What is electrofusion process?

What is electrofusion process?

Electrofusion 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. Electrofusion welding is beneficial because it does not require the operator to use dangerous or sophisticated equipment.

How does electrofusion coupling work?

The electrofusion process works by introducing a controlled electrical voltage to the heating coil, which in turn generates heat to melt the fitting and pipe surfaces. As the polyethylene surfaces melt they also expand in volume to close any gaps between the pipe and fitting.

What are electro fusion fittings?

What is ElectroFusion Fittings? Electro Fusion is a method of joining plastic pipes together through electric heating methods. A particular type of fitting is used that has built-in electric elements which can be used to weld the joints. This type of fittings make the joint stronger.

What gas is used for fusion welding?

This process uses an electric arc created between an electrode and the torch nozzle. The electric arc ionises the gas (usually argon) in the chamber creating what is called a ‘plasma.

How do I join HDPE?

Heat fusion, the most common method used to join HDPE pipe, works by heating two pipe ends and pressing them together, creating a permanent joint that converts individual sections of pipe into a single, continuous line.

Which welding is not a fusion welding?

Answer is “Friction stir welding”

What is the difference between plastic welding and fusion welding?

In the plastic welding, also called the pressure welding, the pieces of metal to be joined are heated to a plastic state and then forced together by external pressure whereas in fusion welding, also called the non- pressure welding, the material at the joint is heated to a molten state and allowed to solidify.

Why choose Georg Fischer central plastics for electrofusion?

Where are electrofusion fittings made?

In 1984 Georg Fischer Central Plastics (formerly Central Plastics Company) began manufacturing electrofusion products in the United States for natural gas and other pressure piping applications. Many international standards exist for electrofusion fittings, testing, and joining equipment.

What is an electro fusion machine?

Electrofusion Machines In the electro fusion process a heating wire permanently molded 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.

What are the principles of electrofusion fittings?

Principles of Electrofusion Polyethylene (PE) Electrofusion fittings are manufactured with a precision-designed resistance wire heating coil mechanism. The wire heating coil is encapsulated by PE and located just below the fitting’s fusion surface. X-ray perspective of heating coil mechanism
