The welding control program supports the extended data encoding specifications under the ISO 121764 standard, (e.g. pipe and fitting traceability codes). To use this feature, the desired data must be enabled in the configuration menu, at Recording (see Section 6). Welding parameters can also be entered manually.
American Welding SocietyThe American Welding Society (AWS) was founded in 1919, as a nonprofit organization with a global mission to advance the science, technology and application of welding and allied joining and cutting processes, including brazing, soldering and thermal spraying. AWS strives to move the industry forward in both thought and action, as well as inspire new generations to see the exciting career
Control units should include safety devices to prevent voltages greater than recommended by the manufacturer. The safety device should operate in less than 0.5 sec. The user should check the suitability of the control unit for use with the fitting supplier. (REF:PIPA Recommendations for Electrofusion Welding Specifications)
Butt fusion or electrofusion welding for joining PE pipes Pipe structure - whereas in butt fusion welding the pipes to be joined must have the same wall thickness, with electrofusion a difference in wall thickness can be accommodated. Electrofusion can also be used to join certain typesof multiple layer pipes, e.g. nylon lined polyethylene pipe for the conveyance of fuel.
Double Containment Piping Systems - Aetna Plasticsthermoplastic welding techniques such as socket, butt or electrofusion. It can handle pH from 1-14 and is the most ductile and abrasion resistant thermoplastic material. Ethylene chlorotrifluoroethylene (E-CTFE) is commonly known by its trade name, Halar®. E-CTFE is a 1:1 alternating copolymer of ethylene and chlorotrifluoroethylene (CTFE). It

Electrofusion Installation Procedure ManualDue to the amperage draw of electrofusion fittings, use of extension cords are not encouraged but in the event it be- comes necessary to use one the following lengths and wire gages are recommended:Cord Length Wire Gage 25 ft. #10/3 wire (6 mm2) 50 ft. # 8/3 wire (10 mm2)
Electrofusion Pipe Joining Electrofusion Installation 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.
DV-8611BN0627. Exposed wire technology for optimum heat transfer between the fitting and the pipe during the electrofusion process. Available with 4.0 mm (40 Volt) and 5.7 mm (80 Volt) terminal pin connections to suit market requirements. Manufactured from

How To Make Proper HDPE Electrofusion JointsElectrofusion fittings can be installed in ambient temperatures as recommended by the manufacturer. A typical qualified temperature range for installation is 14°F minimum to 113°F maximum. Some manufacturers have lower and/or higher temperature limits and will state their qualified range in the technical specifications.
Electrofusion fittings can be used to connect Pexgol cross-linked polyethylene pipes. The pipes and fitting are connected by means of fusion welding creating a leak-proof seal. Theres no need for a sealing ring. During the electrofusion process a current is transported through a heating wire.
