Process pipe


A wide range of pipe sizes and features are provided to meet many different application requirements. Diameters range is from 25mm (1 ") to 15,000mm (600 "). Standard lengths are 6m and 12m, but can be customized on request.

Fabrication of piping is the process of continuous glass filament winding on a computer controlled machine. Structural layer can be helical wound in different angle by adjusting the relative rotation speed of mandrel and the motion fiberglass distributor head. The included Angle of the pipe axis can vary from 45° to 88°.

The inner diameter of the finished pipe is determined by the outer diameter of the mandrel, and the design wall thickness is determined by the number of winding paths. In this way, the pipe wall thickness determines the outer diameter of the pipe. Silica sand can be added to the parallel layers of the structural layer to improve the stiffness of the pipes, especially on large diameter pipes.

The main features of this process are as follows:

A joint is an integral part of a pipeline.

Cross-winding allows sufficient flexibility in the design to specify any axial and hoop strength of the pipe.

The axial strength is usually higher than that of other processes.

The stiffness of the pipe has no relationship with the stiffness of the joint. In any case, the stiffness of the joint is higher than that of the pipe, which ensures the actual stability of the joint without deformation.

Connection forms include socket & spigot connection, field butt joint and threaded connection.

It can transport all kinds of liquid and gas medium, including water, hydrochloric acid, brine, ammonia and other corrosive liquid and gas, please contact for detailed data, it can meet the high and low temperature environment conditions of high altitude, land, sea and so on.

Nominal pressure class

Piping and fittings are classified according to nominal pressure. The standard pressure class is: 4,6,10,16,20 bar. Depending on the design parameters and conditions, medium or higher-pressure levels can be provided.

Pipe stiffness class

The pipes are classified according to different pipe rigidity. Standard stiffness classes are: 1250,2500,5000 and 10000 Pa. Medium or higher stiffness classes are available upon request or according to design conditions.
