The basic coated steel pipes including spiral, straight seam pipe, seamless steel pipe, etc. They are widely used in pipeline projects in the field of petroleum, chemical, natural gas, heating, sewage treatment, water, bridges, steel structure, pilling and marine construction.
Energy-saving and cost-
The service cycle is as long as 30-50 years, and the cost advantage of the whole life cycle is significantly better than other pipelines. And high transmission efficiency, significantly improve operating efficiency, reduce operating costs.
Pipeline bearing capacity is strong, anti-seismic, anti-subsidence, anti-collapse, suitable for different hydrological and geological conditions
The inner wall anticorrosion is food grade coating, good health performance, acid, alkali, salt, bacteria resistance; Laboratory accelerated aging test, boiling test, seawater immersion test, service life of 30-50 years
