In general, pressure vessel mainly consists of shell, heads, flanges, potted elements, opening tubing connection and supports, also equipped with safety feature, meters and other components that finish all kinds of processing, which is widely used in all sectors of the national economy, Petroleum Chemical Industry, Energy Industry, Technology, and so on. It is almost 30 years since we began to work on it, now have archived independently capacity for designing and manufacturing, also with full set of inspection equipment. With the development of improving processing, we have overcome the features of uneven pressure, large temperature deviation, etc, got the certificate for Class and Pressure Vessel. We can manufacture all kinds of Pressure Vessels according to different requirements,for example, reactor, cleaner, heat exchanger, submarine oxygen tank(less than 99.8kg), etc. All the products meet international standard in quality. At present, we have established and kept long-term cooperation relationship with many domestic and foreign large enterprises.
