Spiral welded steel pipe is used for non-toxic 8710 anti-corrosion spiral steel pipe for drinking water , and is widely used in water quality pipeline. We use this kind of pipe, IPN8710 drinking water pipeline anti-corrosion, IPN8710 pipe fittings inner wall (drinking water) anti-corrosion, steel pipe inner wall non-toxic paint anti-corrosion, three-layer poly 3PP anti-corrosion. It not only guarantees the quality of water quality, but also guarantees the water content. In addition, our spiral welded steel pipe are widely used in anti-corrosion engineering such as sewage treatment, oil pipelines, natural gas pipelines, urban heating pipelines, water supply pipelines and electric power. Sewage treatment: sewage treatment discharge pipe, sewage pipe and biological pool anti-corrosion engineering Agriculture: agricultural irrigation pipe, deep well pipe, drainage pipe and other networks, corrosion resistance is better than steel structure is conducive to steel pipe fire and fire.
