polyethylene pipe fittings

Acu-Tech Piping Systems offers a range of electrofusion fittings made of polyethylene (PE), the advantages of which have been recognised in the gas and water industries. In general, PE is the material of choice for those who are looking for a lightweight yet tough, synthetic material that offers high resistance to corrosion and chemicals.

Characteristics of Polyethylene

High-grade PE (polyethylene) is one of the most commonly used materials for piping products. It is also one of the most durable synthetic materials, which has a long life expectancy – potentially up to 100 years in good conditions. Its durability and resistance to corrosion allows it to efficiently carry substances for many years without being affected by harsh environmental conditions.

Compared to other plastics, PE presents excellent flexibility and ductility that can withstand static pressures and perform under aggressive conditions. Since it is also a type of hard-wearing plastic, there’s no need to worry about rust. Most importantly, PE is not prone to biological growth and build-up, which can affect the quality of the substances passing through the PE pipes.

Pipe Jointing Through Electrofusion

To enhance the security and efficiency of PE pipes, the use of heat fusion strengthens their durability and makes them more compatible with existing piping accessories.

Among the various types of heat fusion, Acu-Tech offers PE pipe fittings compatible with the electrofusion jointing method. Electrofusion is the jointing process of pipes and/or fittings of the same connection diameter. Many industries consider electrofusion as one of the safest and most developed methods for welding PE pipes and fittings.

The electrofusion process uses heat from electricity to melt the pipe and create an entirely homogenous joint that is stronger and more durable than the pipe itself. All electrofusion welding of PE pipes should be done by a trained operator, as there are important factors that may compromise the efficiency of the electrofusion process if performed incorrectly.

Benefits of the Electrofusion Process

Electrofusion is the method of choice for below and above ground PE systems and for inaccessible installations of trenches, heights and other confined spaces. Electrofusion can also weld together pipes and/or fittings of different thickness.

Unlike PVC jointing, which uses chemicals or rubber seals, pipes welded by electrofusion fittings in the correct procedure do not have parts that will deteriorate over time. And since there are no chemicals involved in the jointing, PE electrofusion fittings are safe for use in the food industry.

Preparing Pipes for Electrofusion

To prepare joining surfaces, you must scrape the HDPE pipes with an appropriate pipe scraper recommended by your pipe and fitting manufacturer. Avoid using rasps, metal files, emery paper and other materials, as they are not suitable for poly pipe preparation.

It is ideal to remove the entire surface of the pipe over the indicated area to a depth of around 0.3mm. After scraping, wipe the surface with an authorised cleaning agent like Isopropanol poly welding wipes to remove any dust residue. The surface must be dry before proceeding with the electrofusion process. The result of a well-prepared pipe is a strong joint that can withstand heavy loads during installation and routine operation.
