After piling pipe rusty spiral wire brushes and other tools used primarily for steel surface sanding, cleaning and preheat coil can remove loose or warped oxide, rust, welding slag. Hand tools rust can reach Sa2 grade power tools rust Sa3 level can be achieved, if the coil firmly attached to the surface of the oxide scale, the effect is not ideal tools rust, anti-corrosion construction required to reach the depth of anchor pattern.
In traditional applications based on the new application has been added, which makes the usefulness of spiral steel pipe more fruitful, and also reduces the cost of the use of spiral pipe. Radio frequency sensors to provide 200 volts, 50 amps of electricity flowing through spiral pipe flow, experimental samples by induction heating effect.
Coil itself does not get hot, but the experimental samples will be significantly fever. In the heating temperature exceeds arc melting machine, radio frequency sensors will provide more control so that scientists can adjust the specific alloy composition ratio. Strong pressure spiral pipe, plastic, and easy welding and machining molding; generally low pressure liquid delivery spiral submerged arc welded spiral steel pipe (SY5037-83), using double-sided automatic submerged arc welding or welding into the legal system for water, gas, air and steam. Spiral steel pipe market demand both fast growth trend without chaos will not fundamentally changed. Spiral steel pipe market can keep chaos hub depends on the rapid development of changes in demand. Currently, the macroeconomic regulation and control by the policy level, the future will bring some market growth rate slows down.
