The ASTM A787 7 steel pipe is an electric resistance welded steel tube designed for use in the mechanical industry. This article provides important information about the material, specifications, key features, chemical composition, mechanical properties, steel grades, applications, and possible alternative grades of ASTM A787 7 steel pipes.
The ASTM A787 7 steel pipe is manufactured using electric resistance welding (ERW) techniques. It is produced from low carbon steel coils, ensuring high strength and durability. The diameter of the pipes typically ranges from 1/2 inch to 6 inches, with wall thicknesses varying between 0.065 and 0.1 inches.
The key features of ASTM A787 7 steel pipes include:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.05 - 0.18 |
| Manganese (Mn) | 0.30 - 0.60 |
| Phosphorus (P) | 0.040 (max) |
| Sulfur (S) | 0.050 (max) |
| Property | Value |
|---|---|
| Yield Strength (MPa) | 215 (min) |
| Tensile Strength (MPa) | 380 (min) |
| Elongation (%) | 25 (min) |
| Hardness (HRB) | 70 (max) |
ASTM A787 7 steel pipes are designated by the steel grade followed by a numerical value that indicates the yield strength. For example, ASTM A787 7 Grade 215 refers to a pipe with a minimum yield strength of 215 MPa.
Due to their excellent strength and durability, ASTM A787 7 steel pipes find applications in various mechanical fields including:
While ASTM A787 7 steel pipes offer exceptional performance, there are alternative grades available for different applications. These include ASTM A500, ASTM A513, and ASTM A519, which may have different material compositions, mechanical properties, or dimensions. Considering the specific requirements of your project is crucial in selecting the appropriate alternative grade.
