3.Welded pipe is completed by cold rolling system, high frequency welding, molding process etc. It ia a kind of seam steel pipe.
Seamless steel tube contains hot-rolled seamless pipe and cold drawn seamless tube. Hot rolled tube has process as forging, piercing, rolling, plastic, etc. Generally, large diameter and thick wall seamless tube adopts this form; Cold drawn tube is made of cold-drawn tube billet, forming, material strength is relatively low, smooth appearance both outside and internal. Small diameter and thin wall seamless tube adopt this process mostly.
