The Role of Cast Steel Gate Valves in Urban Development and Construction
1. The urban construction system usually uses a large number of low-pressure cast steel gate valves and the development of environmental protection and energy conservation. The low pressure of using iron gate valves gradually turns to green plastic sheet valves, sanitary grade pipe fittings, transition metal sealing butterfly valves and line sealing butterfly valves. The pipeline for the development of oil and gas projects requires a large number of planar gate valves and ball valves.
2. The other side of energy development is energy saving, so from the perspective of energy conservation, development of steam traps, and high development of subcritical and supercritical parameters.
3. The large-scale development of power station construction requires large-caliber, high-pressure relief valves and pressure reducing valves, as well as the need to quickly open and close valves.
4. The needs of the package engineering, supply valve through a single species species and specifications. Valve manufacturers need to provide a valve project all the increasing trend.
The above is a detailed introduction of the role of cast steel gate valves in urban development and construction. If you have any questions about cast steel gate valves , prices, models, and pictures, please contact us for new information on cast steel gate valves.
Finned tube heat exchanger is one of the earliest and most successful discoveries in the process of improving tube heat exchanger. Up to now, this method is still the most widely used one among all kinds of heat transfer enhancement methods for tubular heat exchange surfaces. It is not only suitable for single-phase liquid flow, but also has great value for phase change heat transfer. However, before the 1960s, ordinary finned tube heat exchangers mostly used flat fins without any treatment on the surface structure. This type of fin has no other function of enhancing heat transfer except increasing the heat transfer area to achieve the effect of enhancing heat transfer. With the development of air cooling technology and the increasing trend of using gas medium in heat exchanger, finned tube heat exchanger has been paid more and more attention. Especially since the Sergles report on enhanced heat transfer was published at the Sixth International Conference on Heat Transfer, a large number of highly efficient fin surface structures have been developed continuously. At present, most of the finned tube heat exchangers used for live and clean gas use a new and efficient fin surface structure, which has achieved significant enhanced transfer effect.
