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
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
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 email@example.com 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.
