The Hürner CNC ECO 2.0 plastic pipe butt welding machine is available through Plasti-Tech Piping Systems, providers of world-class thermoplastic piping systems to the construction, civil, mining, irrigation, plumbing, gas and water-works industries in southern and sub-Saharan Africa.
The CNC ECO 2.0 from Hürner, leading German welding technology company, represents next-generation plastic butt-welding technology of the highest quality and durability, developed in compliance with the highest global industry standards.
“This computer numerically controlled (CNC) machine is available in South Africa from Plastic-Tech Piping Systems in 12 basic machine chassis models, which can join pipes as large as O.D. 1600 mm in diameter,” comments Brad Chamont, Plasti-Tech Managing Member, adding, “The unit is easily transportable and comes with a fully encased CNC hydraulic and control box of ingress protection (IP) of 54 and can handle pressures of up to 220 bar.”
The CNC ECO 2.0’s heating element is covered with an anti-stick coating and, along with the facing tool, is attached to the chassis of the unit on the hydraulic and control box. This configuration negates the need for any additional power distribution on the unit.
Throughout the welding process, the heating element temperature and pressure control are implemented in line with applicable standards, including DVS, UNI, WIS, NEN, etc. All parameters for a good quality, reproducible joint are carefully monitored throughout the welding process and the related data are saved to the unit’s internal memory, which boasts the capacity for up to 10 000 reports.
Additional features on the unit include a movement pushbutton, a tag printer and label tags, and front panel. “The pushbutton on the basic machine chassis of the Hürner CNC ECO 2.0 allows for movement of the unit while the welder stands alongside,” remarks Chamont. “This renders the machine a far more convenient setup than its competition, because it eliminates the usual back-and-forth between the hydraulic and control box and the chassis,” he says.
The standard version of the Hürner CNC ECO 2.0 comes with matching next-generation high resolution temperature-range-extended character display. The modern GT keyboard allows for easy input of component parameters and traceability data. Furthermore, each welded joint is easily labeled with the dedicated tag printer that comes as an optional extra. The printer prints a scratch-proof sticker that can be used as a label on fittings or joints.
“All next-generation butt-weld machines from the Hürner range are made to house additional extras and model upgrades,” says Chamont, adding, “This includes weld data recording and transfer, label printers, CNC automation, etc.”
Driven by data
The Hürner CNC ECO 2.0 also represents innovation in the line of user identification and access control in butt-welding technology. On this unit, user IDs and access control are not reliant on barcodes or scanners as is the case with traditional technology. “Data is made available to the hydraulic and control box by the error-proof and user-friendly RFID (radio frequency identification) technology, which makes it so unique.”
Regular input devices like the scanning pen and handheld scanner remain available as optional extras on Hürner’s next-generation units, which also carry a USB port for downloading welding data in short abstract form or in an extended PDF format or for archive in the Hürner DataWork format.
Hürner’s CNC ECO + 2.0 model features the HDC, or Hürner Distance Control, which is a sensing system for accurate verification of proper welding and welding process preparation.
Training & safety
While operation of the CNC ECO 2.0 does require any special qualifications, training on the use of these is necessary and is conducted at Plasti-Tech’s Edenvale premises. “Working at such high welding pressures with large pipes, design consideration for the operator’s safety is paramount,” comments Chamont, who goes on to say that “The units boast excellent operator safety features, including the radio frequency ID system that restricts unauthorized access, as well as the hydraulic system bypass valve that must be opened to relieve the pressure before the machine and weld can be inspected.”
“It is our recommendation that when the welder is operating the unit’s control box, there must be no interference by a second person in the welding zone, due to safety risks associated with high pressure and temperatures,” cautions Chamont. “We always ask our clients to ensure that only one person operates the unit during the welding process,” he says.
“The Hürner CNC ECO 2.0 embodies cutting edge German technology in the field of plastic pipe butt-welding. With its generous features and scope for adaptability and adoption of optional extras, we a proud to carry a range of machinery that speaks the language of Plasti-Tech’s customer base across sub-Saharan Africa,” Chamont concludes.
