National standard spiral steel pipes, commonly known as 9711.1 and 9711.2 spiral steel pipes, are widely used in various industrial applications. These pipes are manufactured using different materials such as 16Mn, Q345B, L245, L360, and even high-grade X40 to X80. They are primarily used for transporting wastewater, purified water, and in water treatment plants, power stations, chemical industries, and even nuclear facilities. Additionally, they are suitable for conveying both flammable and non-flammable fluids. In addition to the national standards, these pipes also meet industry specifications like API SPEC 5L, EN10217, and SY/T5037. The production process involves hot-rolled steel strips that are welded using a constant temperature spiral forming and automatic submerged arc welding technique, ensuring high-quality and durable products for oil and gas transportation.
When working with steel products, it's essential to understand the weight calculation formulas for different shapes and types of steel. Here are some key formulas:
1. Weight of round steel per meter = 0.00617 × diameter × diameter
2. Weight of spiral steel pipe per meter = (diameter - wall thickness) × wall thickness × 0.02466
3. Weight of square steel per meter = 0.00786 × side width × side width
4. Weight of hexagonal steel per meter = 0.0068 × opposite side diameter × opposite side diameter
5. Weight of octagonal steel per meter = 0.0065 × diameter × diameter
6. Weight of rebar per meter = 0.00617 × diameter × diameter
7. Weight of equal angle steel per meter = side width × side thickness × 0.015
8. Weight of flat steel per meter = 0.00785 × thickness × width
9. Weight of seamless steel pipe per meter = 0.02466 × wall thickness × (outer diameter - wall thickness)
10. Weight of electric welded steel pipe per meter = same as seamless steel pipe
11. Weight of steel plate per square meter = 7.85 × thickness
12. Weight of brass tube per meter = 0.02670 × wall thickness × (outer diameter - wall thickness)
13. Weight of copper tube per meter = 0.02796 × wall thickness × (outer diameter - wall thickness)
14. Weight of aluminum tread plate per square meter = 2.96 × thickness
15. Specific gravity of non-ferrous metals: copper plate 8.9, brass plate 8.5, zinc plate 7.2, lead plate 11.37
16. Weight of non-ferrous metal sheet per square meter = specific gravity × thickness
17. Weight of square tube per meter = (side length + side length) × 2 × thickness × 0.00785
18. Weight of unequal angle steel per meter = 0.00785 × edge thickness × (long side width + short side width - edge thickness)
19. Weight of I-beam per meter = 0.00785 × waist thickness × [height + f (leg width - waist thickness)]
20. Weight of channel steel per meter = 0.00785 × waist thickness × [height + e (leg width - waist thickness)]
