Introduction to the applications and uses of the material of National Standard 9711.1 spiral steel pipes.
2014-07-23
The national standard spiral steel pipe is referred to as 9711.1 spiral steel pipe, 9711.2 spiral steel pipe, material classification: 16Mn material spiral steel pipe, Q345B spiral steel pipe, L245 spiral steel pipe, L360 spiral steel pipe, X40-X80 spiral steel pipe. Main uses include sewage treatment spiral steel pipes, water purification spiral steel pipes, water plant spiral steel pipes, power plant chemical enterprise spiral steel pipes, nuclear power spiral steel pipes, and spiral steel pipes for transporting flammable and non-flammable fluids. The national standard spiral steel pipe and the petroleum department standard SY/T5037 spiral steel pipe are made from hot-rolled strip as raw material, formed by ambient temperature spiraling and welded using automatic submerged arc welding technology. The product complies with standards APISPEC5L, EN10217, GB/T9711.1, GB/T9711.2. It is mainly used for transporting flammable and non-flammable fluids in the petroleum and natural gas industries as well as for structural purposes.
Theoretical calculation formulas for spiral steel pipes and various types of steel.
Steel calculation formula 1: Weight of round bar per meter = 0.00617 × diameter × diameter.
Weight of spiral steel pipe per meter = (diameter - wall thickness) × wall thickness × 0.02466.
2: Weight of square bar per meter = 0.00786 × edge width × edge width.
3: Weight of hexagonal bar per meter = 0.0068 × opposite side diameter × opposite side diameter.
4: Weight of octagonal bar per meter = 0.0065 × diameter × diameter.
5: Weight of rebar per meter = 0.00617 × diameter × diameter.
6: Weight of equal angle iron per meter = edge width × edge thickness × 0.015.
7: Weight of flat iron per meter = 0.00785 × thickness × width.
8: Weight of seamless pipe per meter = 0.02466 × wall thickness × (outer diameter - wall thickness).
9: Weight of electric welded pipe per meter = weight of seamless pipe.
10: Weight of plate per square meter = 7.85 × thickness.
11: Brass tube: weight per meter = 0.02670 * wall thickness * (outer diameter - wall thickness).
12: Copper tube: weight per meter = 0.02796 * wall thickness * (outer diameter - wall thickness).
13: Aluminum checker plate: weight per square meter = 2.96 * thickness.
14: Specific gravity of non-ferrous metals: Copper plate is 8.9, brass plate is 8.5, zinc plate is 7.2, lead plate is 11.37.
15: The calculation formula for non-ferrous metal plates is: weight per square meter = specific gravity * thickness.
(Square tube) weight per meter = (side length + side length) ×2×thickness×0.00785.
Weight of unequal angle iron per meter=0.00785×edge thickness(long edge width+short edge width--edge thickness).
Weight of I-beam per meter=0.00785×waist thick[height+f(leg width-waist thick)].
Weight of channel iron per meter=0.00785×waist thick[height+e(leg width-waist thick)].
