The Basic Description of STH Equipment
The hydraulic welding equipment STH are intended for butt welding of pipes from thermoplastic materials of dimensions of 50 – 900 mm, which is used especially for outdoor water and gas pipelines. Perfectly stable welds can be made thanks to the precisly defined pressure created by the hydraulic unit.
Communication software WeldManager
Original Dytron software allows communication with the following equipments:
- »hydraulic equipment of the STH TraceWeld® Plus
- »electrofusion welder SVEL 3500 Plus
The advantage of weld manager is data collecting from all equipment into one central information storage using a single program. This simplifies the recording and evaluation of welds made using different equipment such as e.g. STH and SVEL on a single project site.
Advantages of STH Series
Specially designed clamping jaws allow clamping and aligning of slightly oval pipes
Quick-couplers for fast connection and separation of hydraulic unit and basic unit
Removable fourth jaw of the STH 160, 250, 315 machines allows making of welds in hard accessible areas
Each hydraulic unit is equipped with a circuit/breaker for increased operator safety
A hoist with electric drive for easy handling of the mirror and trimmer is included with the STH 500, 630, 900
Welding mirror coated with titan oxide secures a long life cycle and good welding features
Flange Adaptor is used for clamping and welding of flanges
Pipe Support Roller ensures minimum moving pressure during welding
