Viega says that its ProPress® system for stainless steel obtained certification through the Technical Standards and Safety Authority (TSSA) for its 1/2” to 4” size fittings.

The system consists of stainless steel pipe, valves and fittings, and offers a fast, reliable, flameless way to make water-tight and gas-tight stainless steel connections.

The fittings were submitted for approval under the American Society of Mechanical Engineers (ASME) code for pressure piping, B31. This code outlines requirements for piping that is found in a variety of industrial applications including petroleum refineries, chemical, pharmaceutical, textile, paper, semiconductor and cryogenic plants.

This certification approves the Viega ProPress system for use with boiler piping, compressed air, chilled water and other piping applications. ASME’s technical standards improve safety and efficiency and are accepted in over 100 countries as operating standards.
