Problems solved by technology

The basis of trenchless laying technology is to lay the pipeline to the required underground line position by using the trenchless method. The most widely used trenchless technology for laying concrete pipes and steel pipes is the pipe jacking method. In the laying of plastic pipes The most widely used non-excavation technology is the horizontal directional drilling method, because the non-excavation laying needs to pull or push the plastic pipe into the hole drilled at the bottom or into the old pipe to be repaired. During this process, the surface of the pipe will inevitably be damaged. It is very likely that direct contact with sharp stones will form a concentrated load in the pipe wall, thereby damaging the high stress concentration and causing potential use risks. However, the wear resistance of ordinary polyethylene pipe coatings is not high, and the surface is easily worn

Description

technical field [0001] The invention relates to a coating for pipes and a preparation method thereof, in particular to an anti-corrosion and wear-resistant pipe coating and a preparation method thereof. Background technique [0002] The laying link often plays an important role in the cost and energy consumption of plastic pipeline projects. The basis of trenchless laying technology is to lay the pipeline to the required underground line position by using the trenchless method. The most widely used trenchless technology for laying concrete pipes and steel pipes is the pipe jacking method. In the laying of plastic pipes The most widely used non-excavation technology is the horizontal directional drilling method, because the non-excavation laying needs to pull or push the plastic pipe into the hole drilled at the bottom or into the old pipe to be repaired. During this process, the surface of the pipe will inevitably be damaged. It is very likely that direct contact with sharp...
