Pre insulated PE Piping system

Pre Insulated piping is best Chilled water pipe in India 2020

George Fischer make Pre Insulated PE 100 Armaflex Class 0 Insulation with Electro fusion jointing Piping system

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.

General Information

PE Pre – Insulated is a complete plastic pipe system for secondary and refrigeration systems operated with brine or water diluted glycol. The system is based on proven and cold-shock resistant ABS pipes and fittings.

PE Pre Insulated is ideal for use cold storage, in food and beverage productions ( e.g. breweries,dairies,slaughter-houses), in supermarket as well as for process cooling in industrial cooling water systems or in data centers.

Working Temperature range:

Ø -40° C ( +40° F) to + 60°C ( 140°F) PE

Application Areas :

Ø Dairies

Ø Slaughter houses

Ø Meat Processing

Ø Industrial cooling water

Ø Breweries

Ø Food production

Ø Fish industry

Ø Air conditioning

Systems Advantages : Your benefit Speed

Pipes are delivered direct to the site ready to install. Simple insulation technique using speedily Electrofusion with no need to remove the PUR using internal diameter jointing fittings. Time and cost saving handling due to the low weight of plastics.

Zero corrosion :

NO maintenance , reducing downtime , constant long – term efficiency.

Reduse costs for your hanging system:

Simplified pipe supports on outer jacket no need for special refrigeration pipe hangers. Pre insulated pipe required 30% less hangers than standerd plastic pipe.Lower weigh compare to metals means lower structural cost.

Top efficiency :

Save energy , thermal conductivity 0.026w/m K .PUR density ≥55kg/m³ with standers thickness of 35mm for excellent insulating properties. Smooth pipes, no encrustation, low pressure drops,no energy bridges due to support on outer jacket.

Reliability :

Quality : GF piping systems products are the nomber 1 Plastics Industrial Piping system manufacturer in the world. Tried and tested jointing with electrofusion technique.

Innovative and clever:

Developed for your needs. Internal pipe connections mean no need to remove the PUR insulation from the pipe or fittings.

Hygienic and aesthetic :

Full technical support during installation:

On-Site advice and jointing technique training will be provided.

Training video for elecrofusion jointing is also available on U-Tube

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.
