    TUNGSTEN CARBIDE BALL VALVE COMPONENTS WITHSTAND SAND SLURRY TEST


    HOUSTON – Watson Grinding & Mfg. and Oil States Industries announce metal seated ball valve with tungsten carbide coating was unaffected by sand slurry test environment.


    The 2-1/16” 5,000 psi 4130 alloy steel ball valve with tungsten carbide coated ball and seat components spent approximately 50 hours in service.


    The API 6AV1 Class II test specification consists of 50hours flow with a sand slurry media flowing through the valve, then subsequently 500 open/closed cycles with sand slurry flowing through. The acceptance criterion of zero leakage was met. Test media was a water/sand mixture; with which the specification has strict requirements for sand particle size, sand content, and viscosity. Test temperature was ambient, pressure was 5000psi maximum.
    The purpose of the R&D was to study the amount of leakage. This test was performed for no specific application; however, emergency shut-down valves (ESDVs) require this certification.

    Titanium ball valve withstands environment testing

    HOUSTON – Watson Grinding & Mfg., Watson Valve Services, Inc. announce Barrick Technology Centre R&D titanium ball valve ball and seat with chrome oxide coating unaffected by test environment.

    The ½”-Ti/CrO ball valve spent approximately 480-hours in service at temperature and pressure over about 2-years. There was no catastrophic failure to the ½”-ball valve; a leak in the soft seal was the only issue. The typical autoclave temperature was 225°C (437°F) with total pressure approximately 455-psig for multiple pilot runs.

    The purpose of the R&D ½”-Ti/CrO ball valve was to study the level of corrosion upon failure. The test environments ran were the autoclave pilot programs for Goldstrike ore feed and Pascua Lama concentrate feed – both acidic at discharge where this valve was exposed (with approximately 20-g/L H2SO4 free acid and 60-g/L H2SO4 free acid). This valve acted as the primary discharge isolation ball valve which sees the hot acidic slurry but not duty cycled like the discharge valve.

    The metallurgical evaluation performed by the Watson Coatings Laboratory division concluded the chrome oxide coating was unaffected by the test environment with no excessive wear to critical parts.
