The EN 10305-4 standard was developed in Europe and mainly involves high-precision, high-quality seamless cold-formed tubes, especially seamless steel tubes for hydraulic and pneumatic systems.
EN 10305-4 seamless cold-drawn steel tubes are available in a variety of specifications with a wide range of outer diameters, from 4mm to larger sizes. The inner wall of the steel tube is brushed and high-pressure washed with special equipment to ensure high cleanliness of the inner wall. The surface of the steel tube is treated with anti-rust oil and sealed at both ends to prevent dust from rusting and contamination. EN 10305-4 precision steel tubes are widely used in hydraulic systems, automobile manufacturing, machinery manufacturing, petrochemicals and other fields.
