I. Product Material
The base material is Q235 carbon steel, formed by straight seam submerged arc welding. The inner and outer walls are coated with blue epoxy powder, using the TPEP anti-corrosion process to isolate the pipe from soil and water corrosion.
II. Product Function
1. Main buried pipelines for municipal drinking water and long-distance urban-rural water transmission;
2. Conveying pipeline networks for sewage treatment and reclaimed water reuse;
3. Underground water supply and drainage pipelines for factories and industrial parks;
4. Pipelines for agricultural irrigation and river water diversion projects.

IV. Product Advantages
The straight seam pipe features standard pipe diameters and reliable weld sealing performance verified by flaw detection. The blue anti-corrosion layer has strong adhesion, while the smooth inner wall resists scaling and meets hygienic requirements for drinking water transportation. It resists acid and alkali corrosion in buried soil environments, significantly extending service life.
