Product Introduction

One, Cold drawn seamless steel tube, as a steel pipe for hydraulic cylinders, offers the advantage of uniform wall thickness, allowing cylinder manufacturers to machine slots and threads for the inner bore based on the outer diameter, eliminating the need for turning processes. This method is convenient and quick, enhancing production efficiency. In developed countries in Europe and America, 80% of hydraulic cylinder cylinders are produced using the cold drawing process of steel tubes. With the advancement of our country's steel tube production technology, cold drawn steel tubes as the base material are fully capable of meeting the pressure-bearing requirements for hydraulic cylinders. Coupled with our company's涡探（eddy current) and ultrasonic non-destructive testing on finished products, we can confirm that the cold drawn steel tubes are absolutely reliable for use as cylinder cylinders. Pressure burst tests have reached 600 BAR with no internal or external leakage.
