In order to protect electric power and communication cables laid in railway, highway, subway, municipal construction and other system fields, cable protection tubes are generally installed on pipelines when cables cross obstacles such as railways, highways and rivers. At present, N-HAP hot-dip plastic steel pipes are generally used for cable protection in the market. Because it is often used for road cable protection, it is also called hot-dip plastic steel cable protection tube. N-HAP hot-dip plastic steel pipe has good insulation performance, chemical stability, no rust, no aging, wide temperature range (-40℃-80℃), and can adapt to various harsh geographical environments. Hot-dipped plastic steel pipes and other products can be used for plastic-coated steel pipe protection pipes such as submarine tunnels and cross-sea bridges. Of course, the most important thing when purchasing is to pay attention to the quality of products, which can be identified from the following aspects:

You can look at the surface first. Generally, the surface finish is good, and the quality is qualified without cracks. You can also scrape the surface of hot-dipped plastic steel pipe by hand or other objects to see if the coating falls off too easily. If it doesn't fall off, the quality is ok. If it falls off with a slight scratch, it means that the product quality is not good.
