Except the high pressure steel pipe, we also get the abrasion resistant steel pipe which concludes seamless steel pipe for customers. Today, we would like to have an introduction for the usage and maintenance for abrasion resistant steel pipe For the usage, we should know that the current commonly used wear-resistant pipe is to rely on a layer of composite wear-resistant materials to improve the life of the pipeline. And this situation, we will know it would benefits for the protection of goods as well as steel pipes. Secondly, when talked about maintenance, we should know that although the hardness of the composite layer is large, but often very brittle, especially ceramic wear-resistant tube. Thus, we should make protect methods for it. For example, we can make control the factors we can control. During the transportation, maintenance process should be strictly prohibited to fall, knock, hit, to avoid the composite layer and the base of the separation.
