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:

  1. »hydraulic equipment of the STH TraceWeld® Plus
  2. »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.
