"Turboatom" certified the new technology of welding equipment

For certification of a new technical process on the basis of regulations adopted in the nuclear industry was founded Plant Certification Commission headed by the chief welder Alexander Vavilov and compiled a "certification program".
Connection tube-tube plate is used in the manufacture of condenser for the turbine K-1000-60 block No 3 of the Rostov NPP (Russia). This compound is very stable, the technology of its execution consists of expanding operations, pruning, trimming pipes, grease and welding. Welding quality depends primarily on how you performed prior to her surgery.
Feature of the connecting pipe-pipe board that the welding of pipe made of titanium alloy of thickness 0.5 mm requires a snug fit a tube to tube sheet and accurate trimming adjustment. This operation can be performed only on specialized equipment, so the plant has acquired machine for cutting and tube expanding the Italian firm "Maus" and the machine orbital welding of pipe joints, tube plate company "Polysoude" (France).
Today technology is certified and can be used for primary production.
