This is a workshop welding machine designed to fabricate fittings like bends, wyes (Y), tees and crosses (up to Ø 630 mm) by joining pipe segments, with the help of special clamps. All clamps opening/closing and locking movements are controlled hydraulically.
Composed of:
- a machine body with two hydraulically controlled carriages;
- a control panel on which we find the hydraulic controls (lever for opening and closing the carriages, clamps opening/closing and locking, milling cutter and heating plate movements), the electric and electronic controls (switches for the milling cutter and heating plate, the automatic electronic temperature control device, timer for the heating and welding phases, acoustic and visual indicator);
- a heating plate that slides on recirculating ball slideways;
- a milling cutter that slides on recirculating ball slideways, electrically controlled for levelling the ends of pipes and/or fittings;
- an upper cylinder, to be positioned on the clamps, for welding extra thick pipes and/or whenever it's necessary to use high pressures.

This is a self-aligning welding machine, suitable for welding drain pipes and ducts for the transport of water and other fluids under high pressure, up to Ø1200 mm.
The DELTA 1200 was designed in accordance to the Italian and international correspondent standards (UNI 10565, ISO 12176-1), and consists of:
- Machine body with a bearing frame on wheels, four clamps and two hydraulic thrust cylinders with non-drip quick couplings;
- Extractable heating plate with separate thermometer for reading the working temperature;
- Extractable electrically controlled milling cutter for levelling the ends of the pipe and/or fitting, with a safety microswitch, overload cutout, and emergency push button;
- Electrohydraulic gearcase with a clamp opening and closing lever, maximum pressure and discharge valves (useful also during the "Dual Pressure" welding), hydraulic hoses with non-drip quick couplings, a clamps fast movement button, a timer (for the heating and welding phases), an electrical panel with a ifferential circuit breaker, and a special connection for the electronic data-logger INSPECTOR;
- Milling cutter/heating plate support with an electrical panel with power outlets for the heating plate, milling cutter and electrohydraulic gearcase, an electronic thermoregulator for the control of the working temperature, a turn on/off push button for the milling cutter, and differential circuit breakers.

Butt Fusion Jointing
Butt fusion technology is the safe, reliable and favorable jointing for a wide dimension range.
GF Piping Systems offers mechanical, hydraulic and CNC-guided fusion machines for on site constructions and the workshop. The fusion areas of the pipes and fittings are heated to fusion temperature and joined by means of mechanical pressure, without using additional materials. A homogeneous joint results.
Socket Fusion Jointing
In this form of fusion jointing, which requires heating tools, the pipe end is inserted into the socket of the fitting; no additional material is used. The pipe end and fitting socket are heated to fusion temperature using a heating bush and a heating spigot, respectively, and are then pushed together.
GF Piping Systems offers a wide range of hand and mechanical guided fusion machines – also for the field-use. The pipe end, fitting socket and heating tools correspond in such a way that the necessary jointing pressure is attained during jointing, resulting in a
Electro Fusion Jointing
In the electro fusion process a heating wire permanently mouled into the fitting gets heated by current at a low voltage. The surrounding material around the wire gets melted and expands due to the warming. The melt starts closing the gap between pipe and fitting, leading to a heat transition to the pipe which also gets heated and melts in the welding zone. The pipe material also expands.
The increasing material expansion between pipe and fitting, which is hindered by the cold zones outside the welding zone, leads to a build up a welding pressure between pipe and fitting and a homogeneous welding connection emerges.

HF profile and tube welding units
Easy tubular pipes can also be manufactured by DREISTERN tube welding installations. Its true strong points may however be evidenced by demanding tasks. Should you, for instance, have to produce stainless steel tubes of outstanding quality or contoured tubes with complex cross-sections, then you ought to consult our specialists. Good solutions are seldom exclusively a question of modern plant components.
Laser profile and tube welding installations
For some profile and tube manufactures laser technology is still new territory. In fact, a lot of questions are being asked about this technology. The initial question is frequently: Is laser really the right solution?
More and more frequently our customers answer affirmatively.
TIG profile and tube welding units
An example: With our RSD50 thin-walled tube welding unit, we attain extraordinary diameter/ thickness ratios and excellent seam quality. Even without seam processing, the seam is hardly visible.
Composite tube manufacturing lines
Aluminum-plastic composite tubes are constantly being used in new applications. The reasons are quick installation, corrosion-resistance, and last but not least, lower costs. Hot /cold water pipes and chemical tubes are but a few of the many possible applications. DREISTERN cooperates with the leading extrusion manufacturer MAILLEFER Ecublens (CH) and supplies turn-key machines for very high productivity.
