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 25 to 3000 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.
Circular steel pipe is both openings and have hollow concentric sections of steel larger than the surrounding. The specifications of steel pipes are indicated by appearance dimensions and inner diameter and wall thickness, with a wide range of dimensions from very small diameter capillary to large round steel pipe of several meters in diameter. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry, and special uses. It can be divided into seamless, ERW, LSAW, SSAW steel pipe according to the production process.
We produce and sell steel pipes, carbon steel pipe, GI pipe, carbon steel pipe , SS pipes and Spiral steel pipe in long term.
