AIM AND OBJECTIVES
As we know that when water from height are falling down in the pipe, it create sound which may disturb human beings .
Our main aim to reduce the sound which occurs during water flowing in the pipe.
Targeted remedies
By increasing the density of fillers.
By reducing coefficient of friction between inside wall of pipe and flowing water.
VISIT TO PIPE PLANT
Positive response from SAMRAT Pipe at Beed.They provide us raw material related to our recipe.
