In 2008, it was rated as "National New Product". Now it is mainly used in industrial enterprises in chemical, petroleum and other industries.

5. ESH28-65 automatic closing fixed fulcrum lever bucket type high-pressure steam trap

The core technology of the product has reached the leading level in China, improving the defect that the working pressure of the same type of steam trap is greater than 4.5MPa.G or less than 0.05MPa.G, and can work reliably in the industrial steam pipeline network with a working pressure difference of 0.01MPa.G~6.5MPa.G, which meets the needs of eliminating condensate and non-condensable gas and preventing steam leakage, which is conducive to the recovery and reuse of condensate. In 2008, it was rated as "National New Product". Now it is widely used by major projects such as petroleum and petrochemical in China and related enterprises.

6. TB82-150 type temperature control high-pressure round plate bimetal plate trap

The product is one of the representatives of the high parameters of the "Hongfeng" series of traps, using the domestic leading positive sealing round plate bimetal disc valve body structure with adjustable drainage temperature, the working pressure difference can reach 2.0MPa~15.0MPa, and the drainage temperature adjustment range is up to 100°C~340°C, which has significant energy-saving and environmental protection functions, and is mainly used in steam systems with high requirements for temperature, pressure and safety. In 2012, it was selected for the air-conditioning system of the expansion project of the National Museum.

7. QTSS43H-3-100B high-pressure single-pilot natural gas trap

The product is a special valve for high-pressure natural gas developed by the company with domestic advanced level, which adopts the innovative design of one-way segmentation cavity and double float single guide, with high parameters such as nominal pressure, working pressure and displacement, which can purify the natural gas wellhead and effectively separate impurities. The effect of energy saving and environmental protection is obvious, and the application prospect is very broad.

8. HP series condensate recovery device

The device is one of the large-scale equipment for steam condensate recovery developed by the company, which is an energy-saving product that effectively uses hot condensate and reduces waste, and is of great significance to the creation of energy-saving and environmentally friendly enterprises and the promotion of energy-saving and emission reduction. The unit uses gas as a power to automatically transport hot condensate from a lower position to a higher location for repeated recovery and recycling. In 2003 and 2004, it was continuously rated as "Gansu Province Excellent New Product and New Technology", and in 2007, it was rated as "Gansu Famous Brand Product". It is widely used in petroleum, chemical, pharmaceutical and other large enterprises and major projects.

9. HDP series condensate closed recovery device

The device uses one high-speed fluid to transport another fluid through a multi-channel collector, which solves the problem of condensate recovery at different pressures. The device adopts PLC intelligent automatic control system, which can not only operate independently, but also communicate with industrial Ethernet and DCS control center through data communication bus to achieve digital distributed control, and is an automatic energy-saving device for recycling a large number of high-temperature condensate. In 2008, it was rated as "Gansu Province Excellent Product of Technological Innovation".
