According to the use performance, X-ray machines can be divided into directional X-ray machines, circumferential X-ray machines and pipeline crawlers. The directional X-ray machine is the most widely used X-ray machine, and its head produces a cone angle with an X-ray direction of about 40 degrees. The X-rays produced by the circumferential X-ray machine radiate to 360 degrees, mainly used for shooting large diameter pipes and circumferential welds. The crawler is an X-ray machine installed on the crawler device designed to solve the problem of shooting the circumferential weld of long pipes.
DEAR Air Separation has stepped forward on the road of energy-saving air separation, and the road is getting wider and wider. After 11000 grade energy-saving air separation has been successfully put into the market and achieved good results, Deere Design and Research Institute has launched the design and development of 30000 grade energy-saving air separation. The main feature of 30000 grade air separation is high energy consumption, which makes it reduce energy consumption. It is a new challenge for designers. Through many research and development experiments, Deere Design and Research Institute boldly adopted various methods such as changing the gas processing capacity, increasing the equipment barrel diameter, and designing energy-saving multi-layer main cooling. Through the application of a number of energy-saving technologies, it successfully achieved the test scheme of 30000 grade air separation energy consumption reduction, And apply it widely.
