2. 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 pipe.
By reducing coefficient of friction between inside wall of
pipe and flowing water.

3. Pipe Extrusion

8. TROUBLESHOOTING WE FACED…….
PROBLEM CAUSES REMEDIES
1. Material was not
melt properly
1. Low temperature
of barrel and die
1. Increased barrel
and die temp.
2. Breaking of pipe 1. Low melt strength. 1. Reduced screw
rpm.
2. Reduced speed of
catterpillar
3. Flow lines 1. Poor mixing 1. Use correct screw
design
