Prefabrication

Prefabrication of pipelines and bending of pipes

Within over fifty years of activity in the power industry and general industry in the scope of pipeline assembly we have learned that in order to maintain the leading position on still changing market, it is necessary to care for innovative character of products and technologies. Our previous offer concerning pipelines has been completed by pipe bending by means of induction method and cold bending, with heat treatment and prefabrication of pipeline elements, including shot blasting, painting and packing.
Expanding our Manufacturing Centre in Jaworzno we are not investing in machines, but in the value which is most important for us – satisfaction of the customer and professionally performed tasks (turnkey).

Pipe bending in 3D

The advantages of such bending system are: high accuracy of shape, less perimeter welds in relation to the conventional method and possibility of ordering of individual elbows.

 

 

Heat treatment

Electric furnace for heat treatment, 2 rods with cooling systems and basin for solution heat treatment.

  • Dimensions (L x S x H) 10 000 mm x 5 000 mm x 2 000 mm
  • Maximum temperature T = 1200°C
  • Maximum charge weight 25 000 kg

 

 

 

Pre-assembly of elements in spools

Department of Pre-assembly of Pipelines has a possibility of pre-assembly of finished pipeline systems in spools. All individual components of the pipeline, such as elbows, tees, diminishers, flanges and connector pipes are assembled into finished installation units according to requirements of the Customer.
