OIL & GAS / REFINING
SCORE VALVES’ standard and custom solutions for Oil & Gas and Refining are found in all industry sectors including upstream, midstream, and downstream. Worldwide installation by all major end users is supported by our comprehensive butterfly valve product line from the rugged, non-rubbing TRICENTRIC® triple offset design, to the economical HIGHSEAL® designs. SCORE VALVES’ application experience includes topside isolation and control, pipeline distribution, downstream distillation, hydrotreating, sulfur recovery, and tank farms. SCORE VALVES’ design and manufacturing experience in a variety of oil and gas and refining applications has led to the development of custom upgrades and product versatility unmatched in the industry.
Sulfur recovery processes require triple offset valves to reliably operate as isolation and control valves for acid gas, combustion air, reactor bypass, sulfur rundown, switching lines, and sulfur tail gas block valves. Application media often requires substantial experience in material selection for corrosive and hydrogen-induced stress cracking resistance in compliance with NACE MR0103 and MR0175, as well as specialty options including steam jacketing and tracing to prevent sulfur solidification. For applications prone to media buildup in bearing areas, options include outboard, purged, lubricated, and energized seal bearings. Reduced port valves, which ensure an effective flange gasket seal, are available including stocked sizes from 4”×3” to 12”×10”.
TRICENTRIC® triple offset valves are used to help mitigate the risk of contamination and product loss for isolation of matrix manifolds; loading and unloading stations; storage tank inlet and outlet valves; and storage tank overflow lines.
TRICENTRIC® triple offset valves are used in natural gas dehydration and pressure swing absorption units; compressor stations; storage tank inlet and outlet valves; and downstream distribution pipelines.
TRICENTRIC® triple offset valves are used in flare isolation and flue gas desulfurization processes including corrosive environments with extreme temperatures to 1,400°F and large valve sizes to 84” in heat and oxidation, carburization, corrosion, and sensitization resistant material grades including 321, stainless steel, 347 stainless steel, and high nickel alloys.
TRICENTRIC® triple offset valves are installed in amine treating processes in coker sulfur recovery units that require resistance to hydrogen-induced cracking with material selection to NACE MR0103 and erosion with all metal construction for tight shutoff to maintain process efficiency.
TRICENTRIC® triple offset valves are used in upstream SAGD (steam-assisted gravity drainage) and oil and gas well production applications. These processes require triple offset valves to reliably operate as isolation and control —for oil, gas, steam-diluent extraction or injection in a corrosive and erosive environment—which requires substantial experience in material selection for corrosive, erosive, and Chloride- and Hydrogen-induced stress cracking resistances that are in compliance to NACE MR0103 and MR0175, as well as specialty options such as cobalt hard surfacing.
