Welded support structures

Along with the manufacture of machinery and equipment, stainless steel tanks and machining of parts, Hraninvest-Hranmashcomplect AD is also a longtime manufacturer of welded support structures, air ducts, filters, silencers, foundations for the machine building, power industries and many other applications.

The available manufacturing facilities were refurbished and renovated, and today we have the most advanced welding equipment from Fronius and Kempi for E, WIG and MIG-MAG welding. In addition to this modern welding equipment, we also have facilities for welding of very large structures – production hall of height 12 m and clearance of 8 m, equipped with two bridge cranes of lifting capacity 12 t.

The company has implemented certified welding procedures in accordance with ASME and EN ISO 15614-1 for S235, S275, 304L, 316L, duplex steels and employs qualified welding personnel certified to ASME and EN 287-1 for the above welding methods.

Welding processes are performed under the supervision of qualified international welding engineers (IWE). Welded structures are controlled by qualified and certified personnel (EN 473). Welded joints are checked by visual inspection, non-destructive and destructive testing.

Welded structures, depending on customer requirements, are cleaned by grit blasting, sand blasting or bead blasting, and then coated with corrosion-resistant materials. Coating processes (environment and coat thickness) are controlled by special means from ELCOMER and use of methods in compliance with the requirements of European and international standards.
