What is ASTM A795 ERW pipe
ASTM A795 ERW pipe is an electric resistance welded pipe produced in accordance with the standards of the American Society for Testing and Materials (ASTM International).
ASTM A795 ERW pipe is usually made of low carbon steel with good weldability and corrosion resistance. According to different usage requirements, the pipe can be galvanized to enhance its corrosion resistance. The following are common specifications of ASTM A795 ERW pipe:
Specification | Inch | mm | Wall Thickness | Wall thickness | Tension strength | Yield Strength |
1/2 | 0.84 | 21.34 | 0.109 | 2.77 | ≥48,000 psi | ≥30,000 psi |
3/4 | 1.05 | 26.67 | 0.113 | 2.87 | ≥48,000 psi | ≥30,000 psi |
1 | 1.315 | 33.4 | 0.133 | 3.38 | ≥48,000 psi | ≥30,000 psi |
1 1/4 | 1.66 | 42.16 | 0.14 | 3.56 | ≥48,000 psi | ≥30,000 psi |
1 1/2 | 1.9 | 48.26 | 0.145 | 3.68 | ≥48,000 psi | ≥30,000 psi |
2 | 2.375 | 60.33 | 0.154 | 3.91 | ≥48,000 psi | ≥30,000 psi |
ERW process is an efficient and precise welding method that heats steel with high-frequency current and applies pressure to form a high-strength pipe with smooth welds. This gives ASTM A795 pipe the following advantages:
1. High strength: ensure the stability and safety of the pipe under high pressure.
2. Smooth weld: reduce welding defects and improve pipeline reliability.
3. Cost-effectiveness: Compared with other welding methods, ERW process is more economical and practical.
