Precision Seamless Steel Pipe is a high-precision tubular product manufactured through cold drawing or cold rolling processes,featuring extremely tight dimensional tolerances,smooth inner and outer surfaces,and excellent mechanical properties.It is produced from high-quality carbon steel and alloy steel billets without welding seams,ensuring uniform structure and reliable performance under pressure.
Key Features
Ultra-high precision:Outer diameter and wall thickness tolerance can reach±0.01 mm,roundness and straightness are strictly controlled.
Smooth surface:Bright and clean inner/outer surface,no scale,no cracks,effectively reducing fluid resistance.
High dimensional stability:Small deformation,good concentricity,suitable for high-precision assembly.
Excellent mechanical properties:High tensile strength,good toughness,fatigue resistance and pressure resistance.
No weld defects:Seamless structure ensures no leakage risk and uniform stress distribution.
