Zhengde the seamless rectangular tube is a long strip of steel with
a hollow section and no seams around it. The use of rectangular
seamless steel pipes to manufacture ring parts can improve material
utilization, simplify manufacturing processes, save materials and

etc., which have been widely used in steel pipes. Steel pipe is
also an indispensable material for various conventional weapons,
and barrels, barrels, etc. must be made of steel pipes. Steel pipes
