Transition - expands or narrows the conditional passage. Concentric adapters connect pipes vertically, eccentric adapters - along the lower generatrix.

Along with other elements of NPP pipelines, production of welded sheet transitions is carried out in accordance with the standards:

• STO 79814898 117-2009 Details and elements of pipelines of nuclear power plants from corrosion-resistant steel for pressure up to 2.2 MPa (22 kgf/cm2). Transitions welded sheet
• STO 95 119-2013 Details and elements of steam and hot water pipelines of process pipelines of nuclear power plants made of pearlite steels for pressure up to 2.2 MPa (22 kgf/cm2). Transitions are welded sheet.

The thickness of the processed products is up to 12 mm. Parameters of the transported medium with pressure up to 2.2 MPa and temperature from -60 to +350 C
