Performance tests (TAT) on industrial valves

Tre P Engineering has recently performed, with satisfactory results, Type Acceptance Tests (TAT) on big dimensions’ (36” and 48”) ball valves manufactured by DAFRAM SpA.

36" Valve

36″ Valve


48" Valve

48″ Valve



Testing has been executed according to Shell Mesc 77/300 (Procedure and technical Specification for Type Acceptance Testing [TAT] of industrial Valves); leakage and fugitive emissions tests, in particular, have been conducted on the minimum and maximum valves’ designated temperature ranges.

A gas burner has been used fot the high temperatures measurements (> 300 °C); to reproduce the low temperature phases (-50°C),  liquid nitrogen’s evaporation has been used.
