GRP pipe & FRP pipe & Fittings

The range of pipes dimensions and characteristics offered is wide and able to meet many different application's requirements. They can be produced in any diameter from 25 mm (2") to 3000 mm (120"). Standard lengths are 6 and 12 meters however customized lengths are available on request. 

Pipes are 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 45° and 88°. 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.

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

Nominal Pressure Classes
Pipes and fittings are classified according to nominal pressure. Standard pressure classes are: 4, 6, 10, 16, 20 bars. Intermediate or higher-pressure classes can be provided depending on the design parameters and conditions.

Pipe Stiffness Classes
Pipes are also classified according to specific pipe stiffness. Standard stiffness classes are: 1250, 2500, 5000 and 10000 Pa. Intermediate or higher stiffness classes are available on request or depending on the design conditions. 

Remark: Special sizes we can produce as your requests.

HDPE steel strip reinforced corrugated pipe  Features

n         High pressure bearing capacity, high impact resistance capacity: pipe is steel strip reinforced, high ring stiffness , good adaptability for any foundation conditions;

n         Economy: lower cost than the specifications of other Plastic Pipe, light weight, save transportation and construction costs, easy management and maintenance; large diameter, high ring stiffness;

n         Chemical resistance: will not be corroded by sewage, waste water and chemicals, will not be corroded by the substances in soil, it will not be damaged by plant roots;

n         Anti-aging: the pipe is generally in black color, can withstand the direct sunlight in the stacking  and  construction  process.

n         Excellent wear resistance, Better than steel pipe.cast iron pipe, cement pipe;

n         Superior drainage: small water flow resistant in the inner wall, Drain fast, Strong water passing ability. large fluid flow.

n         The composite of each layer is carried out in the molten state of the plastic, which is completely different from the winding pipe (medium hole wall tube), so the composite fastness of each layer is very reliable;

n         Pipe can be used hot melt welding, clamp type rigid connection, heat shrinkable belt connection and other connections, suitable for different piping system requirements, convenient and  reliable.
