Duplex Instrumentation Fittings Manufacturer in India
Sawariya Metal Industries is a manufacturer, supplier, stockist and exporter of Duplex Instrumentation Fittings in different sizes, grades, specifications and finishes for industrial and engineering applications.
Duplex Instrumentation Fittings include seamless and welded instrumentation tubes together with compression fittings, connectors and valves used to carry process fluids and signals safely to instruments.
Duplex stainless steel has a two-phase austenitic-ferritic structure that delivers higher strength than standard austenitic grades together with good resistance to pitting, crevice corrosion and chloride stress corrosion cracking.
Typical applications for Duplex Instrumentation Fittings include oil & gas, chemical processing, petrochemical, desalination, marine applications, pulp & paper, heat exchangers, pressure vessels and general engineering.
Key Features of Duplex Instrumentation Fittings
