Fabrication of piping

MANUFACTURE AND PREFABRICATION OF PIPES

We manufacture, prefabricate and supply piping and tubular systems, piping for water, gas and steam, piping systems for engineering, metallurgical, chemical plants and other production and technological equipment.

We perform bending and rolling of pipes cold and hot with dimensions of 16 - 377 mm, prefabrication and workshop welding of spools and subassemblies, production of special fittings, manifolds, etc.

We produce tubular spirals, transitions, elbows and reducers.

We manufacture large pipes, flues, air ducts, chimneys and dampers.

Maximum dimensions / weight: OD = 5500 mm, L = 28000 mm / 100 tons / pc

USED MATERIALS

The company does use advanced technologies in welding, hot and cold forming, heat treatment and testing of relevant materials as generally used for above mentioned equipment:

  • High Alloy steels alloyed high percentage with of Nickel (2-20%) and Chromium (0,5-18%) specifically elements to develop corrosion resistance or extreme temperature stability
  • (low) Alloy steels alloyed frequently Chromium-Molybdenum used grades P2, P12, P11, P22, P22L, P21, P21L, P5, P9 and P91
  • Stainless steels (chromium, chromium-nickel, and chromium-manganese-nickel stainless steel) alloyed with Titanium, Molybdenum, Nobium, according ASTM grades of group SA 240/240M, according SAE designation series 300 (austenitic chromium-nickel stainless steel), 400 (ferritic and martensitic chromium stainless steel)
  • Nickel alloys (INCOLOY® Alloy 800 H / HT. 1.4876 / 1.4958 / 1.4959. UNS N08810 / UNS N08811)
  • Carbon steels
