WELDING
E&E supplies and welds a wide variety of pipes, from different materials and dimensions.
PIPES WELDING
High-Density Polyethylene HDPE Pipes
Flexible, durable, light weight and very cost effective answer for problems on mining, gas, municipal, oil and underwater applications, a welded HDPE pipe has a zero leak rate. It is also an option more environmentally sustainable since it's composition creates a non-toxic and chemical/corrosion resistant pipe, designed to endure a long life. Can be applied on either trenched or trenchless installations methods due to its flexibility.
E&E is speciallized in HDPE pipes welding with machinery from diameter 90mm to 1200mm, in both butt fusion and electrofusion welding.
Our pipe welders are trained and certified following international standards.
- HDPE Butt Fusion
It is a welding process used to join two different pieces of thermoplastic. This process involves heating both pieces simultaneously and pressing them together in a controlled process. The permanent bond is achieved after the two pieces are cooled down.
Seeking versatility, our butt fusion welding machines are able to weld different pipe's diameters. The machines are then associated with clamps matching the pipe's diameter. At the end of the page, it is possible to find a correlation table between machines and diameters.
Eau et Environnement owns the following butt fusion welding machines, equipped with a data logger (LDU).

PT315

Powered by a metalic hanger arm and an electric winch.

PT1200
Diameter: From Ø450mm to Ø1200mm
Equipped with a hot plate and a monitoring system.
Powered by a metalic hanger arm and an electric winch.

- HDPE Electrofusion
It is a method of joining MDPE, HDPE and other plastic pipes using special fittings that have built-in electric heating elements which are used to weld the joint together.
After being cleaned, the pipes are inserted into the electrofusion fitting and a voltage is applied for a fixed time depending on the fitting in use. The built in heater coils then melt the inside of the fitting and the outside of the pipe wall, which weld together producing a very strong homogeneous joint.
