Abstracts: The basic material which on Polymerization produces P.V.C. Pipes is Polyvinyl chloride which is in resin form is hard and rigid. The rigidity can be controlled by controlling the percentage of plasticizer at the time of compounding. Production of Rigid PVC pipe is based on plasticizing and homogenizing PVC compound and then passing the compound through an extruder. The hot molten PVC compound is extruded through a circular slit. Circular slit governs the size of pipe to be extruded. Different dies are used for manufacturing different size of pipes. Studying on pipe manufacturing process we identified the problem of bending of pipes when it is coming out from die, quality of pipe is low due to less hardness & ineffective cooling of pipe. To solve out the problem we are going to design the seizer which is fitted in front of die to reduce bending and adding a material to improve quality of pipe.
