Recently, RAYS successfully delivered a new C-type PIG VALVE for a foreign end-user, which will be used in an important pipeline project in the Arctic, contributing to the global energy strategy. The PIG VALVE is a new type of valve that serves as a transmitting and receiving device for pipe cleaners, and it also functions as a universal ball valve. With the use of pig valve and the corresponding pipe cleaners, pipe cleaning, emptying, isolation and sequential…
Introduction of Fully Welded Ball Valve Fully welded ball valve (soft and metal seated) base on welded valve suitable for Oil & Gas production, processing, transportation, distribution, chemical and petrochemical refining on the above ground and below ground installations. The world famous design is the Cameron T31 ball valve. Technologies of Fully Welded Ball Valve Trunnion ball valves have the obturator bounded by trunnions which do not allow axial displacements of the ball itself in the flow direction; line pressure…
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…
Introduction In this article, you will learn about the different applications of high pressure ball valve API 6D. Design pressure from 20 bar (g) to 1035 bar (g), in combination with other service conditions in hydrocarbon processes, refining, petro-chemistry, determinates ball valve construction, and material selection. The construction of the valve type includes: Cryogenic Ball Valve, LNG Ball Valve, Refining Ball Valve, Liquid Nitrogen Ball Valve, also include Control Ball Valve with Actuator motor. This application can exist in combination…
In recent years, the FPSO (floating production, storage and offloading tanker) market has been very prosperous, and major shipyards in the world have joined the FPSO constructions. RAYS won a bid and successfully delivered the FPSO project for EPC: Samsung Heavy Industries. The end user of this project was India’s Reliance Group company. The main valve types of this project include: floating ball valve, globe valve, and dual plates check valve. The materials of the valve include: Stainless Steel A182…
Introduction: Heating to boiling points, catalytic and hydro-treatments are some of the refining processes necessary to separate crude oil into storable fractions like marketable oils and condensate; most of these processes at high temperature, from 121°C to 1100°C (249,8°C to 2012°F), the High Temperature Ball Valve Metal Seated will be a better solution. RAYS can provide the metal seated ball valves engineered to withstand and exceed high temperature applications, with specific constructions and duly selected materials also suitable for geothermal…
Introduction In order to improve the control of volatile organic compounds (VOCs Control), RAYS has launched a full range of Fugitive Emission low-leakage Gate valves, Ball valves, Globe valves, and Butterfly valves that meet API 624 and API 641 standards, also can be ISO 15848, TA-LUFT, MESC SPEC 77-312. Fugitive Emission Low Leakage Valves Fugitive emissions are gas or vapor emissions from pressurized equipment that result from faulty equipment, leakage or other unforeseen events.The majority of these emissions come from…
Do you want to know what the cryogenic ball valve with extended bonnet is and the tips of material choice and inspection? After reading this article, I believe that you will have a huge gain in the field of cryogenic ball valve design. When Natural Gas has to be separated into fractions or treated to protect equipment from contaminants (acids), sweetening and acid removal at -51° to -196°C (-59,8° to -320,8°F), are the final stage to do that, starting from…
The valves supplied by RAYS to a supercritical power plant 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, a power plant owner has full confidence and trust on our power plant valves for harsh conditions with the design / manufacture /…
Recently, a batch of high-performance top entry ball valves with DN150-DN500 and PN100-PN180 have been successfully produced and passed various tests in our RAYS factory. All the valves have been delivered to our foreign customers at the end of September 2020 and will be put into use for a large natural gas project. The valve body for this order is forged by integrated forging. Compared to casting, the mechanical property is more stable and reliable under the working condition of…
