I'll answer; Seamless steel pipe with extra-large hydraulic cylinder refers to seamless steel pipe with diameter greater than 219mm and wall thickness not less than 2mm, which is widely used in high-pressure liquid transportation and hydraulic system in industrial and aviation fields. This kind of specially processed seamless steel pipe needs high strength, high wear resistance and corrosion resistance, so its manufacturing material is generally high-quality carbon structural steel or alloy structural steel. Before steel pipe processing, it is necessary to treat the blank and then shape the steel pipe. The surface of steel pipe needs mirror polishing, pickling and phosphating to ensure its surface flatness and smoothness. At the same time, in order to ensure that there are no air holes and foreign bodies in the steel pipe, the manufacturer also needs to detect the possible defects in the steel pipe through ultrasonic flaw detection. ?
when installing seamless steel pipes for extra-large hydraulic cylinders, it is necessary to operate in strict accordance with relevant technical standards to avoid potential safety hazards such as oil leakage caused by excessive fatigue. At the same time, it is also very important to overhaul and maintain the oil cylinder regularly. Seamless steel pipe with extra-large hydraulic cylinder is an important transportation pipeline in industrial and aviation fields, and its quality and safety have great influence on the use effect and personal safety. Therefore, it is necessary to pay special attention to and follow the relevant standards and specifications when selecting and using.
