How about the wear and impact resistance of epoxy resin anti-corrosion steel pipes
The paint film of epoxy resin anti-corrosion steel pipes after curing is tough, water resistant, non-toxic, and non polluting to water. Strong adhesion, with good adhesion between paint films. Excellent rust and water resistance, using excellent rust resistant raw materials to ensure its rust resistance. It has excellent mechanical strength, tough paint film, and wear and impact resistance. High solid content and thick coating. Cure at room temperature to form a film. No need for large-scale baking equipment.

How to design and construct the trajectory of overhead insulated steel pipes
The causes of accidents in horizontal directional drilling of overhead insulated steel pipes can be roughly divided into broken drilling tools, drill pipe burying and sticking, flat and immovable pipes when the pipes are pulled back, and damage to the original underground buildings. The reasons for the breakage of drilling tools: ① The drilling tool has excessive wear after long-term use; ② The drill pipe is thin and worn, and when drilling guide holes, the curvature radius is too small. The drill pipe breaks under repeated shear forces. Preventive measures: Regularly inspect drilling tools. No need to wear and exceed the limit of drilling tools.
How to repair the anti-corrosion coating on the port after the spiral anti-corrosion steel pipe is boxed
When exporting spiral anti-corrosion steel pipes, in order to effectively protect the anti-corrosion layer, the outer layer of the spiral steel pipe needs to be packaged. However, during the container loading process, it is inevitable that the port of the anti-corrosion spiral steel pipe will be damaged. When packing, a forklift is usually used to lift one end of the anti-corrosion spiral steel pipe. Friction between the forklift and the inner wall of the anti-corrosion spiral steel pipe will wear off a part of the anti-corrosion layer, which requires timely repair of the anti-corrosion spiral steel pipe after loading. Below are the specific steps for repairing:
