1. During transportation, loading and unloading, and construction site construction, coated steel pipes are strictly prohibited from being thrown or violently impacted;
2. coated steel pipes should not be buried in reinforced concrete structural layers;
3. The installation of coated steel pipes should be gradually connected from large diameter to small diameter, and the pipe openings should be blocked in time;
4. Welding is prohibited during the installation of coated steel pipes;
5. When installing coated steel pipes, if the pipe diameter is not larger than DN50, a pipe bending machine can be used for cold bending, but the bending radius of curvature shall not be less than 8 times the pipe diameter, and the bending angle shall not be greater than 10°.
In addition, coated steel pipes are not thermally insulated pipes. Many people may see that coated steel pipes are steel pipes coated with a layer of plastic, which is thicker than the original steel pipes. They subconsciously think that coated steel pipes have the effect of thermal insulation. This kind of Familiarity is wrong. Although coated steel pipes are thicker than ordinary pipes, their function does not have the effect of thermal insulation. The main features of coated steel pipes are their anti-corrosion and environmental protection effects, which make the pipes have a longer service life and ensure the constant flow of the medium transported in the pipes. Chaos and other characteristics.
