Seamless steel pipe is a steel pipe perforated from a whole round steel, and there is no weld on the surface, which is called seamless steel pipe.
A steel pipe without seams along the perimeter of its cross-section. According to different production methods, it is divided into Hot Rolled Pipe, Cold Rolled Pipe, Cold Drawn Pipe, extruded pipe, pipe jacking, etc., all of which have their own process regulations.
From the Process
The seamless tube is formed by rolling, heated with round steel, pierced, hot rolled, sizing and straightened.
The materials are ordinary and High Quality Carbon Structural Steel (Q215-A~Q275-A and 10~50 steel), Low Alloy Steel (09MnV, 16Mn, etc.), alloy steel, stainless acid-resistant steel, etc.
According to the use, it is divided into two categories: General Use (for water, gas pipelines and structural parts, mechanical parts) and Special (for boilers, geological exploration, bearings, acid resistance, etc.)

Application
1. For buildings, there are many pipelines at the bottom, groundwater extraction when building buildings, boiler hot water transportation, etc.
2. Machining, bearing sleeves, processing machinery parts, etc.
3. Electrical: gas transmission, water power generation fluid pipeline.
4. Anti-static pipes for wind power plants, etc.
Production Process
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 pipe straightening→finishing→inspection△ (non-destructive, physical and chemical, Taiwan inspection)→warehousing
