ACKNOWLADGEMENT In the course of preparing for this seminar I have

indebted my self to many individuals first of all I am greatful to the cami album makers of cipet for giving us the opportunity of explaining over selves on various topics .I want to express my gratitude to Mr. Sanjay Saxena Sir and Mr. Mukesh Sir far this valuable guidance and previous time which they happily give to me regarding preparation of this seminar

I am also grateful to Mr. Kirti Sir ,Mr. Vijay Patel Sir as the topic directly to CPVC Pipe application & advantage.I am also grateful to testing staff for their suggestion .Also I am very much grateful to library staff for providing me books

Finally, I would like to thank by my friends for their supports

INTRODUCTION “Harvey Wismer”, founder of Harvel plastics

(Now George Fisher Harvel L.L.C) Helped develop the nations first CPVC pipe more than 55 year ago.

As a leading plastic pipe manufactured . Harvel broad experience with CPVC pipe instrumental to the successful introduction of “Blaze Master” CPVC pipe to the fire sprinkler industry .

In fact more than 25 years ago .Harvel was first in the plastics industry to develop and manufacture specialty plastics for five splinkler application

In the mid 1980.s the “Temp Rite” division of “B.F

Goodrich” company invented and introduced “Blaze

Master” CPVC compound to a select group of pipe & fitting

manufactures to help develop and manufacture

CPVC piping products for the fire sprinkler industry.

Chlorinated PVC is thermoplastics pipe material

nationally accepted since 1982 CPVC has many benfits when compared with other

plumbing material ..It is primarily used for supplying hot and cold

portable water and industrial liquid application.

Origins CPVC was first produced commercially

in the mid 1930 in Germany by chlorination of PVC polymer in solution in a chlorinated hydrogen (ISO 1043-1978)

However its logical consistency with accepted letter symbols for other polymer is questionable

CPVC Pipe Extrusion

CPVC Pipe processing is done

on Twin Screw pipe Extrusion

Plant , where the specially designed screws are triple chrome plated for

longer life

Property- Two more important points of differnce between .PVC polymer and

CPVC are latters higher melts viscosity in processing and

high glass transition temperature vicat softening point and HDT under load. Like density of CPVC pipe

increase with increase chlorination content

Use of Twin Screw Extruder

EACH SCREW REQUIRES SPECIAL SCREW GEOMETRY TO PROCESS FOR OPTIMUM SHEAR, AS THE MATERIAL IS MUCH MORE HEAT SENSITIVE AS COMPARED TO NORMAL PVCThe screws are designed to give good melt homogeneity.

The Die Head manufactured from stainless steel offers least resistance and stagnancy to flow path

THE FLOW OPTIMIZED SPIDER DIE OFFERS UNIFORM MELT DISTRUBUTION AND VERY GOOD FLOW PROPERTIES THROUGHOUT THE ENTIRE FLOW CHANNEL

It also allows optimum dwell time spectrum with targeted temperature guidance of sensitive material to give outstanding pipe quality

IT ALSO ENSURES BENEFITS LIKE LOW PRESSURE BUILT UP , LOW MELT TEMPERATURE , EVEN WITH HIGH THROUGHPUT CPVC being highly viscous requires high torque gear box and drive.

Properties of CPVC pipe Chemical resistance Heat resistance Mechanical properties Fire properties

Wide Range of application The excellent

quality of CPVC Pipes make them ideal for

Carrying drinking water and food liquid

water and waste treatement systems

Hot and cold water distrubution in residential, industrial and public project

The boom in the building and construction industry, especially in the housing and commercial building sector has fueled high demand for cost effective, reliable, quality piping and plumbing systems. The choice of piping systems for water utilities is based on overall long term value. They must deliver on factors like long term costs, reliability, versatility, environmental effect, drinking water safety and public health. CPVC Piping systems are the ideal choice, because they are corrosion resistant, durable, smooth, friction free, resistant to bacterial growth and environment friendly, besides a host of other user friendly features.

Fields of application Hot and Cold water distribution in residential, commercial and public projects, high and low rise buildings, corporate houses and academic institutes, solar heater application etc.

Different type of CPVC Pipe

Pipe for electric net improvement (Large dia CPVC Pipe)

Solar heating , central heating and radiant floor heating application . Installation and Maintenance of CPVC PIPE

Advantage of CPVC Pipe The must deliver on factor like long term costs

reliability versatility environmental effect drinking water safety and public.

High flexibility. These pipe system are tough rigid and strong

with higher pressure bearing capacity. No effect of electric / heat source. Installation is by fast cold welding. Asthetic , extremely easy , cost effect to

handle install. Excellent performance in tough conditions.

The family handyman CPVC tubing is ideal

for water supply line. It is easy to cut

assemble using compressing of cemented fitting

Its durable too Harse water won't harm the material ,unlike copper which will erode from acidic water.

CPVC Tubing cutter Cut the CPVC

tubing straight and square with the special tool designed for this purpose.

The cut will be burr free and ready for cement or for mechanical fitting.

Are there any drawback to CPVC Pipe

You may have heard claim about CPVC and chemical leading the transfer of chemical from the pipe into the water.

Bawere that many home copper or steel water pipe system are used as grounding for electrical wiring CPVC

Use in Home supply water CPVC is code

complaint almost everywhere this well designed water supply system has been used in more than million home date

IT is capable of carrying 180degree water at 100psi (water in average home is about is 125 degree at 50 psi

Cement joint solutions Spread cement

second wear special solvent proof gloves for extensive work too much exposure can be hazadous.

Follow the identical precedure including applying dish washing liquid to end.
