Electrofusion welding is the most common welding technique for joining HDPE pipes. Electrofusion fittings with implanted metal coils is placed around two ends of pipes to be joined, and current is passed through the coils. Resistive heating of the coils melts small amounts of the pipe and fitting, and upon solidification, a joint is formed.

SUNPLAST HDPE electrofusion fittings provide simple method of joining HDPE pipes in circumstances where butt fusion is not practicable, and they are commonly used for the construction and repair of water plumbing & gas distribution pipeline.

About HDPE electrofusion Coupler

HDPE electrofusion coupler, also called HDPE electrofusion coupling, is the most common & regular fittings that are used to join two lengths of poly pipe in a straight line, and it can also be used to join a long spigot fittings to a piece of pipe.

Made by 100% PE100 material, SUNPLAST HDPE electrofusion coupler can come with a size range from dn20~dn630mm. The diameter dn25mm to dn315mm can be in SDR11-PN16 bars, while the diameter dn355 to dn630mm in both SDR17-PN10 & SDR11-PN16.

The electrofusion coupling fittings are injection molded in one time, and conform to ISO-3,EN-3, AS/NZS , EN, EN ISO standard.

SUNPLAST keeps mass stock in demand for regular sizes, and customers’ urgent demand & prompt shipment request can be satisfied.

Unique features of SUNPLAST HDPE Electrofusion Fittings

Some of the unique features and advantages of SUNPLAST HDPE Electrofusion Fittings :

Barcode

All SUNPLAST electrofusion fittings come with barcode sticking on it. The installer just need to use welding machine scanner to scan the barcode, all welding parameter will be indicated in the welding machine automatically. This will make the welding process easily, and greatly reduce the welding costs & time.

Indicators

The pressure created by the expanding molten plastic in the jointing area inside the fitting during the electrofusion process will force out the indicator lugs. This is a visible sign that the necessary jointing pressure has been achieved.

Moulded-in welding parameters

Manual welding parameters are moulded into the body of all SUNPLAST electrofusion fittings. Information provided includes fitting size, material (PE80 or PE100), applicable pipe SDRs, weld parameters, and pressure ratings for gas and water applications.

Permanently marked batch number

The injection mould batch number is just one of numerous quality control identifiers on each SUNPLAST fittings. It is replicated on the fitting’s barcode.

FAQS

*Whats electrofusion?

A: Electrofusion is the combination of two words - electro - implying the use of electricity and - fusion - the joining of plastic pipe therough the application of sufficient heat to create melting. Electrofusion differs from other heat fusion procedures due to the method by which heat is applied. In typical heat fusion welding, the pipe or fitting surfaces are heated through contact with an electrically heated coated heater plate. With electrofusion, the joining interface is heated internally by a resistive heating element supplied with an electric current which melts the appropriate locations inside the fitting while it is held in contact with the piping. When performing this joining process, the fusion welding times will vary depending on the fitting, the pipe material and the sizes being joined. The use of an electrofusion box which supplies the correct electrical current for the fitting is always required to complete the weld. Both electrofusion saddle fittings and couplers are available. Electrofusion saddles and electrofusion couplers for sizes up to around 630mm pipe are commonly available for polyethylene (PE) materials. PPR electrofusion fittings are also available.

*Whats electrofusion couplings used for?

A: Electrofusion Couplings are designed toconnect two ends of High Density Polyethylene (HDPE) piping together in an electrofusion welding method,where butt weld cannot be performed.

*How does electrofusion jointing work?

A: Electrofusion is a method of joining plastic pipes by using fittings with built-in electric heating elements, which are used to weld the joint together. The pipes to be joined are cleaned, inserted into the electrofusion fitting and a voltage, of typically 40V, is applied for a fixed time depending on the size of the pipe and fitting being installed. The built in heater coils then melt the inside of the fitting and the outside of the pipe wall, which melts together to produce a very strong homogeneous joint.

* HDPE butt fusion fittings & HDPE electrofusion fittings, which one is better?

A: HDPE butt fusion fittings & HDPE electrofusion fittings, both are the most common used HDPE pipe fittings.

* Material Costs

The HDPE butt fusion fittings are regular much cheaper prices than HDPE electrofusion fittings. The HDPE pipes adopt butt fusion methods, no special coupler fittings needed , so less fittings will be requested, and much lower on material costs.

* Installation Costs

The HDPE electrofusion fittings can be welded in much simpler way, which can be used for the certain circumstances where butt fusion is not practicable. Less installation costs & labor costs for electrofusion, as well as electrofusion machine is much lower on prices.

* Reliability of Jointing

HDPE electrofusion fittings has a more reliable jointing than HDPE butt fusion fittings. The HDPE electrofusion fittings can weld in secondary times when a leak happens.

So, it is difficult to distinguish which one is better, because both of them reputes excellent performances. The HDPE electrofusion fittings can save installation costs and provider a more reliable jointing while HDPE butt fusion fittings are much lower on material costs.

Finally, it depends on the project size and type, and location of installation. Electrofusion fittings can be a better choice for smaller, tighter spaces where onsite welding is being used.
