The main issue is corrosion of production equipment. Especially in the urea production process, equipment needs to operate in high temperature, high pressure, and highly corrosive environments, which can lead to gradual corrosion of equipment materials. Urea ammonium solution has strong intergranular corrosion ability on stainless steel, and an increase in sulfide and water content in the solution will exacerbate the degree of corrosion.

The reducing substances generated during the production process, damage the surface oxide film of stainless steel materials, so that the material loses its anti-corrosion properties. The plant needs to take anti-corrosion measures to reduce steel corrosion and improve the safety of equipment operation.

Anti-corrosion treatment of concrete surfaces using heavy duty anti-corrosion materials to prevent corrosion from chemical seepage.

There are systematic and professional coating integration, for different structural corrosion characteristics and requirements, diversified customized solutions.

Based on industry standards, we pay attention to coating and material matching, and adopt new functional materials such as

acid penetration resistance, alkaline friction resistance and high temperature acid resistance.

Professional tooling and process, accumulate experience and pay attention to details, professional testing means and equipment, professional evaluation system.
