Why +GF+ PE Pre –Insulation :

Commonly used in larger industrial refrigeration installations where large charges of refrigerant gases can be a health and safety issue, secondary refrigeration plants have several advantages:

Ø  Higher safety

Ø  Lower temperature stability and control

Ø  Lower maintenance costs

Ø  Environmentally friendly.

Seconder systems also allow remove of refrigerant gases from the working or retail area into a separate machine room. This means that Natural refrigerant gases such as ammonia or propane can be used to replace man-made Freon’s with danger to the personal or public. The result  is a 100% sustainably;e plant with zero impact on  the environment and with an improved efficiency. Chilled water

The Environment

The “Montreal Protocol” in 1987 set the first internationally agree timetable for the elimination of CFC gases .

The Kyoto Protocol followed in 1997 with the intention of further accelerating the reduction of green house gas emissions,including F- gases ( flurinated refrigerant).

The lats regulation in Europe is the EC Regulation No 842/2006. The ai of witch is to contain,prevent and thereby reduce emissions of fluorinated green- house  gases, as outlined in the Kyoto Protocol.

Efficiency is the key

The cold chain and environment climate control are integral parts of modern day life. We simply expect fresh food twelve months of the year and of course the fresher the better. Climate control whether in hospitals or for medicine are determining factors in the quality of our loves.The generation of cold for a whole range of application is part of the day –to –day life.

Refrigeration plants are major users of energy and pay a key role in environmental protection.In a supermarket,for ex – ample , 70% of the daily energy costs are attributed to the cooling and refrigeration plant. Cold stores and food production.

GF PE  Electro Fusion Jointing Technology

In the electro fusion process a heating wire permanently mouled into the fitting gets heated by current at a low voltage. The surrounding material around the wire gets melted and expands due to the warming. The melt starts closing the gap between pipe and fitting, leading to a heat transition to the pipe which also gets heated and melts in the welding zone. The pipe material also expands.

The increasing material expansion between pipe and fitting, which is hindered by the cold zones outside the welding zone, leads to a build up a welding pressure between pipe and fitting and a homogeneous welding connection emerges. 

GF Electrofusion Machines

The main difference between conventional heat fusion and electrofusion is the method by which the heat is applied. In conventional heat fusion (butt, saddle and socket) joining, a heating tool is used to heat the pipe and fitting surfaces. The electrofusion joint is heated internally, either by a conductor at the interface of the joint or by a conductive polymer. Heat is created as an electric current is applied to the conductive material in the fitting. PE pipe to pipe connections made using the electrofusion process require the use of electrofusion couplings. 

Jointing procedure of Pre Insulated pipes by Electrofusion

Step  1

By using rotary peeler remove top surface up to 0.20mm of PE pipe to get virgin polymer up to the insertion depth of Electrofusion.

Note :- Do not peel excise area then required

Step  2

By using PE Tangit  cleaner wipe the peeled surface area and wait for 2 minutes to dry up the surface of pipe which will moisture,dust,oil,grease on teh fusion zone.

Note :- Do not touched clean area.

Step  3

Connect the fittings on peeled surface and provide clamps to hold the fusion zone pipe and fittings to aoide movement  during fusion process.

Note :- Mark the insertion depth before starting fusion

Step  4

Connect the elecrofusion machine to fittings and start fusion process as per operating procedure and wait until fusion process complete.

Note :- Training is essential for Electrofuion process.

Gape Closer after Electrofusion Procedure on open fittings

It is recommended to do pressure test all joints before closing the gape between fittings and pipe to ensure no leakages  in piping.

Kindly wait at least one our from Elecrofusion joint to close the gape between two pipe ends and Fitting by Insulation.

Use standard insulation provided along with Electrofusion fittings for closing with no air gap in between the pipe and fittings.

Raw material POLYPROPYLENE and features:

Substances obtained from propylene by adding a naphtha obtained by polymerization of the molecules, i.e. larger molecules three flights of obtaining white colored material. In the production of 96% obtained from crude oil derivatives are used polipropilen directly related to the availability and price of world oil reserves and prices. I even have the right information we can give the world ; when the oil is finished, polypropylene, will end too. (PVC pipe raw material on the page made no comment on the subject.) Crude oil production is heavily due to the use of polypropylene raw material price is expensive at high pressure and temperature, which can be used safely for 50 years.
PPRC products subject to high temperature and high pressure high temperature continuously depends on the way it is not correct to keep. Due to the wrong application of this gives cause shortening of the service life of the pipe. Also 40°C. at higher values than it is to use drinking water pipes, which will be held constant. It does not fit in terms of Health. If these pipes are to be used at high temperatures, such as it is more reasonable to use this waste water or water heating. With the growing technology today, the raw materials used by 3 types of polypropylene plastic Pipe Plant. If we process them ;
