Definitions

  • the invention relates to butt weld connections between two cylindrical tubes with the features of the preamble of claim 1 and a method for producing a butt weld connection with the features of the preamble of claim 2.
  • Such butt weld connections are used in pipe systems, the interior of which, for example, for electrical reasons, is free of foreign particles should, as is the case with encapsulated high-voltage switchgear and gas-insulated pipeline systems.
  • Gas-insulated pipeline systems consist of a tubular inner conductor and a tubular outer conductor. They are prefabricated in sections and then installed.
  • Butt weld connections are often used to connect the individual sections of the outer conductor. When welding these pipeline sections it must be ensured that no welding particles get into the interior between the inner and outer conductors. To prevent this, so-called weld pool fuses are installed.
  • the tubular ring has one in addition to the two grooves into which sealing rings are inserted further groove, which is located after pushing on the pipe ends below the weld to be made. When welding the pipes, dripping metal and other welding residues collect in this groove.
  • the invention has for its object to design the seal of the tubular ring against the pipe ends so that the assembly effort as little as possible is.
  • the seals consist of a shrink connection between the respective pipe end and the tubular ring.
  • the procedure is to use a tubular ring whose outside diameter is larger than the inside diameter of the pipe ends, and in order to produce the seals in the form of a nes press fit the pipe ends are successively shrunk on this ring.
  • This procedure enables the first pipe end to be positioned exactly over the center of the groove.
  • the pipe end that has been pushed on first serves as a stop for the pipe end that is then pushed on.
  • the butt joint of the two pipe ends is thus exactly above the center of the groove, so that metal or other welding particles dripping down during welding are safely caught in the area of the groove.
  • the figure shows in the upper part a butt weld connection between two pipe ends 2 and 3 of a pipeline system and a tubular ring 4 with a circumferential groove 5 arranged directly below the weld seam 1.
  • the ring 4 forms a press fit with the pipe ends 2 and 3.
  • the inner edges of the tubular ring 4 are rounded.

Abstract

Pour le soudage bout à bout de tuyaux, notamment de conducteurs extérieurs tubulaires (2, 3) d'une installation de conducteurs tubulaires isolés par gaz, servant au transport d'énergie, on utilise, comme protection contre le bain de soudure, un anneau tubulaire (4) pourvu d'une rainure périphérique (5), sur lequel les extrémités de tuyaux à souder sont emmanchées. Ce type d'étanchéité assure un positionnement précis de la rainure périphérique sous le joint de soudure (1).
