HDPE Electrofusion Coupler / Coupling

HDPE Electrofusion Coupler / Coupling
Product Details

Product Details:
Electrofusion of HDPE uses electrofusion fittings which have small copper wires coiled around the inside. Electric current is then run through those wires using an electrofusion processor in turn melting the HDPE on the inside of the fitting and the outside of the pipe.

SUNPLAST company is able to provide wide range of electrofusion fittings available from DN20mm to DN630mm, including: equal coupler, reducer, equal tee, reducing tee, elbow 90°,elbow 45°.,etc.. Our HDPE electrofusion fittings are made by superior quality PE80 or PE100 raw material which is approved by PE100+ group, and they are mainly used for HDPE gas & water pipeline system.

SUNPLAST HDPE electrofusion fittings can fully comply with EN12201-3, EN1555 & EN ISO 15494 standard. By comparing other HDPE pipe fittings (socket fusion fittings, butt fusion fittings.,etc.), HDPE electrofusion fittings have following advantages:
※ Inner diameter of the pipe remains same.
※ Equipment mobility(low weight/low cost), so can be moved around easily.
※ High performance.
※ User friendly, fully automated, so need of highly skilled operator not required.
※ No weakening of material strength.

SUNPLAST has a lot of stock for normal sizes, can be delivered in a short time!!

※ What's the main difference between electrofusion & conventional heat fusion?
A: The main difference between conventional heat fusion and electrofusion is the method by which the heat is applied. In conventional heat fusion (butt, saddle and socket) joining, a heating tool is used to heat the pipe and fitting surfaces. The electrofusion joint is heated internally, either by a conductor at the interface of the joint or by a conductive polymer. Heat is created as an electric current is applied to the conductive material in the fitting. PE pipe to pipe connections made using the electrofusion process require the use of electrofusion couplings.

※ What does "electrofusion" mean?
A: Electrofusion is a method of joining HDPE pipes using special fittings that have 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 (typically 40V) 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. The assembly is then left to cool for a specified time.

※ What pressure rating can SUNPLAST provide for HDPE electrofusion fittings?
A: SUNPLAST HDPE electrofusion fittings be provided in SDR11, with pressure rating of PN12.5bars (for water) & PN4 bars (for gas) for PE80 fittings, PE16bars (for water) & PN10bars (for gas) for PE100 fittings. 

※ How can electrofusion coupler be used for?
A: HDPE electrofusion coupler is mainly used for the connection of one HDPE pipe to another HDPE pipe welded by electrofusion welding machine.
