Corrosion-resistant carat pipes, chemical wastewater pipelines

In the chemical production process, the wastewater medium is complex, often containing acids, alkalis, salts and various organic solvents, which poses extremely high corrosion resistance requirements for transportation pipelines. Traditional metal pipes are highly susceptible to electrochemical corrosion, and carat pipes, with their unique material and structural design, provide a long-term and stable solution for chemical wastewater transportation.

Carat tube is a high-density polyethylene winding reinforced tube, and its core advantage lies in the chemical inertness of the material itself. The molecular chain of high-density polyethylene is symmetrical and stable, which can effectively resist the erosion of most acids, alkalis and organic solvents, and will not rust or pitting and perforation like metal pipes. For the initialized wear often accompanied by chemical wastewater, the inner wall of the pipe is smooth and wear-resistant, the roughness coefficient is extremely low, and it is not easy to scale under long-term operation. It can maintain a stable overcurrent section and reduce maintenance frequency.

In terms of structural technology, the carat pipe is formed by hot winding, and the pipe wall is closely combined with the pressure-bearing layer by the structural wall to form a reinforced profile similar to "T" type or "ripple". This structure not only realizes lightweight, but also gives the pipe excellent ring stiffness and external pressure resistance, even if it is buried in complex foundation conditions, it can withstand static soil load and ground dynamic load. The pipe interface is mostly connected by socket electrofusion, and an integrated closed system is formed after welding, which eliminates the potential pollution risk of sewage leakage to soil and groundwater.

In practical applications, the drainage pipe network of chemical parks, acid and alkali waste liquid collection systems, and industrial circulating water sideline treatment pipelines are all suitable for the selection of carat pipes with matching specifications. When selecting the type, it is necessary to refer to the concentration, temperature and design pressure of the conveying medium, and refer to the relevant hydraulic calculation and chemical resistance data table to ensure the long-term safe operation of the pipe under specific working conditions. Through reasonable pipeline foundation treatment and backfill compactness, carat pipes show excellent engineering adaptability and life-long economy in the field of chemical wastewater transportation.
