Wholesale Price Seamless Pipe - 20 # Precision Steel Pipe – JINBAICHENG Detail:
Product Usage
Automobiles, machine parts, etc. have high requirements on the precision and finish of steel pipes. The current users of 20# precision steel pipes are not only users who require relatively high precision and smoothness. Because the precision of the precision bright tube is high, the tolerance can be maintained at 2–8 wire, so many machining users in order to save labor, material, and time. The loss of seamless steel pipes or round steel is slowly turning into precision bright pipes.
