"With a diameter of 2.86 meters, family cars can easily pass by. This is the first time we have produced and processed such a' super-large-diameter' slide valve". On November 22, Ma Xiaocheng, the production and operation center of PetroChina Bohai Equipment Petrochemical Equipment Company, said that the world's largest diameter double-acting slide valve processed and produced by the company has entered the flange plane processing process.
Bohai Equipment Petrochemical Equipment Company is producing the world's largest diameter double-acting slide valve.
It is reported that this DYLS2860 double-acting slide valve body was "tailored" by Bohai Equipment Petrochemical Equipment Company for users of Shandong refining and chemical enterprises. Because of its large diameter and volume, it brings many problems to the process of product hoisting, clamping and alignment, and the height and diameter of valve body are beyond the processing range of all lathes in the company.
"The construction period must be guaranteed and the quality must be guaranteed". In order to fulfill the promise made to users, petrochemical equipment company organized production backbones, technical experts and machine tool operators to tackle key problems in groups. Facing this valve body, which is much larger than a large horizontal lathe, the research team first considered using a vertical lathe to process it, but the diameter was too large for the large vertical lathe to process it. Everyone set their eyes on the CNC boring and milling center. After field measurement, the CNC boring and milling center can not only meet the height requirements, but also avoid the problem of rotary diameter, and give full play to the equipment capacity flexibly, thus successfully solving the production problems by "boring instead of turning".
Slide valve is the key equipment of FCC unit in refinery, which is used to control the pressure of regenerator or the pressure difference between regenerator and reactor. Failure will cause shutdown of the unit. In the process of product research and development for many years, Bohai Equipment Petrochemical Equipment Company has formed a long-term and highly reliable design concept, established a strict product quality management system, and its products have spread all over large petrochemical and refining enterprises in China, becoming the industry leader of similar products in China. The slide valve products designed and produced by this company meet ASME (american society of mechanical engineers) standards are also exported to Russian market.
