Coating applied through this process increases the durability and improves the performance of ball valves. This process of metallic coating prevents the wear and tear caused by corrosive and/or abrasive action of the fluid transported, protecting all surfaces. The final coating is mainly characterized by high density and high hardness, high bond strength (test adhesive fails before coating), a reduction of any porosity, limited level of surface roughness and high wear resistance. Equipment n° 1 Sandblasting unit up to 56”. n° 2 Coating systems (HVOF process) up to 56”. n° 1 Quality Control Laboratory Types Tungsten Carbide Tungsten Carbide – Chrome Alloy Chrome Carbide Features Thickness from 120 to 400 µm Hardness from 900 to 1400 HV Tests Micro hardness of 900 – 1400 per ASTM E384 Porosity < 1 percent per ASTM E1920/E2109 Bend test per ASTM E290 and per NORSOK standard M-630 EDS NHF2 Bond strength in excess of 70 MPa (10 000 psi) per ASTM C633 Benefits Reliable sealing for metal-seated ball valves in HIPPS and other critical applications Standardized design for contaminated fluids and broad temperature range Predictable, low torque performance Long life cycle No maintenance High wear resistance at design seat load High erosion resistance in high-velocity fluids with particles such as sand, weld residue and other foreign matter Member of De Tomi Via Vicenza, 20 21040 Oggiona S.Stefano VA (Italy) +39 0331 734640 info@detomi.com Linkedin Youtube Links Company Why De Tomi Services Contact News and Events Video 16 Apr 2019 De Tomi We Think Round 3 Mar 2019
