B) Electro Fusion Welding

Electro fusion welding is a method of joining PE pipes using fittings with integral heating elements Sockets are used to join mains and service pipes and saddle fittings are used to connect services to mains.

• The pipe to be joined must be prepared by removing the outer surface layer to a depth of around 0.2 mm, then pipe and fitting are clamped together to prevent movement

• Specified electric current is applied across the fitting terminals via a control box.

• The electric current passes through the embedded wire which heats the wire and melts the polymer, fusing the fitting to the pipe. The joint is allowed to cool before removing the restraining clamps.

Electrofusion fittings are available in Ø 20 to 355 mm, 7/12.5/16 Bar-Yellow, Blue & Black 2. Compression Joint

Jains have a range of compression fittings which could adapt to PLAIN ENDS of PE PIPES. Jains manufacture Compression Fittings suitable for PE pipes ranging from 20 mm to 110 mm OD with (10 &16 bar).

3. Flanged Joint

If transition is to be made to another piping material or if a pipe section capable of disassembly is required, then Jain PE Pipe Ends (also called Stub-Ends) are available that can be welded to the pipe by means of heat fusion. A metal backup flange with appropriately sized and spaced bolt holes permits bolting to standard or specially sized flanges. Jain PE pipes of desired lengths

can be supplied with the factory welded stub end and flange (of desired material) ready to be bolted together at the project work site.

• Inspect flange faces and ensure that they are clean and undamaged. • Check that the correct backing flange is supplied.

• Check that the correct gasket is available.

• Loosely assemble flanges. Ensure that flanges and bolt holes align and that flange faces are parallel. Ensure that the gasket is correctly positioned.

• Tighten bolts gradually, in sequence, to ensure even loading around the flange to avoid distortion. Ensure that washers are used under bolt heads and nuts.

• The sequence for 8 and above bolt holes is that the tightening should be done on bolts opposite to each other (180°).

4. Quick Release Joint

This type of joint is most commonly used in Sprinkler Irrigation Systems where quick engagement & disengagement of joints are required. In this system Jain PE Pipes and fittings are welded on one side with spigot & on the other side with socket having a Hydraulic rubber seal inside it. To make a joint, spigot coupler is pushed in to the socket coupler, clamped and is locked.

5. Joint Quick Connect

Jain Quick-Connect™ PE Piping Systems offer a multitude of advantages for end users in the fields of Agriculture, Industry, Mining, Drilling and Construction. This System is easy to work with due to its quick-connecting and disconnecting joints and will provide years of reliable and flexible service to the user.

6. HDPE Sure-Loc™ Joints

Jain Sure-loc™ joints are the new generation joints which are aimed at evolving an easy and quick jointing system without the need for butt, electro fusion or any type of mechanical joints. Jain Sure-loc joints are flexible in the sense that they are detachable. The joint integrity is achieved by rubber ring sealing. The joint is self restrained and does not require thrust blocking or anchoring to keep the joint from separating under pressure. It is an excellent joint for above ground installations as the joints can take care of the linear expansion and contraction of the pipe due to temperature variations.

7. Insert Type Joint

This type of joint is used where PE Pipe is to be connected with another system having metallic fittings such as G.I. Coupler or Flange. To make this type of Joint, PE Pipe is heated to a temperature of 120°C in oil and then Serrated Metallic Nipple is inserted into it and secured by Jubilee Clip to ensure a leak-proof joint. This type of joint is generally used in bore well application for connecting to submersible pump.

Trenchless - Horizontal Directional Drilling

This “State of the Art” technology is one which is used with PE pipe and enables placement of pipes with minimum disruption to surface activities and other underground services.

Horizontal Directional Drilling is ideal for installing infrastructure beneath Highways, Roads and Railway tracks, without affecting Traffic Load on these networks. The technology can also be used for crossing of Rivers, Streams, Lakes, Buildings & Other structures.

Jain PE Pipe is an ideal choice for horizontal and directional drilling applications. The inherent properties of PE accommodate all the desired performance characteristics needed for this demanding application.

Pipe in Pipe

In some cases of damaged M.S., C.I., D.I., SW piping system, rehabilitation by open excavation is not possible. These pipes can be renewed by PE pipes. Because of less frictional resistance, we can insert small diameter and structurally strong HDPE pipe in the old pipe without affecting flow carrying capacity.
