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

3. VISIT TO PIPE PLANT
Positive response from SAMRAT Pipe at Beed.
They provide us raw material related to our recipe.

11. 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

12. PROBLEM CAUSES REMEDIES
4. Poor output 1. Improper screw
design.
2. Jamming of
screen pack
1. Ensure screw
design
2. Change screen
pack
5. Varing wall thickness 1. Mis-adjusted die
bushing
1. Adjust die bushing
