Shandong Songshang Composite Materials Co., Ltd. offers steel-lined plastic pipes that are formed from carbon steel tanks as the base and polyethylene as the raw material, using rotational molding technology to create a one-time, whole-formed anticorrosive storage and transportation device. First, a tortoise shell-like steel mesh is welded onto the inner surface of the steel body, followed by the rotational molding process that fuses the steel body surface, steel mesh, and polyethylene plastic into a single unit. These steel-lined plastic pipes possess both high physical and mechanical properties and high chemical corrosion resistance.

Steel-lined plastic pipes feature a smooth, even, and robust inner surface, offering superior corrosion resistance, non-leakage, non-flaking, wear resistance, ability to withstand certain pressure, high-temperature tolerance, and longer lifespan. These pipes are suitable for storage and transportation equipment for various chemical solutions.
