ASTM A795 Standard
ASTM A795 steel pipe is mainly used in low-pressure and medium-pressure fluid transmission systems, especially fire protection systems. This standard covers black and hot-dip galvanized welded steel pipes and is suitable for steel pipes with diameters ranging from 1/2 inch to 10 inches.

The mechanical properties of the steel pipe must meet the following requirements:
Tensile strength | Yield strength | Elongation( % ) |
48,000 psi (330 MPa) | 30,000 psi (205 MPa) | 23% |
Surface treatment
Hot-dip galvanized steel pipes must be galvanized to enhance their anti-corrosion properties. The thickness of the galvanized layer should meet the standard requirements to ensure the long-term service life of the steel pipe in a humid or corrosive environment.
