Spiral pipe conveying fluid can be in accordance with seasonal changes, to take reasonable on and off cooling tower operating fan and pump room used to cool the work of the axial fan measures, effectively reducing the electricity consumption. In due to the steelmaking system, continuous casting system has special requirements for the supply of water medium, especially when smelting high-quality steel, the control of the temperature difference of the water medium plays a vital role in stabilizing product quality and the development of new steel grades.

 Spiral Pipe

In addition, the outdoor temperature changes can be used to reasonably start and stop the fan to achieve the purpose of reducing electricity consumption and saving energy. Take the initiative to get in touch with each production line user point to understand the specific requirements of the water temperature and determine the most reasonable range to meet the needs of production while achieving the purpose of reducing costs and increasing efficiency. Making full use of the characteristics of seasonal changes and lower outdoor temperatures at night, we take the method of real-time tracking and detection of the change in the temperature of the water medium by the personnel on duty at the production site to make timely adjustments to the operating fans and reduce the number of fans running as far as possible. Since a week, the number of running fans has been reduced by half, and electricity consumption has been similarly reduced by half.

1. Spiral pipe characteristics

Straight seam welded pipe production process is simple, high production efficiency, low cost, the development of faster. The strength of spiral welded pipe is generally higher than the straight seam welded pipe, can use a narrower billet to produce a larger diameter welded pipe, but also with the same width of the billet to produce a different diameter welded pipe. However, compared with the same length of straight seam pipe, the length of the welded seam increases by 30 to 100%, and the production speed is lower. Therefore, most of the smaller diameter welded pipes are straight seam welded, and most of the large diameter welded pipes are spiral welded.

2. Spiral pipe and its standard classification

Spiral submerged arc welded steel pipe for the transmission of fluids under pressure (SY5036-83) is mainly used for the transmission of oil and gas pipelines; spiral high-frequency welded steel pipe for the transmission of fluids under pressure (SY5038-83), welded with high-frequency lap welding method, spiral high-frequency welded steel pipe for the transmission of fluids under pressure. Steel pipe pressure-bearing capacity, good plasticity, easy to weld and process forming; general low-pressure fluid transmission with spiral submerged arc welding steel pipe (SY5037-83), using double-sided automatic submerged arc welding or single-sided welding method for water, gas, air and steam and other general low-pressure fluid transmission with submerged arc welding steel pipe.

Now the common standards for spiral pipe are generally divided into: SY/T5037-2000 (Ministry standard, also known as ordinary fluid transmission pipeline with spiral submerged arc welded steel pipe), GB/T9711.1-1997 (national standard, also known as the first part of the technical conditions for the delivery of steel pipes for the oil and gas industry: Class A steel pipe (to the current strict requirements of GB/T9711.2 Class B steel pipe)), API-5L (American Petroleum Institute). API-5L (American Petroleum Institute, also known as pipeline steel pipe; which is divided into PSL1 and PSL2 two levels), SY/T5040-92 (spiral submerged arc welded steel pipe for piles).
