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 RAYS’ power plant valves for harsh conditions with the design, manufacture and quality control.
Project outline:
The 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 and high-pressure steam, and the highest pressure reaches 100 Bar (10 MPa) when the temperature of steam reaches 510℃.
Order specifications of the products and materials:
- Power plant pressure seal electric globe valve, size & pressure are 10″ & 1500LB, main material is F91, adopt AUMA actuator imported from Europe, and model is SA16.2-AC01.2-CK40.2(15-1)-F40.
- Power plant pressure seal manual globe valve, size & pressure are 6″& 1500LB, and main material is F91.
- Power plant pressure seal swing check valve, size & pressure are 14″& 1500LB, and main material is F91.
The product design characteristics:
One-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 machining process, the quality and technics can be traced for all sizes.
Testing requirements:
During 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.
