Spiral steel pipe specification model weight table
As an important building material, spiral steel pipe is widely used in construction, chemical, petroleum, natural gas and other industries. When choosing spiral steel pipe, specification model and weight are very important reference factors. The following is a commonly used spiral steel pipe specification model weight table for reference:
Specification model|diameter (mm)|wall thickness (mm)|length (m))|theoretical weight (kg/m)
Spiral steel pipe S1080|1020|816-12|145.21
Spiral steel pipe S1200|1200|8|6-12|189.7
Spiral steel pipe S1400|1400|816-12|233.9
Spiral steel pipe S1600|1600|8|6-121278.21
As can be seen from the above table, the weight of spiral steel pipes of different specifications is also different. In actual purchase and use, you can choose the appropriate pipe according to actual needs and theoretical weight.
2. Implementation standards for spiral steel pipes
In the field of spiral steel pipes, common implementation standards include GB/T 9711, GB/T 3091, SYIT 5037, etc. Among them, GBIT 9711 is the standard for steel pipes for oil and gas industry transportation, which is suitable for steel pipes for transporting fluids such as oil and natural gas; GBIT 3091 is the standard for welded steel pipes for low-pressure fluid transportation, which is suitable for steel pipes for transporting low-pressure fluids such as water, gas, and air; SYIT 5037 is the standard for welded steel pipes for oil and gas industry, which is suitable for welded steel pipes for transporting fluids such as oil and natural gas.
3. Production process and quality control of spiral steel pipes
1. Raw material procurement
(1) Select high-quality steel billets: Select high-quality steel billets that meet national standards to fundamentally ensure the quality of spiral steel pipes
(2) Strict inspection: Strict quality inspection of incoming steel billets, including size, appearance, chemical composition, etc., to ensure that they meet production requirements
2. Production process
(1) Heating: Heat the steel billet to a predetermined temperature to ensure the plasticity and toughness of the steel
(2) Rolling: Use advanced rolling equipment and multiple rolling passes to gradually form the steel billet into a spiral steel pipe.
(3) Forming: Use professional forming technology to ensure the shape and size accuracy of the spiral steel pipe.
(4) Welding: Use advanced welding technology to ensure the weld quality of the spiral steel pipe.
