Specific attention is given to products in other than day-to-day used material, i.e. carbon steel. In particular: low temperature carbon and low alloy (nickel) steels, chrome-moly low alloy steels, austenitic and austenitic-ferritic duplex stainless steels, nickel alloys. Basic standard of reference is API 600, but also EN 12516 can be referred to. Materials are either to ASTM/ASME standards or to EN standards, either harmonized or calculated to design conditions.
Pressure classes are normally ranging from 150# to 300# and 600#. Flanged or butt weld ends configurations are both available. Size range depends on pressure class requirements, FLUITEK ORSENIGO VALVES having no limits in relation to market requirements.
