Product Description
Product Overview
Precision steel pipes are high-precision, high-brightness seamless tubes manufactured through cold drawing or cold rolling processes. These pipes feature dimensional accuracy within 0.2mm for both inner and outer diameters, offering excellent bending and torsional strength while maintaining lightweight properties.
Key Features
- High dimensional accuracy: ±0.2mm tolerance for inner/outer diameters
- Superior surface finish with smooth inner and outer surfaces
- Excellent mechanical properties including bending and torsional strength
- Lightweight construction for optimized performance
- Available in carbon steel, alloy steel, and stainless steel materials
- Custom dimensions available from 0.5mm to 200mm
Manufacturing Processes
Cold Drawing
The most common production method involving cold processing of hot-rolled steel pipes to achieve precise diameter and wall thickness specifications.
Cold Rolling
Cold processing of hot-rolled billets through multiple rolling and drawing passes to control steel pipe dimensions.
Cold Extrusion
Heating steel billets to appropriate temperatures then extruding through specialized dies to form hollow pipes with uniform wall thickness and high surface finish.
