Rust treatment of Spiral steel pipe

Spiral steel pipe is not stainless steel tube, not the alloy steel pipe, time is long, the fog and rain weather will rust, to teach you about the spiral steel pipe derusting method below:

Spiral steel pipe rust after using a wire brush tool for steel surfaces such as grinding, spiral steel pipe cleaning and preheating can remove loose or cock scale, rust, slag, etc. Hand tools can achieve derusting Sa2 level, power tool cleaning can reach grade Sa3, if solid iron oxide adhered on the surface of the spiral steel pipe, tools, cleaning effect is not ideal, anchor pattern depth of anticorrosion construction requirements.

On the basis of the traditional application and added new applications, this makes the use of spiral steel pipe more fruitful, at the same time reduce the use of spiral steel pipe. Radio frequency sensors to 200 volts, 50 amps of electricity unimpeded fluid spiral steel pipe, through the induction effect of heating experiment samples.

Spiral steel pipe itself is not hot, but a fever in experimental samples significantly. In heating temperature more than arc melting machine, radio frequency sensors will provide more control, the scientists can adjust the alloy composition. Spiral steel pipe pressure ability strong, good plasticity, easy to welding and processing molding; General low-pressure fluid conveying spiral seam submerged arc welding of spiral steel pipe (SY5037-2000), using double, which is used in the automatic submerged arc welding or one side welding into legal system of water, gas, air and steam, etc.
