Wanlihong Precision Hydraulic Seamless Steel Tube Knowledge Introduction - Shandong Seamless Steel Tube Factory provides hydraulic steel tubes used mainly stainless steel seamless tubes and ordinary seamless steel tubes, although stainless steel seamless tube has superior mechanical properties, but due to the high price The accuracy is low and has not been universally used. Although common seamless steel tubes are commonly used, they have poor mechanical properties and low precision. Before they are used, they usually go through a series of welding, test equipment, pickling, caustic washing, water washing, long-term oil-shaking, and leak testing. Complex, time-consuming, unreliable materials, and failure to completely remove pipe residue have become a major risk for the entire hydraulic system to fail at any time. According to statistics, 70% of failures in hydraulic systems are caused by this reason. This information is provided by Shandong Wanlihong Seamless Steel Tube Factory.
