Pipelines made in the Porta Marine Service Sp. z o.o Company’s halls are welded according to our own technology recognised by Classification Societies using the following methods (acc. to EN 24063/ISO 4063):

  • 141 (TIG)
  • 135  (MAG)
  • 136
  • 141/136
  • 135/136

Welded materials:

  • carbon steel (S235JRH, S355, etc.)
  • high alloyed steel (304, 304L, 316, 316L, etc.)
  • Copper alloys (CuNiFe)
  • Aluminium


We successfully implemented a technology of manufacturing 3/4” and 1/2” ferrules using the Flowdrill® chipless threading and drilling technology. This technology allows us to make extremely tight connections (up to 300 Bars) without the application of significantly more time-consuming ferrule welding.


The Porta Marine Service Sp. z o.o Company has at its disposal devices used to make a full scope of Victaulic-type pipe connections.
