Outstanding : Due to complete arts and crafts ,our production have super brightness and cleanness , inner bore is clean as well . Its very helpful for manufacturer who produce auto accessory and hydraulic equipment as oil tubes.

Mechanical properties:These tubes can be bent at any angel and bear the impact of high pressure,cold bending,flaring,flating,and tensile fore without cracks and breaks,oxidized residual substances on either inner or outer surfurce of tubes .Additionally,blockage to penumatic, hydraulic and oil routes shall never occur .The elongation rate and tensile strength are in high standard.

In addition:We are good at small specification tubes .
