Electrofusion and Butt-Welded Fittings

Iplex stocks a comprehensive range of Fusion Plast electrofusion and butt-welded fittings. The Fusion Group have been providing high quality products and innovative solutions globally since 1971. Their long history of supporting their products with state-of the-art installation equipment and knowledgeable technical support, make them a valued partner to Iplex.

Iplex carries a large amount of stock nationally and has access to significantly more bespoke polyethylene fittings. We have a strong relationship with Fusion Plast and with other expert manufacturers, as well as having our own polyethylene fabrication facility with capabilities of manufacturing fittings up to 2000mm OD. This makes it easy for you to select Iplex as your chosen partner.

Advantages

Features	Benefits
Ease of use	The suite of installation equipment readily available to you makes for reliable and economical installation techniques.
Strong	Fusion Plast PE Fittings are proven globally and locally as a reliable selection for the toughest environments.
Abrasion and corrosion resistant	PE has high abrasion resistance and Fusion Plast fittings are usually made from the same polyethylene materials as the pipes. This means that the superior abrasion resistance of the pipe system is better than other materials.
UV stable	Fusion Plast PE fittings resin formulations contain carbon black to inhibit UV degradation. Carbon black imparts high UV resistance over long periods especially in harsh Australian environments.
Lightweight	Fusion Plast PE fittings are easy to transport and use in some of the most difficult in-trench, overhead, above and below ground conditions.

Temperature Effects

The ‘Design Life’ of Fusion Plast compression fittings is 50 years when used to transport fluids at 20°C at a maximum pressure of 16bar. The 50 year period is an historic and somewhat arbitrary figure, however the actual lifespan of fittings is expected to be many decades longer. Fusion Plast PE fittings can be used at temperatures above 20 °C, however the pipe and fitting pressure capacity is reduced.

The fittings are also ideal for sub-zero temperatures above -20°C Celsius.

Chemical Resistance

Fusion Plast PE fittings are made from the finest grades of polyethylene PE100 and hence share the chemical resistance of the parent pipes. When determining suitability for the transport of fluids, it is important that the compatibility of all materials coming in contact with our PE pipes and fittings is checked using the Iplex Chemical Resistance Tool

Standards and Approvals

AS/NZS 4129:2020 Fittings for polyethylene (PE) pipes for pressure applications

AMI-20303-FUSION-Group-ISO Type 5 Certificate of Conformity and Schedule

Colours and Markings

Black bodies.

Usually polyethylene fittings contain carbon black for UV stability thereby giving them their colour.

Range and Dimensions

Iplex's polyethylene Fittings range in sizes from 16mm up to 2000mm in some instances.

Handling & Storage

Fusion Plast fittings are often used above ground in harsh environmental conditions. For information on handling and storage, please refer to our industry website at www.pipa.com.au (Ref: POP001 and POP005). These documents can also be accessed here.

Installation & Testing

Fusion Plast has literature available specifically related to electrofusion and butt-welded fittings. For further details, contact our expert sales engineers.

The Fusion Plast range is compliant with AS/NZS 4129 which has extensive pressure, mechanical and material test requirements. Internal pressure testing limits are consistent with the requirements of the pipeline.

FAQ

Does the whole Fusion Plast fittings range have 16 bar pressure capacity?

One of the advantages of the Fusion Plast range is that it actively includes even higher pressure rated fittings as stock items. Don’t hesitate to ask for SDR9 (Pn20) and SDR7.4 (Pn25) fittings as we can get them quickly!

What sort of tools do I need for installation?

Tooling is usually a necessary part of successful installation of electrofusion and butt-welded fittings. There are strict guidelines/standards that need to be adhered to. This included AS/NZS 2033 which mandates proper installation equipment under Australian legislation. For more details on what is required, please refer to our industry website at www.pipa.com.au (Ref: POP001 for electrofusion and POP003 for butt-welding.) These documents can also be accessed here.

What is the temperature range of the fittings?

The pressure ratings of polyethylene pipe systems are usually expressed as a PN rating that is determined according to the operating pressure for water at 20°C. Polyethylene pipe systems need to be re-rated if the temperature of the pipe-system, or the medium being transferred through it is different to this. This information is available at our industry website at www.pipa.com.au (Ref: POP013) These documents can also be accessed here.

Are the fittings resistant to chemicals?

If the parent material is just polyethylene, then the chemical resistance will match that of the parent pipe. Caution is required if the fittings have any other materials. E.g. PE-Brass transition has multiple materials that need to be considered.
