Hardide-MFV Develop New HT/HP Subsea Valve Coating

first_imgHardide Coatings and Master Flo Valve (MFV) have developed a new solution to protect high temperature, high pressure (HT/HP) subsea choke valves.The valves are the first of their kind to feature the Hardide-T coating, which can be applied to choke valve stems so they can withstand temperatures up to 400°F and pressures of 20,000 psi.Canada-headquartered MFV found that alternative hard coatings previously applied to the stem assembly were not rated to sufficiently high temperatures. The challenge was to have a durable coating with a completely smooth finish to form a tight metal to metal seal.The two companies worked together to engineer a solution and develop a manufacturing process plan.Philip Kirkham, CEO of Hardide Coatings, said: “The subsea market is constantly evolving and we must react to the changes. Developments in coating technology for HT/HP applications were essential and we have worked with MFV to create the right solution for them. Its success has been demonstrated by qualification to all API requirements and deployment deepwater for a major oil and gas operator.“Hardide-T is one of our toughest coatings and has overcome a key challenge for MFV. It is used on two of their product lines and has the potential to expand into other subsea choke valve sizes and models with HT/HP requirements.”Hardide Coatings and MFV oversaw the manufacturing process and fine-tuned it to ensure specific surface finish and geometrical tolerance requirements were met.The coating has been applied to MFV’s P4-15K choke valve, which is rated from -20°F to 400°F and 15,000psi, and the P4-20K choke valve, which is rated to the same temperatures but a greater pressure of 20,000psi.They are typically installed on subsea production trees and are used for single/multi-phase production or water/chemical/gas injection. There is also an application for use on a capping stack, designed to be deployed in the event of a blow-out situation.last_img read more


first_imgA CO Donegal man has been sent for trial, accused of giving illegal loans to Sean Quinn’s family which later led to the collapse of the Quinn empire.Willie McAteer, 61, is the former Finance Director with Anglo Irish Bank.Former chairman and chief executive Seán FitzPatrick and the bank’s former Managing Director in Ireland Patrick Whelan, 50, also appeared in court in Dublin today to face the same charges. They have all been charged with unlawfully helping a group of investors, including six members of the Quinn family, to buy shares in Anglo Irish Bank in 2008.Mr FitzPatrick, of Camaderry, Whitshed Road, Greystones, Co Wicklow, Mr McAteer whose address was given as Auburn Villas, Rathgar, Dublin, and Mr Whelan with an address at Rachra, Coast Road, Malahide, were presented with the documents outlining the State’s case against them.They are each charged with 16 offences under Section 60 of the Companies Act, accused of permitting Anglo Irish Bank to give financial assistance to Patricia Quinn, her five children and ten senior clients of the bank, who became known as the Maple Ten, to enable them to buy shares in the bank.Three detectives from the Garda Bureau of Fraud Investigation, who had charged the three earlier this year, signed declarations this morning stating that the documents had been served.None of the three former executives spoke during the brief hearing.All were remanded on continuing bail, but the conditions in the case of Mr Whelan were altered to enable him to suspend signing on at a garda station during periods he is out of the country if he notified gardaí.The case against the three is to be listed at the Circuit Criminal Court for mention between now and December.A man who said he was homeless and wanted to hand a letter to Mr FitzPatrick refused garda requests to leave the area and was arrested.DONEGAL MAN SENT FOR TRIAL ACCUSED OF GIVING ILLEGAL LOANS TO QUINN FAMILY was last modified: October 8th, 2012 by BrendaShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:DONEGAL MAN SENT FOR TRIAL ACCUSED OF GIVING ILLEGAL LOANS TO QUINN FAMILYlast_img read more
