  • connection is established in the size of the relatively small wall, the use of this technology ensures that there is no loss of the connection to the loss of power
  • the proposed method includes operations that are common for a non-permanent or end-user terminal: 3.1. Testing the billet of the pipe with hydraulic pressure at the source. 3.2. The center for the sizes and the end of the pipe. The end of the pipe should have a transverse cut of the pipe, the circumference of the tip of the pipe end is no more than 1.0 mm per 1 m of length. 3.3. The landing of the planted end of the trees. Combined landing, there is a compression operation as there is an external part of the end of the pipe, and there is no internal part (7).
