipe is defined by the mandrel outside diameter and the designed wall thickness is achieved by repeated winding passes. In such a way the outside diameter of pipe (OD) is determined by the pipe wall thickness. In order to increase the pipe stiffness, especially on large diameter pipes, silica sand can be added to parallel layers of the mechanical wall.
FRP Jacking Pipe
Main characteristics of this process are the following:
The Bell and Spigot joint is an integral part of the pipe.
The cross winding allows enough flexibility in the design to specify pipe of any axial and hoop strength.
The axial strength is normally higher than that of pipes produced with other processes.
Pipe stiffness is not related to joint stiffness which in any case is higher than the pipe stiffness and guarantees a very stable joint practically without deformation.

The pipe could be made with our without silica sand depending on the load conditions.
