HDPE Pipes and Fittings Techniques

HDPE and PP are thermoplastics with excellent properties for the application of water and sewer as for the fabrication of containers for liquids and solid materials.

Application And Features of HDPE Pipes

• Chemical industries
• Geomembrane for hydraulic applications (such as canals and bank reinforcements) and chemical containment
• Geothermal heat transfer piping systems
• Heat-resistant firework mortars
• Fireworks
• Water pipes for domestic water supply and agricultural processes
• Food & Beverage
• Water and Gas Utilities
• Shipbuilding

HDPE pipes and fittings are offering very cost-effective solutions for a wide range of piping problems in municipal, industrial, marine, mining and agricultural applications. It has been tested and proven effective for the above ground, surface, buried, floating, and sub-surface marine applications.

Pipes made of Polyethylene and Polypropylene has considerable advantages to other pipes materials like concrete, steel, ductile etc. one of these advantages is the high flexibility. Even in areas, which are highly affected by earthquakes, our pipes are hardly damaged in comparison to pipes made of other materials. Despite the flexibility of the Krah pipes, they have a great capacity to carry loads, so that they are also suitable for road construction.

HDPE Pipe Fittings:

HDPE pipe fittings are designed corresponding to the required stiffness and in consideration of the welding factors. Every fitting can have any kind of pipe end and any jointing techniques including the integrated Electro-Fusion socket and spigot.

HDPE Pipe Joining Technique

Electro-Fusion Welding Machines

1. Quick welding
2. Welding device at a reasonable price
3. Welding possible in a narrow trench
4. Welding of bigger pipes possible from inside
5. Quick assembly by using several welding devices at the same time
6. Tensile strength
7. 100% permanent tight joint
8. Printed welding record
9. It is possible to use the Electro-Fusion welding device again immediately, even the pipe is still cooling

Welding Procedure

Generally, the Electro-Fusion socket and the spigot are already prepared for the welding. After the basic justification of the pipe the plastic foil, which serves as protection, is removed. Now the welding area is cleaned with a special polyethylene cleaner. The connection of the welding wire should be at the top of the pipes as this facilitates later welding. Now the spigot can be shifted into the socket. The pipe is justified, the inside support ring is put into the right position and the outer tensile band is tightened.

Other HDPE Pipe Joining Techniques

Extrusion Welding

HDPE pipe and/or fittings, which shall be connected, are jointed by a socket and spigot joint. Thus the two pipe ends are jointed with an extrusion welding device. The jointing method can be carried out inside or/and outside of the pipe. This jointing is most suitable for low-pressure gravity and manholes.

Heat Element Butt Welding

The pipes and fittings are joined with the help of a heating element butt welding machine. The ends of the pipes and fittings are butt-welded. This kind of jointing method is only recommended for pies and fittings with a maximum wall thickness of 150 mm and with diameters from 300 mm to 2500 mm.
