Corrosion is not only due to the make-up of the well fluid and adverse flow conditions but also due to the toxic chemical used during well treatment. Wells can have more than 30000 PPM of H2S. Deep well contains Carbon dioxide, Hydrogen sulfide and other corrosive fluids.

JVS offers Clad Choke’s/Valve’s in order to counteract the above flow conditions. The cladding process ensures the best output to maintain corrosion resistance imparted by the exotic nickel alloys and simultaneously maintaining the cost effectiveness of the overall project.

JVS offers clad choke valve to fulfill Oil and gas project requirements with competitive pricing and dependable delivery. Cladding or weld overlay of wetted surfaces of choke valves using Corrosion Resistant Alloys (CRAs) is a standard practice for ensuring fitness for purpose while still keeping costs manageable.

JVS Engineers is capable of cladding diverse products /geometries with different alloys to match stringent customer specifications over and above API 6A and NACE MR 0175 requirements.

JVS strengths:

• State-of-the-art automatic equipment (Pulsed Gas Tungsten Arc Hot Wire overlay)
• Tested procedures
