Stainless piping system certified

Viega's ProPress system received certification by the Technical Standards and Safety Authority for its fittings.


The Viega ProPress system for stainless steel obtained certification through the Technical Standards and Safety Authority (TSSA) for its 1/2- to 4-in. size fittings.

The system, consisting of stainless steel pipe, and 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.

The Viega ProPress system for stainless meets the ASME requirements for dimension, pressure and temperature ratings, materials, identification markings and service that demonstrate a high standard of safety. This certification approves the Viega ProPress system for use with boiler piping, compressed air, chilled water, and other piping applications.
