Spiral steel pipe is made of hot-rolled steel strip as raw material, coiled into pipe, double-sided submerged arc welded, and the weld is spiral-shaped; According to the material, it can be divided into three categories: carbon steel, stainless steel, alloy steel, according to the pressure level, ordinary conveying and high-pressure special models, which have the advantages of high cost performance, strong pressure bearing capacity, and wide specification adaptation, and can be customized on demand for large-diameter and thick-walled models to meet the needs of multi-scenario industries.

Core use

1. Municipal infrastructure: The main pipe network of urban water supply/drainage, sewage treatment, and gas transmission is the core pipe of urban pipe network construction.

2. Energy transmission: long-distance oil and natural gas transmission pipelines, including land pipelines and some shallow sea oil pipelines.

3. Engineering construction: bridges, wharves, steel structure supports, steel pipe piles for piling, as well as power plant circulating water pipelines and chemical fluid conveying pipes.

4. Mining industry: the transportation pipeline of mine tailings, slurry, and underground drainage, which is resistant to wear and corrosion and adapts to the harsh working conditions of the mine.

5. Agricultural water conservancy: farmland irrigation main pipelines, water conservancy hub water transmission projects, and flood control pipelines are suitable for complex outdoor environments.

6. Steel structure application: Load-bearing components of columns and beams in large factories and steel structure buildings to replace some profiles and reduce costs.

Core advantages are supplemented

It has the characteristics of high production efficiency, long length of a single pipe (reducing interface), and good resistance to external pressure, and can greatly improve the service life of outdoor and buried use after anti-corrosion treatment (epoxy coal asphalt, 3PE anti-corrosion, etc.), and is a cost-effective rigid pipe in industrial transportation and engineering construction.
