China Drying Network News Yueyang Zhuosheng Valve Pipeline Co., Ltd. adopts independent large-diameter high-pressure pipe push-pull cold bending process and equipment. The diameter of 610 mm, thickness of 60 mm, bending radius is 3 times the diameter of 304H stainless steel 12Cr2MoG high-pressure alloy The steel pipe has recently been successfully used in China Coal Ordos Energy Chemical Co., Ltd. China Coal Tucker Fertilizer Project 1 million tons/year ammonia plant project. It is reported that the diameter and wall thickness of the high-pressure alloy steel pipe are the highest in the country. It is understood that the traditional mid-frequency hot bend manufacturing process consumes large amounts of energy and there are certain potential safety hazards such as radiation pollution. Yueyang Zhu Sheng Company designed and manufactured a push-pull type cold bending machine based on the defects and deficiencies of the traditional process. The device is pushed and pulled at the same time during the cold bending and bending. In practice, the welding seam can be reduced by more than 80% compared with the conventional design, and the construction period is shortened by about 50%. This saves time for the enterprise, reduces the cost and improves the construction. quality. At present, the use of this new process to equip curved pipes has been applied in more than 40 petroleum, chemical and electric power companies such as Shanxi Tianze Coal Chemical Co., Ltd. In another development, the process device has passed the Hunan Provincial New Product (New Technology) appraisal, and won the first prize for the scientific and technological innovation of the China Construction Enterprise Management Association and the second prize for the scientific and technological progress of Yueyang City. 8Ton Crawler Excavator,Huina Crawler Excavator 1580,Wheel Crawler Excavator 8Ton,Mini 8Ton Crawler Excavator SHANDONG KEN STONE HEAVY MACHINERY CO.,LTD , https://www.chinaexcavator.com
