2. ABSTRACT:
On June 26th, we had the opportunity to visit KAM Plastics Pvt. Ltd and meet
the owner of the company. During our visit, the owner provided us with a
detailed explanation of the manufacturing process and procedures employed in
the industry. Specifically, we learned about the production of drip irrigation
pipes. The company operates on a made-to-order basis, meaning that they
supply products based on the specific requirements of their customers.
WHY THIS INDUSTRY:
We chose drip irrigation pipe plant as it is a very beneficial and important
product. Even it’s manufacturing is a great method to understand and learn
from. Many farmers across the world use drip irrigation as to avoid water
wastage. It promotes saving of water and is cost effective to the farmers. Our
government also promotes drip irrigation and has asked farmers to use this
method. In this industry, we saw the manufacture of drip pipes and fitting of
drippers in the pipe.
MANUFACTURING PROCESS:
1. Material Preparation:
 Source and prepare high-quality polymers and plastic granules
along with master batch colour.
2. Extrusion:
 Add the granules and colour into mixer.
 Force the molten polymer through a die to shape the pipes.
3. Cooling and Sizing:
 Cool the pipes to solidify their shape. Drippers are added in the
pipe.
 Size the pipes to meet specific dimensions.
4. Marking and Printing:

3.  Mark or print necessary information on the pipes (e.g., logos,
specifications).
5. Quality Control and Testing:
 Conduct tests to ensure pipe integrity and functionality.
 Perform pressure testing, flow rate testing, and visual inspections.
6. Packaging and Shipping:
 Package the pipes for transportation and storage.
 Prepare for shipment to customers.
FLOW PROCESS CHART
We opted for the flow process chart for the study of this manufacturing
process because the material is the primary element in this industry. As the
material is being moved, and operated and all the activities are acted on it, the
flow process chart seemed the most suitable chart for the work-study.

7. CRITICAL EXAMINATION
Q1.What is major problem in drip irrigation?
ANS. Small tubing often becomes clogged from hard water and
although new designs include filters and self-flushing emitters, they
are costly. The tubing/system is unsightly. And because it's unsightly,
tubing is often covered by mulch or plant foliage, making it difficult to
monitor the effectiveness of the system.
Q2. What is Life of drip irrigation pipes?
ANS. Drip irrigation tubing is also known to degrade when exposed
to UV light. According to landscape professionals in the Albuquerque
area, you can expect the tubing to last for about ten years if it is
buried.
Q3. How much pressure required?
ANS. A minimum of 30 psi, although pressures can exceed 80 psi.
Q4. .What is the maximum length of drip irrigation line?
ANS. A standard outside hydrant has a maximum capacity of about 5
gpm, and can operate a maximum of 1000 feet of drip tubing with
0.30 gph emitters on a 12 inch emitter spacing (0.5 gpm per 100 feet
of tubing length), or about 300 1-gph point source emitters.
Q5. How strong is irrigation pipe?
ANS.200 pounds per square inch (PSI).
Q6. Why do irrigation pipes break?
ANS. When the temperature drops below freezing, water left inside
fire sprinkler and irrigations system pipes also start to freeze. As
water turns to ice, it expands, putting pressure on the sprinkler pipes
and irrigation lines, which can eventually lead to cracks, bursts and
other damage.

8. Q7. What type of metal is irrigation pipe?
ANS. Cast iron
Q8. Which pipe has more pressure?
ANS. The larger the diameter of the pipe, the lower the pressure.
Q9. What is the flow rate of a pipe?
ANS. The flow rate of a fluid passing through a pipe segment is the
volume of fluid per every second the fluid is travelling through the
cross-section of the pipe.
SUGGESTION FOR THE INDUSTRY
1. For cooling the pipes after being manufactured or during the
process, chilled water or coolants should be used in the vaccum
tanks.
2. The winder should be completely automated so that process is
not interrupted and the bundles or rolls of pipes are made
quickly.
3. To increase the life of irrigation pipes flush three times a season
when irrigating with clean water; with dirty water – after every
four irrigations.
4. To improve the system they should add new nozzles,replace
worn nozzles or change to closer spacing.
5. They should install an Antifreeze Loop to stop the pipe from
freezing and bursting.

9. CONCLUSION
Drip irrigation is the most efficient method of delivering water and
nutrients to crops. The flow process chart presented in this project
report provides a visual representation of the drip irrigation pipe
industry. By outlining the sequential steps involved and highlighting key
stages,the flow process chart enables process analysis,optimization and
enhanced efficiently. Thus by suggestions it might improve the possible
neccesities and in future with good investment the industry will get more
enhanced.
