Certified in the EAC Certified in the INTERGAZCERT Certified by the National Welding Inspection Agency (NAKS) 100 best products 2015

Application area

The unit is used to braze cathodic, drainage or measuring fasteners to the pipeline as an alternative to the thermit welding. Thanks to automatic control of the process of pin brazing the result is a strength joint of cable and metal construction.

Pin brazing may be realized on the constructions with wall thickness of 2 mm without decrease in working pressure. The staff is not required to have any special skills for this kind of work, the device practically excludes a human factor and allows to work in any weather conditions.

It is used with electrodes of EVP Mendeleevets.

  • more technological production in comparison with other types of connections;
  • there is no destruction of material to which pin brazing of the outlet is carried out;
  • allowed wall thickness of the base is less in comparison with other types of connections;
  • the process is maximum automated;
  • it doesn’t require high qualification of the operator;
  • the low voltage of the battery provides safety of the operator;
  • possibility of pin brazing in any position of the holder of electrodes.

Technical details

The installation consists of the battery, the control unit and the electrode holder. The battery and the control unit are in one sealed plastic case. The fire and explosion safe elements that have a large number of charge-discharge cycles and low internal resistance are used for the battery.

    There are two types of pins depending on construction design:
  • for pin brazing of copper cable lugs;
  • for threaded connection of copper.
