uPVC Pipes

Polyvinyl-Chloride (PVC) is a plastic product which has matchless versatility. It effectively replaces wood, paper and metal in several applications. As such plastic pipes have been progressively replacing conventional pipes like G.I., Cast Iron, Asbestos Cement or Stone-ware for a number of important and uses. Among the various types of plastic pipes which are commonly used for such applications PVC pipes are the most widely used all over the world on account of their most favourable balance of properties. PVC pipes are light in weight, rates for use under pressure, easy to install, low on maintenance cost, and have low frictional losses. Rigid PVC pipes have wide variety of uses in fields like city/town/rural water supply scheme, spray irrigation, deep tube well schemes and land drainage schemes. PVC slotted and corrugated pipes are ideal systems for drainages of water from land where water logging is inevitable.

Raw Material

The main raw material required is compounded PVC resin. Other compounding materials like plasticizers, stabilizers, lubricants and fillers are also used in the manufacturing of uPVC Pipe.


The various process steps involved in the manufacture of rigid PVC pipes are as follows:
Blending, Extrusion, Sizing, Traction & Cutting

Blending:- Production begins with exacting blend formulations of the best compounds available, ensuring that we consistently achieve our desired physical properties. High quality Plastisizers, Satabilizers, Lubricants and Fillers are blend in a high speed machine to improve processibility and improve the endure stability, accoriding to the national and internation standards.

Extrusion:- The compound resin is fed to the twin screw extruders where the inserts and die body for the required pipe diameter are fitted. The PVC compounds are then passed through a heated chamber and they get melted under the compression of the screw and temperature of the barrel. The marking on the pipe is done at the time of extrusion. Twin screw extruder have a wide-ranging capability of standard 1″ to 12″ diameters and custom extrusions for the production of pipe. Constant supervision and regular quality testing ensure consistent quality throughout each production run.

Sizing:- The pipes coming out from the extruder is cooled in the sizing operation. There are basically two types of sizing used for manufacturing of pipes. They are (i) Pressure sizing & (ii) Vacuum sizing.

Traction:- The next operation needed after sizing is traction. The tube traction unit is required for continuous haulage of the pipes being extruded by the extruder.

Cutting:- The last operation needed is cutting. There are basically two cutting techniques for rigid PVC pipes i.e. manual and automatic. The pipes are now ready for dispatching.
