Anticorrosion treatment of pneumatic ball valves used in chemical pipelines Pneumatic ball valves are often used in chemical pipelines. Pneumatic ball valves can transmit the pressure and thrust of the connected parts (and compensate for pipeline errors, and cannot absorb axial displacement. So how does the anti-corrosion treatment of the pneumatic ball valve used in the chemical pipeline extend the service life of the pneumatic ball valve, reduce the pipeline maintenance cost, and ensure the safe and effective operation of the pipeline. 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 pneumatic 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 pneumatic ball valve according to the specified requirements using the electrostatic adsorption spraying principle, A fixed coating is formed in high temperature environment to prevent the internal or surface of pneumatic ball valve from being affected by 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 pneumatic ball valve layer and pipe wall shall be used together for the anti-corrosion effect of the whole pipeline, so as to comprehensively guarantee the safe operation of the pipeline system and extend the service life of the pneumatic ball valve used in the chemical pipeline.
