This standard ensures that piping junctions are reinforced to handle specific mechanical stresses in carbon steel systems. : Designed for secondary circuit pipelines of nuclear
is a Soviet-era industrial standard (Industry Standard) that specifies the construction and dimensions for welded straight tees with reinforcement pads . These components are primarily used in the pipelines of nuclear power plants (NPP) where working pressures and temperatures are relatively moderate. Technical Overview This standard ensures that piping junctions are reinforced
While the standard was originally established in 1984 by the USSR Ministry of Energy, it remains widely used in maintenance and legacy engineering projects. Its status is often described as having an in modern repositories.
