Hardide has developed a high temperature / high pressure carbide coating

       Hardide Coatings and Master Flo Valve Inc (MFV) Ltd. have developed a new coating technology for the protection of underwater throttle valves operating under high temperature, high pressure (HT / HP) conditions.



      The valve is the first use of this type of Hardide-T coating valve, the coating can be used for stem throttle, and it can withstand temperatures up to 400 ° F and 20,000 psi pressure.



      MFV of Canada found that the alternative hardcoat used in previous stem assemblies was not resistant to high temperatures.



      The coating is applied to MFV's P4-15K choke valve at a pressure of 15,000 psi and can withstand temperatures from -20 ° F to 400 ° F when applied to the P4-20K choke valve at the same rating Temperature, can withstand greater pressure, for the 20,000psi.



      Valves are usually installed on underwater production trees for single / multiphase production or water / chemical / gas injection. Can also be applied to the cap stack, the purpose is to occur in the event of an accident deployment.



      "The underwater market is evolving and we have to cope with this change," said Philip Kirkham, chief executive officer of Hardide Coatings. "It is critical to improve the HT / HP resistance of the coating. We work with MFV to find Out of the right solution. "
