Accelerating the establishment of a water quota system for the pipe industry

China is a big steel country. The water consumption in the steel industry accounts for more than 10% of the industrial water consumption, ranking the third in the industrial industry and belonging to the high water consumption industry. In 2002, the state promulgated the national standard of "water intake quota, part 2, hollow section manufacturers", which was revised times in 2012. The promulgation of water intake quota has greatly promoted the progress of water-saving technology in the steel industry. Technological measures such as technology water-saving, recycling water and waste-water reuse have been adopted comprehensively, and the water consumption index has been steadily improved. Water withdrawal per ton of steel decreased from 8.71 cubic meters in 2005 to 3.12 cubic meters in 2017, and water reuse rate increased from 94.3 percent in 2005 to 97.83 percent in 2017.

However, the standard work of water quota is still lagging behind, especially for industrial water quota, there are many problems such as vague concept, non-standard method, imperfect system, which cannot adapt to the new situation of water resource management. In accordance with the requirements of strict water resources management and water efficiency management innovation system, it is necessary to strengthen the in-depth study of the relevant standard system. In order to better promote the water-saving work of steel pipe suppliers, it is necessary to establish a perfect water quota standard system for steel industry.

1.The water quota standard system for the steel industry is an effective measure to support the national water-saving action. The state implements strict water resources management and assessment system. The steel industry is a high water consumption industry, so it is necessary to establish a water-saving assessment system corresponding to this. 2. The steel industry water quota standard system provides the direction for the water-saving work of steel enterprises.In the case of extensive water use in China's steel industry of rectangular hollow section, China has implemented the water intake quota for steel joint enterprises for nearly 20 years, which plays an important role in promoting water saving and water efficiency in steel enterprises. However, as the iron and steel industry to raise the level of water-saving water, limitations of water-saving management becomes more and more obvious, which can't adapt to the demand of steel water completely, and steel enterprise production process and product water quota, need to increase the constraint conditions, from the aspects of process and product water leading the all-round fine iron and mild steel tube manufacturers carry out the water-saving work.
