The precision steel pipes produced are precision cold drawn seamless pipes through anaerobic tempering treatment to eliminate surface and internal stress, and then phosphating and rust prevention treatment. The product has high dimensional accuracy, good ductility, easy to process and bend into various required shapes without the tube section being reduced or flattened; the tube surface has high precision, after anaerobic tempering treatment, the surface hardness is moderate, and the inner hole is easy to be connected by clamping sleeves. And the surface can be installed directly without pickling and rust removal after phosphating antirust treatment. The specifications of the product are outer diameter (D) Φ4mm-76mm, wall thickness (S) 0.5mm-6.0mm, which can be customized according to customer requirements. The length is 6 meters (except for custom-made), and the delivery status is NBK (normalizing), GBK (annealing), BKS (stress relief annealing). The main materials used are ST35, ST37.4 (10#), ST45 (20#), ST55 (35#), ST52 (16Mn), etc.
Bright precision seamless steel pipes can be phosphated, colored zinc (yellow zinc), white zinc plated according to customer requirements, and the length is less than 6 meters.

Dongguan Debiao Steel Pipe Co., Ltd.-------1, DIN2391 high-precision bright seamless steel pipe adopts Baosteel's high-quality carbon steel material, after fine drawing, non-oxidizing bright heat treatment (NBK state), non-destructive testing, and steel pipe inner hole passing High-pressure washing and pickling, the inner and outer walls of the steel pipe are treated with rust-proof oil, and the two ends are sealed for dust-proof treatment. The produced steel pipe has high precision and good smoothness. The inner and outer walls of the steel pipe have no oxide layer. The steel pipe can withstand the high pressure of liquid flow, and the steel pipe is not deformed by cold bending, and can be flared and flattened without cracks. The mechanical properties can be bent at any angle without deformation. It is mainly used to prepare steel pipes in the oil circuit of hydraulic systems. It is also called hard piping in hydraulic systems. Precision steel pipes for automobiles can meet customers who require high precision, high smoothness, tensile strength, and high mechanical properties for steel pipes. 2. DIN2391 high-precision black phosphating steel pipe is based on DIN2391 high-precision bright seamless steel pipe, and the inner and outer walls of the bright precision steel pipe are phosphated with the phosphating agent dilution formula, and the inner and outer walls of the steel pipe form a black protective film to prevent the steel pipe from rusting. protection. The black phosphating steel pipe is shiny in black, with good color and strong anti-rust ability. High-precision black phosphating steel pipes are also mainly used for piping in hydraulic systems, and it is more ideal to use ferrule (steel pipe) joints. 3. DIN2391 high-precision precision galvanized steel pipe adopts high-precision bright seamless steel pipe to be electro-galvanized, and the inner and outer walls of the steel pipe are plated with yellow zinc (color zinc), white zinc, and passivated. The length of the galvanized steel pipe is within 6 meters. can.
