Testing of steam condensate equipment supplied by OPEX ENERGOSYSTEMY
For one of the manufacturing plants, our engineers have selected and supplied a number of float steam traps of different flow rates and several pilot pressure reducing valves for steam from the model series of Japanese manufacturers. At the same time, steam traps and pressure reducing valves from manufacturers from other countries on the market were also purchased. Based on the results of the operation of all equipment, a manufacturer and supplier of steam condensate equipment was to be selected for subsequent reconstructions of the enterprise.
The criteria for assessing the quality of the steam traps were:
reliable performance indicators,
stable condensate drainage,
lack of passing steam,
The evaluation criteria for the pressure reducing valves were:
accuracy and stability of maintaining the secondary set pressure downstream of the valve,
ease of adjustment,
The entire line of Japanese float steam traps and pilot relief valves has been successfully tested over 2 years of operation. So, for example, measurements with an ultrasonic diagnostic device of the RT type showed that all steam traps showed an almost complete absence of passing steam, especially in comparison with the inverted cup models. Pilot pressure reducing valves have been distinguished due to their high accuracy and stability in maintaining the set pressure, even with rather large +/- 3 bar pressure surges to the valve. The only remark, rather a feature, of all products of Japanese manufacturers was the darkening of the color of silver heat-resistant paint at high temperatures of more than 220 C, although the paint and varnish coating reliably protects all products from external factors.
According to the results of testing the steam condensate equipment, the Japanese equipment, once again, confirmed the high quality of its products, and the engineers of OPEKS ENERGOSYSTEMY showed high professionalism and excellent knowledge of steam processes. Our company was deservedly chosen as the official supplier of steam traps and pressure reducing valves for the rest of the industrial enterprise systems.
OPEKS ENERGOSYSTEMY supplies steam-condensate fittings and automation of the following Japanese manufacturers, these are YOSHITAKE and TLV.
