Tubular products, flanges & fittings

Components for urea plants, pump heads, valve stems, condensers, reactors, strippers, scrubbers. Equipment and parts in the dyeing industry, textile, paper and leather, chemical, pharmaceutical and synthetic fibre industries.

Components requiring excellent resistance to boiling, concentrated nitric acid, equipment and components exposed to highly concentrated chlorine solutions at elevated temperatures, components for urea plants.

Components in offshore, waste water, sea water desalination and chemical plants with aggressive chloride-containing media e.g. heat exchangers, separator parts, compressor and pump components, turbine blades.

For applications involving highly corrosive environments due to the presence of chemically aggressive media, e.g. for equipment and plants which are cooled by seawater and parts for offshore plants. In the chemical industry where resistance to the attack of pure acids as well as acids containing chloride ions (sulphuric acid in particular), of organic acids and mixed acids is required in the higher pressure and temperature ranges. The enhanced resistance to crevice corrosion permits use also for applications where incrustation must be expected, and / or where the formation of gaps cannot be avoided by design precautions.

Alloy 718 (UNS N07718) is a high-strength, corrosion-resistant nickel chromium material that offers high strength and excellent corrosion resistance, particularly in H2S and CO2 environments.  For applications requiring higher yield strength, consider our BOHLER L718 API-150ksi, which offers a minimum yield strength of 150 ksi. 718 can be used in high temperatures as it has high temp de-rating factors and maintains strength at elevated temperatures.  Several conditions of 718 API are available at vSM. We offer the NACE/API 6ACRA versions at 120 ksi min yield as well as the 150 ksi high strength version.  Both tempers are suitable for sour service and can be used for pressure containing and pressure controlling equipment in corrosive environments. Typical applications include packers, safety valves, pumps, hangers, connectors, and fasteners.
