Anticorrosion treatment of electric ball valves used in chemical pipelines Electric ball valves are often used in chemical pipelines. Electric ball valves can transmit the pressure and thrust of the connected parts (and compensate for pipeline errors, and cannot absorb axial displacement. How can the anti-corrosion treatment of electric ball valves used in chemical pipelines extend the service life of electric ball valves, reduce pipeline maintenance costs, and ensure the safe and effective operation of pipelines. The most basic method for pipeline corrosion prevention is to evenly and carefully coat the derusted metal pipeline surface with anti-corrosion paint to isolate it from various corrosive media.
However, the demand for use in chemical anti-corrosion engineering is very high. The produced electric ball valve is made of high-quality carbon steel or stainless steel materials, or according to the user's requirements or drawing requirements, the epoxy resin powder is adsorbed to the inside and surface of the electric ball valve according to the specified requirements by using the electrostatic adsorption spraying principle, A fixed coating is formed in the high-temperature environment to prevent the internal or surface of the electric ball valve from being affected by the medium and environment. The coating thickness is 0.038~0.2mm. In order to ensure that the coating is firmly bonded to the pipe wall, the inner wall of the pipe shall be surface treated. The whole pipeline shall be fixed with pipe clamp support, and the insulation layer shall be added to the electric ball valve layer and the pipe wall to carry out the anti-corrosion effect of the whole pipeline together, so as to comprehensively guarantee the safe operation of the pipeline system and extend the service life of the electric ball valve used in the chemical pipeline.
