Spiral steel pipe in the traditional applications based on the new application has been added, which makes the usefulness of spiral steel pipe more rich, and also reduces the cost of using the spiral pipe. Radio frequency sensors to provide 200 volts, 50 amps of current through the spiral steel pipe, experimental samples by induction heating effect. The coil itself does not get hot, but the experimental samples will be significant fever. In the heating temperature exceeds arc melting machine, radio frequency sensors will provide more control so that scientists can adjust the composition ratio of alloy detailed.
Radio frequency sensor spiral steel pipe in a matter of seconds on the experimental sample heating 800-1000 degrees Celsius, the goal of this process is below the melting point of the sample heating, the sample atoms to form a specific part of the crystal structure. This is reinforced in the crystal structure established under the dendrite breakthrough technology.
Using double-sided spiral submerged arc spiral pipe welding technology, the narrowband (board) volume continuous welded steel pipe. In our natural gas and other long-distance gas pipeline project has been widely used, is our long-distance gas pipeline project using the main tube. Spiral steel pipes are widely used in natural gas, petroleum, chemical, electric power, heat, water, steam heating, hydropower penstock, construction piling pipe, power generation, water and other long-distance pipelines and piling, dredging, bridges, steel, etc. engineering fields.
