Description

Technical Field

[0001] This utility model relates to the field of PVC pipes, and in particular to a wear-resistant PVC pipe. Background Technology

[0002] PVC pipes are widely used in industrial, construction, and agricultural fields due to their advantages such as low cost, corrosion resistance, and ease of processing. However, traditional PVC pipes have the following problems when transporting highly abrasive media: poor wear resistance: ordinary PVC pipes have low surface hardness and are easily worn by particulate materials, leading to thinning of the pipe wall or even cracking, resulting in a short service life. In high-wear environments, the service life of traditional PVC pipes is usually short and requires frequent replacement. Insufficient impact resistance: ordinary PVC pipes are prone to cracking when subjected to impact, affecting the safety and reliability of the pipeline. Therefore, a wear-resistant PVC pipe is proposed. Utility Model Content
