SYSTEM INTEGRATION, CORE AREA OF OUR BUSINESS

Over the years we have built up significant references for System Integration packages namely for HIPPS and SUBSEA.

HIPPS SYSTEMS (SIL 3) require not only the actuated ball valves but the Logic Solver + Pressure Transmittors + HIMB and associated instruments, these can be supplied as individual items for the customer to install or into a skid housing all the items so it arrives ready to install and commission. The entire system iFat is carried out at MIR VALVE plant. Watch our video on iFAT of HIPPS System for ADNOC

SUBSEA SYSTEMS - we have completed supply for the actuated ball valves including the HPU + Control Panel + Back-up Storage Tanks c/w batteries + Solar Panels + Umbilicals + ABS Certification which are supplied as a complete unit and iFAT carried out at MIR VALVE plant. Watch our video of iFat of Subsea System for Saudi Chevron.

This is a very important part of our business model and we work with partners whom we have strategic partnerships with

DID YOU KNOW?

Hard facing (Tungsten Carbide Coating  / Chromium Carbide Coating) is applied to the surface of the ball and the sealing contact area of the seats to increase the hardness of the mating surfaces. These valves are metal-seated ball valves and can come in all designs, sizes and classes.


The application of hard facing is done through our approved sub-suppliers and there are very strict technical and QA/QC procedures that control the process. MIR VALVE has in-house own internal TCC/CCC procedures that address all specification requirements. Our Engineering also performs Finite Element Analysis (FEA) for the seat-to-ball contact.


Hard facing (TCC/CCC) is applied with HVOF method (High-Velocity Oxygen Fuel), and the thickness is generally 150 micron, but can also be 200 or 400 micron; HVOF is the most common method for hardening the surfaces of ball valves. Ball and seats with hard facing require a special lapping process (pictured) to match the parts and each seat is assigned to side A or B of the ball followed by internal QC steps to determine the sealing contact is correct prior to final assembly.


The opening and closing of the valve would require the two surfaces to slide against each other with a high amount of force (due to piston effect) and produce a sealing level when in the closed position as per API 6D, 6DSS, 6A, Rate B or C or D, as the customer specifications will define the sealing level. 

Therefore, the hard facing (TCC/CCC) would significantly increase the surface hardness of the two sealing components thus increasing the wear life of the contact surfaces. This also makes the surface far more resistant to scratch and gouge damage from flow debris, that is why they are required in abrasive service.
Typically, we see metal seats when required by the application, usually when long life reliability (Subsea, HIPPS), severe service (dirty), low maintenance (subsea), high demand (frequent cycling) is required  and when the temperature is a limitation for soft insert. TCC can be used in cryogenic applications (-196 deg C); while for high temperature valves the HVOF process doesn’t change, however since TCC can withstand a maximum temperature of +200 deg C, for higher temperatures, CCC  must be used as it can withstand a temperature of +500 deg C.


On a commercial note, when specifying TCC/CCC, it can have a high cost impact in all areas of manufacturing covering the application of the hard facing, QC, lapping processes and assembly, as well as overall, the ball valve requires a higher torque, a more robust topwork design and thus a more powerful actuator.
