ASTM A179 Pipe

Key Characteristics of ASTM A179 Pipe

1. 1.Material Composition:
2. - ASTM A179 pipes are made primarily from low carbon steel, with a carbon content typically less than 0.08%. This low carbon content contributes to good weldability and ductility.
3. 2. Mechanical Properties:
4. - The pipes exhibit good mechanical properties, including:
5. - Tensile strength: Minimum 55,000 psi
6. - Yield strength: Minimum 30,000 psi
7. - Elongation: Minimum of 30% in 8 inches
8. 3. Manufacturing Process:
9. - The pipes are produced through a seamless process, meaning they do not have a welded seam. The cold-drawing process gives the pipe higher strength and improved surface finish.
10. 4. Dimensions:
11. - The pipe is available in various sizes and wall thicknesses. It typically ranges from 1/2 inch to 4 inches in nominal diameter, though sizes may vary based on application requirements.
12. 5. Finishes:
13. - ASTM A179 pipes can be supplied in various finishes, including:
14. - Bright annealed - Oiled - Pickled (to remove scale)
