ASTM A179 is a seamless cold drawn low carbon steel pipe made through a cold drawing process. Its chemical components are carbon (C), manganese (Mn), phosphorus (P), sulfur (S) and other elements. The content of these elements has an important impact on the mechanical properties and high temperature resistance of pipes.
ASTM A179 steel pipes have various specifications. According to different usage occasions and equipment requirements, steel pipes with different diameters and wall thicknesses can be selected. The seamless steel pipe has an outer diameter of 19.05 inches and a wall thickness of 2.11 inches.
ASTM A179 cold drawn low carbon steel pipe needs to go through multiple processes during the manufacturing process, such as billet preparation, rolling, straightening, heat treatment, pickling, inspection, etc. These processes ensure the dimensional accuracy, surface quality, mechanical properties and metallographic structure requirements of the steel pipe.
In summary, ASTM A179 carbon steel pipe is a high-quality, high-performance steel pipe material that is widely used in the manufacture of high-voltage equipment. Its advantages of high strength, high pressure resistance and corrosion resistance ensure the safety and stability of the equipment.

Basic concepts of cold drawn steel pipes
Cold drawn steel pipe is a steel pipe made through precision cold drawing process. It has the characteristics of high precision, high strength, light weight, corrosion resistance and easy processing. Compared with ordinary steel pipes, the production process of cold-drawn steel pipes is more complex and requires higher precision and quality control, so its price is relatively high.
Cold drawn steel pipe production process flow
1. Smelting and continuous casting
The first step in producing cold drawn steel pipes is smelting and continuous casting.
2. Blank straightening and deburring
The surface of the billet after continuous casting often has various defects such as cracks, folds, and rust, which require straightening and deburring.
3. Cold drawing processing
The straightened and deburred blank can be cold drawn. Cold drawing processing is a process of compressing and stretching the blank through a special mold, which can gradually process the blank into a finished tube of required specifications and shapes.
4. Heat treatment and tempering
Cold drawn steel pipes require heat treatment and quenching and tempering.
5. Testing and Inspection
The final step is testing and inspection. The inspection mainly includes appearance inspection and performance inspection.
