Transmission Line Steel Tubular Tower Our steel poles are made from quality sheet through bending,
forming, automatic welding and hot galvanization. We can reach one-run
machining length of 14m and can bend sheet of thickness up to 45mm. We
adopt advanced welding procedures, automatically weld main joints and
reach rank-II welding quality. We
have got 500kV Transmission Line Tubular Tower Quality Certificate from Power
Industry Steel Tower Qualified Inspection & Test Center from 2009
year.

It is understood that the company used a pressure swing adsorption (PSA) decarburization and ammonia synthesis raw hydrogen extraction technology in the conversion of ammonia plants, and added new devices such as air separation, pressure swing adsorption, and hydrogen sulfide, and transformed the gas conversion equipment. , Liquid nitrogen cleaning equipment, conversion equipment and synthetic compressors and other key components. Compared with traditional low-temperature methanol wash or liquid nitrogen wash, PSA is a dry purification process that does not require supplemental cooling. Due to the adoption of the pure oxygen two-stage conversion technology, the load of the first stage furnace is shared, and the heat transfer is converted into adiabatic conversion, thereby saving the first stage process steam and fuel, greatly improving the thermal energy utilization rate and saving energy. At the same time, the methane content in the gas at the conversion conversion section is greatly reduced, which can save energy and reduce methane gas circulation. The device also improves compressor efficiency and turbine expansion efficiency, reduces steam consumption, increases ammonia net value, reduces system resistance, and reduces compressor energy consumption. In addition, the device also uses a heat pipe technology, so that the recovery furnace exhaust fumes waste heat recovery more fully, the use of synthetic ammonia reaction waste heat heating boiler feed water, reducing fuel consumption; use of efficient tray technology transformation of methanol washing device tower internals, without adding equipment Under the premise of quantity, the system capacity has been increased by 50%.
Tianji Synthetic Ammonia Transforms Energy Saving and Production Increase
Tianji Group recently reconstructed the ammonia plant and expanded its annual production capacity from 300,000 tons to 450,000 tons. Meanwhile, the comprehensive energy consumption per ton of ammonia dropped from 2.29 tons of standard coal to 1.89 tons. Tianji Group has thus become a leader in energy conservation in the coal chemical industry.
