The power plant valves supplied by RAYS to a supercritical power plant phase Ⅱ in Thailand have been successfully delivered.Prior to this project, the Thailand power plant owners all used European imported power plant valves for the key position of supercritical high temperature and high pressure. However, after many technical exchanges/product design ideas and quality tracking control norms, and the high quality valves supply in the last two years at the phase Ⅰ, a power plant owner has full confidence and trust in our power plant valves for harsh conditions with the design/manufacture/quality control. Background/Condition of the Power Plant Valve ProjectThe power station project is located in a power station unit on a famous tourist holiday island in Thailand. The project code is “SKIC TG18”, and the EPC contractor is “SCG”. The medium is high-temperature & high-pressure steam, and the highest pressure reaches 100 Bar (10 MPa) when the temperature of steam reaches 510℃.Order Specifications of the Power Plant ValvePower plant pressure seal electric gate valve, size & pressure are 12″ & 1500LB, main material is F91, adopt ROTORK actuator imported from EuropePower Plant Valve Design CharacteristicsOne-piece forged F91 body and the design life of 25 years. Strict quality control, screening out high-quality forging suppliers, raw materials and machining process inspection stage through PMI element composition analysis, RT, PT, and other non-destructive testing procedures to strictly control the quality of pressure contain parts. In addition, during the machining process, the quality and technics can be traced for all sizes.Testing RequirementsDuring the final finished product testing, SGS as the third party inspection was invited to witness the dimension and pressure testing. The qualified rate of finished products was 100%, and the products were shipped & delivered to the owners successfully. Introduction to Power Plant ValvePower plant valve is also called the special valve for the power plant. It is mainly used for cutting off or connecting the pipeline medium in various systems of the thermal power station. Applicable medium: water, steam, and other non-corrosive media. Compared with other valves, the power plant valve is characterized by high temperature & high pressure, unique pressure seal design, and the higher the pressure, the more reliable the sealing. Due to the special performance with technical characteristics and working conditions, the power plant valves have special characteristics which other products can’t replace.Structural Advantages of Power Plant Valve1. Pressure seal is adopted and both ends of branch pipe for valve body have welded connection.2. The valve seat & disc sealing surface are made of cobalt-based hard alloy plasma spray welding and with good wear resistance & abrasion resistance.3. The valve stem is made of special material which is treated by a special process and has good corrosion resistance along with scratch resistance.…

Recently, a batch of high-pressure pipeline ball valves of DN250-DN400 PN63-PN320 have been successfully completed in our RAYS factory. DN250 PN320 and DN300 PN320 passed the high-pressure nitrogen test of 32MPa for three cycles to meet the requirements in harsh working conditions. The DN400 PN63 metal seated ball valve passed the high-pressure nitrogen test of 6.3MPa for three cycles, and all products meet the Grade A zero leakage requirement in harsh working conditions. This batch of products will be delivered to Russia in upcoming days at an ambient temperature of minus 60 degrees Celsius YAMAL project put into use.Product introductionSpecial purpose metal seated ball valves and high-pressure pipeline ball valves are suitable for Class150 ~ Class2500, PN16 ~ PN420 various pipelines, used to cut off or connect the medium in pipelines. Through the choice of: carbon steel, stainless steel, alloy steel and other valve material – special purpose metal seated ball valve and high-pressure pipeline ball valve can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media. Manual, worm drive, pneumatic or electric operations are available according to customer needs.The high-pressure pipeline ball valve is designed and manufactured by: absorbing foreign high-pressure pipeline ball valves technology, adopting special sealing structure, using reliable sealing performance, realizing zero leakage truly, and passing the high-pressure gas zero leakage test requirements. Special purpose metal seated ball valve is designed and manufactured with our special structure, which can realize zero leakage. The ball and seat of the metal seated ball valve for special purpose have good shearing self-cleaning function, which eliminates the phenomenon of stuck resistance caused by dust particles sticking to the valve seal, and keeps the appearance of the conventional metal seated ball valve. The seal of this metal seated ball valve produced by RAYS is processed by supersonic flame spraying tungsten carbide superwear-resistant alloy technology. It has the properties of high hardness and ultra-normal wear resistance where the hardness is up to HRC65~80. Its service life is far longer than the traditional hard sealed ball valve, which is suitable for: organosilicon, polysilicon project, and other special working condition systems.Structural featuresRAYS developed and produced a special use metal seated ball valve with: the advanced supersonic spraying, nickel-based flame spray ball, and seat hardening technology. This is to prevent the valve at high temperatures rise to death, scraper device, such as patent structure, good sealing performance, completely fireproof structure design, natural anti-static structure design, the function of blocking and discharge etc., solved the hard particle medium under harsh conditions for sphere wear-resisting coating wear easily, fall off, medium coking, valve stuck, short service life, to ensure that the metal seated ball valve wear-resisting reliable seal under various temperature and pressure.Quality assuranceQA from the design of ball valves to the procurement, processing, assembly, testing, subsequent surface treatment, packaging, and shipping. This is not only to meet the company’s quality system requirements, but also for the third-party agencies/customer end-users to witness at the same time. Also, this is to ensure that every valve can meet all quality requirements when leaving the factory.Applicable standard specificationsDesign and manufacturing standards: API 6D, API 608, BS 5351, GB/T 21385Structural length standard: ASME B 16.10, GB/T 12221, GOST 28908Connecting flange standard: ASME B 16.5, GOST 33259, GB, JB, HG, SH, BS, DIN, JIS, etc.Test standard: API6D, API 598, GB/T 13927, GB/T 26480, JB/T9092, ISO 5208 GOST 9544…
