| High Light | Electric-Fusion Welded Steel Tube ，Water Supply Welded Steel Tube ，ASTM A139 Grade B Steel Tube | ||
The ASTM A139 Grade B welded steel tube is an electric-fusion (arc)-welded steel pipe specifically designed for water supply applications. This grade of steel tube is widely used in various industries due to its excellent strength, durability, and corrosion resistance. In this article, we will explore the material, specification, chemical composition, mechanical properties, and applications of ASTM A139 Grade B welded steel tube.
The ASTM A139 Grade B welded steel tube is manufactured using high-quality carbon steel. Carbon steel is known for its exceptional strength and toughness, making it suitable for various demanding applications. The use of carbon steel ensures that the welded steel tube can withstand high pressure and provide long-lasting performance.
The ASTM A139 Grade B welded steel tube is manufactured in accordance with the specifications set by the American Society for Testing and Materials (ASTM). The standard specification for this grade of steel tube is ASTM A139/A139M. This specification covers electric-fusion (arc)-welded straight-seam or spiral-seam steel pipe for water supply applications.
The chemical composition of ASTM A139 Grade B welded steel tube is as follows:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.30 max |
| Manganese (Mn) | 1.20 max |
| Phosphorus (P) | 0.035 max |
| Sulfur (S) | 0.035 max |
The mechanical properties of ASTM A139 Grade B welded steel tube are as follows:
| Property | Value |
|---|---|
| Tensile Strength | 60,000 psi (415 MPa) min |
| Yield Strength | 35,000 psi (240 MPa) min |
| Elongation | 22% min |
| Hardness | HRB 60 max |
The ASTM A139 Grade B welded steel tube is primarily used for water supply applications. Its robust construction and corrosion resistance make it suitable for transporting water in various industries, including municipal water systems, industrial water supply, and irrigation systems. The welded steel tube's high strength and durability ensure reliable performance even under high-pressure conditions.
Additionally, the ASTM A139 Grade B welded steel tube finds application in other sectors such as construction, infrastructure, and oil and gas industries. It is commonly used for structural purposes, piling, and casing in deep foundation applications. The versatility of this steel tube makes it a preferred choice for many engineering projects.
