Process

Dual Helical Filament Winding:

Standard pipe manufacturing process in which the fiber glass roving is wetted with
resin and is wound on steel mandrel at precalculated winding angles. The dual helical winding pattern is responsible for providing the composite product with maximum mechanical durability.

Liner layer:

The inner-most layer mostly impregnated with
Vinyl Ester resin (90%) to provide maximum
chemical resistance. The resin used will decide
the extent of its chemical and temperature
resistance.

Structure:

The structural wall is generally 70% glass and
30% resin providing it the optimum mechanical
strength. The entire process is controlled via
software in which we determine the winding
angles as well as the number of layers to be
wound on to the product. More the winding
angle, greater the elasticity of the pipe.

Use of ovens help in fastening the curing
process and also makes sure the bonding
takes place well. Once the pipes are extracted,
they are calibrated at the ends if required
(flexible joint).
