No Welding Defects
Seamless pipes are free from welding joints. Welding joints are usually the vulnerable parts of pipes and are likely to have problems like cracks and pores. However, seamless pipes don't have such issues, thus enhancing their reliability and safety. They are extensively applied in industries like oil - gas transmission and aerospace where high safety is demanded.
High Strength
Composed of a single and uniformly - structured metal, seamless pipes possess high strength. They are capable of withstanding significant pressure and tensile forces. In high - pressure oil pipelines or mechanical parts under great stress, seamless pipes can function excellently. For instance, they can endure the great pressure in deep - sea oil drilling.
Corrosion Resistance
Seamless pipes can be manufactured with various materials such as carbon steel, alloy steel and stainless steel based on specific needs. This endows them with corrosion - resistant properties, enabling them to resist the corrosion of acids, alkalis, salts and the atmosphere. In the chemical industry, they are used to convey different corrosive chemical substances and have a long service life.
High Dimensional Precision
The production process of seamless pipes can guarantee high - dimensional accuracy, which can satisfy the precise application requirements in different industries. In precision machinery manufacturing, aerospace and other fields where strict dimensional accuracy is required, seamless pipes can be precisely matched with various devices and structures to ensure the normal operation and overall performance of the equipment.

Production Process
①The 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 pipe
straightening→finishing→inspection△ (non-destructive, physical and chemical, Taiwan inspection)→warehousing ②The main production
process of cold-rolled (drawn) seamless steel pipe: Billet preparation→pickling lubrication→cold rolling (drawing)→heat
treatment→straightening→finishing→inspections.
