ASTM 304 High Pressure Steel Pipe is a long hollow Steel Pipe with no joints on its periphery. The thicker the wall thickness of seamless pipe is. The more economical and practical, the thinner the wall thickness, and the higher the processing cost. Secondly, the production process of the product determines its limited performance. Generally, the accuracy of ASTM 304 High Pressure Steel Pipe is low. Uneven wall thickness. The brightness inside and outside the pipe is low, the sizing cost is high, and there are pits and black spots inside and outside the pipe, which are not easy to remove: its detection and molding must be processed online. Therefore, it has its advantages in high pressure, high strength and mechanical structure materials
ASTM 304 High Pressure Steel Pipe is widely used in fluid transmission pipeline, boiler plant and engineering machinery processing plant. General Seamless Steel Pipe is rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output. They are mainly used as pipes or structural members for conveying fluid

Production Process:
1. The main production process of hot-rolled seamless steel pipe (main inspection process):
Tube blank preparation and inspection→tube blank heating→piercing→tube rolling→steel reheating→fixed (reduced) diameter→heat treatment △→finished tube straightening→finishing→inspection (non-destructive, physical and chemical, Taiwan inspection)→warehousing
2. The main production process of cold-rolled (drawn) Seamless Steel Pipes:
Billet preparation→pickling lubrication→cold rolling (drawing)→heat treatment→straightening→finishing→inspection
