Product Description
Butt Welded Ends Low Temperature/Cryogenic Extended Stem Floating Ball Valve
Hastelloy steel ball valve structure is a hard-sealed ball valve. The valve is a split structure, and the ball and valve seat are installed from the side.
Valve body: Made of Hastelloy forged steel material. The chemical composition and mechanical properties meet the requirements of ASME standards.
The ball and valve seat are internal parts, which are completely exposed to the medium. A metal hard sealing contact is used between the valve seat and the ball.
The surface of the valve seat and the sphere adopts first surfacing welding of cobalt-based alloy (first thermal spraying of cobalt-based alloy, then tungsten carbide and then cobalt-based alloy, the thickness is more than 1mm, remelting treatment), and then the cobalt-based surface adopts the world's most advanced " Nickel-coated tungsten carbide supersonic thermal spraying and remelting process" hardening treatment. Improve the wear resistance, hardness and erosion resistance of the sealing surface.
WC is a kind of cemented carbide with high hardness, high strength and high wear resistance. Its grain size is generally below 0.2~1.0μm, most of which are below 0.5μ,m. It has the high hardness of cemented carbide and high-speed steel. Strength of. Its hardness is not less than HRC68, and the bonding strength is not less than 70.
The hard-sealed ball valve produced by our company uses nickel-coated tungsten carbide (a certain ratio of tungsten carbide is added to Ni60) on the valve seat and ball surface with supersonic thermal spraying. The thickness can reach 0.5~0.8mm. To ensure that the sealing surface is not affected by the medium and its particles; reduce the friction coefficient of the surface and improve the surface anti-wear performance. It has the characteristics of wear resistance, friction reduction, heat resistance, corrosion resistance, low friction coefficient, and anti-seize. It can improve the surface properties and increase the life span.
