SUPERLIT Helical Filament Wound glass-reinforced thermosetting resin pipe offers superior corrosion resistance and a combination of high mechanical and physical properties which have been proved in most severe operating conditions all over the world.
Pipes are manufactured using the discontinuous filament winding process on computer-controlled machines by adjusting the relative speed of mandrel rotation with the controlled winding of the impregnated fibers on desire pattern, angle, and thicknesses over a rotating mold synchronous with glass distribution head movement.
The inside diameter of the finished pipe is defined by mandrel outside diameter and designed wall thickness is achieved by repeated winding passes and the outside diameter of the pipe is determined by the wall thickness. Following the completion of the curing, mold is separated from the cured pipe by using extraction equipment.
Helical Filament Winding Production Method
Fields covered by SUPERLIT Helical Filament Winding GRP products are the following :
A complete list of available nominal sizes and pressure classes of pipe and fittings produced by Helical Filament Winding is given in Table.1
The standard SN class of the pipes are SN:10 000 Pa. Higher stiffness classes are available up to SN 1.000.000 Pa for jacking applications or special project design conditions.
There are two types of jointing is available for pipe jointing systems. Available type and jointing system details are given in Table.1 :
1) Restrained Rigid Type: Butt-Wrap Lamination or Locked Type
2) Un-restrained Flexible Type : Full Face Coupling
SUPERLIT Helical Filament Winding products are certified according to ASTM 3517 and ASTM 3754 standards.
