Product Description:Pipes & ducts Pipes & ducts are
manufactured using the "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
with different angles can be wound. In order to increase the pipe
stiffness, especially on large diameter pipes, silica sand can be added
to parallel layers of wall. Nominal diameter Nominal size of pipe and fitting is based on internal diameter. The range of available sizes is 20 to 4000 mm. Nominal
pressure classes: Pipes and fittings are classified according to
nominal pressure. Standard pressure classes are 4, 6, 10, 16, 20 and 25
bars. Intermediate or higher-pressure classes are considered on request
or depending on the design parameters and conditions Nominal lengths Pipes have a length of six meters up to ND150 and 12 meters for bigger diameters. Fittings A wide range of fittings as elbows, reducers, tees, caps, flanges etc. is available. Fittings
are manufactured by the hand lay-up, contact molding and spray-up
process. In hand lay-up and contact molding processes veil and alternate
layers of mat and woven roving saturated with resin are applied on the
mold. In spray-up process continuous strand roving is fed through a
chopper gun, combined with catalyzed resin, and sprayed onto the mould
surface Prefabrication spools Prefabricated spools save installation
time as well as costs, freeing the designer from being limited to
standard fittings and allowing junction sizes shapes to be specified and
manufactured as a better alternative to a complex series of joints.
