Abstract
The utility model relates to the technical field of cold-drawn steel tubes in metallurgical industry, in particular to a hexagonal socket cold-drawn precision steel tube which comprises a steel tube body. The inner wall of the steel tube body is hexagonal. The inner wall of the steel tube body is covered by a polished layer. The outer wall of the steel tube body is coated by a polyethylene anticorrosion layer. The hexagonal socket cold-drawn precision steel tube is novel in structure and meets requirements of diversified market. The polyethylene anticorrosion layer is coated to the outer wall of the cold-drawn steel tube, so that better corrosion resistance is achieved and the service life of the steel tube is prolonged.
