Advantage of Precision Seamless Steel Tubes
2. High precision can be done in small batch production;
3. Cold drawing finished products with high precision and good surface quality.
4. The transverse area of the steel tube is more complicated;
5. Steel pipe performance is superior, metal is more dense.
