Description :
This product is a large-diameter spiral seam submerged arc welded steel pipe specially designed for municipal and industrial fields. The inner wall is treated with professional cement mortar for anti-corrosion lining. This structure combines the high-strength mechanical properties of spiral steel pipes with the excellent corrosion and wear resistance of cement mortar, making it an ideal choice for long-distance fluid transportation pipelines.
The main selling point lies in its excellent inner wall anti-corrosion ability. The cement mortar lining forms a dense and smooth protective layer inside the steel pipe, effectively isolating the erosion of water, sewage or chemical media on the steel substrate, significantly extending the service life of the pipeline, and reducing maintenance costs in the later stage. At the same time, the smooth inner wall significantly reduces fluid transport resistance, improves transport efficiency, and reduces the risk of scaling and blockage, making it particularly suitable for drinking water transport systems with high requirements for water quality and hygiene.
Typical usage scenarios include: laying of main roads in urban water supply networks, large-scale drainage and sewage pipelines in sewage treatment plants, irrigation and water diversion projects for farmland, and circulating water systems in power plants. For pipeline projects that require underground laying or crossing complex geological conditions, this product can provide long-term stable operation guarantee with its sturdy steel shell and reliable internal protection.
The target audience mainly includes municipal engineering contractors, procurement departments of water companies, large construction and installation enterprises, petrochemical construction units, and material procurement managers of various infrastructure projects. The product supports customizing different diameter and wall thickness specifications based on engineering drawings to meet diverse construction needs and ensure project quality and safety.
