Bright steel pipe is a refined steel pipe that is cold drawn or cold rolled. Bright seamless pipes must undergo non-oxidation bright heat treatment (NBK state), non-destructive testing, the inner wall of the steel pipe is brushed with special equipment and high-pressure flushing, anti-rust oil is applied to the steel pipe for anti-rust treatment, and both ends are capped for dust-proof treatment.
Bright steel structure
(1) The inner and outer walls of the steel pipe have high precision and high smoothness. After heat treatment, the steel pipe has no oxidation layer and the inner wall has high cleanliness. The steel pipe can withstand high pressure, does not deform during cold bending, and has no cracks when expanding or flattening.
(2) Steel pipe color: white with bright color, with high metallic luster.
Characteristics of bright steel pipes
(1)Because there is no oxide layer on the inner and outer walls of bright steel pipes, it can withstand high pressure without leakage, has high precision, high smoothness, no deformation during cold bending, no cracks in flaring and flattening, etc. Therefore, products mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders, can be seamless pipes or welded steel pipes.
(2)The promotion and application of precision seamless pipes can save steel, improve processing efficiency, reduce processing procedures or equipment investment, save costs and greatly save machining hours, and increase production volume and material utilization. At the same time, it is helpful to improve product quality, reduce costs and improve economic benefits, which is of great significance.
Surface quality of bright steel pipes
(1)The inner and outer surfaces of the bright tube are clean, free of oxide layers, cracks, folds, rolls, scars, separation layers and hair lines.
(2)The bright tube has internal and external surface conditions (such as scratches, bulges, grooves) corresponding to the manufacturing method and heat treatment method used, but its depth shall not exceed 0.02mm.
Bright steel pipe packaging and storage
The bright tube is coated with anti-rust oil, the two ends are plastic plugged to prevent dust, the inner layer is waterproof plastic film, and the outer layer is packed in a plastic woven bag or wooden box.
