FAQ
Q1. What material is the main water pipe made of?
Water mains are usually made of durable materials such as steel, PVC and HDPE. The choice of material depends on the specific application and environmental conditions.
Q2. What are welded pipes and spiral seam pipes?
Welded pipe is formed by joining two edges of the pipe together, which has a strong and leak-proof structure. Spiral seam pipe is formed by rolling a flat metal strip into a tube shape, which has greater flexibility in design and application.
Q3. How do I choose the right pipeline for my project?
Consider factors such as the type of fluid being conveyed, pressure requirements, and environmental conditions. Consulting with a professional can also help ensure you select the best tubing for your needs.
