Product Features

Spiral Welded Steel Pipe with High Cathodic Stripping Resistance and Bending Strength
1. Corrosion Resistance
Our Spiral Welded Steel Pipe boasts the superior corrosion resistance of advanced polymer materials like polyethylene and epoxy resin, which are renowned for their exceptional ability to shield against corrosive elements. This impressive feature effectively safeguards the pipeline from the detrimental effects of soil and fluid, significantly extending its operational lifespan.
2. Excellent Hydraulic Properties
Designed with a smooth inner wall, our pipe minimizes scaling and sports a low friction coefficient. Coupled with its non-adhesive properties, this ensures optimal conveyance capacity, while simultaneously reducing both pressure loss and energy consumption during water transmission.
