Main types of products

Our company specializes in package supplies for the nuclear power plants, which allows to minimize the installation and welding works on the site. The packages are formed both from bends, tees, adaptors, three-leg junctions and other fittings manufactured in our working areas, and with purchased parts.

A special feature of the control during manufacture of the packages for nuclear power plants is the developed destructive and non-destructive testing system, including two certified stationary x-ray chambers with a capacity of 320 and 450 kV with the equipment Yxlon.
