Anti-corrosion method of Swagelok needle valve in the United States: First of all, the main materials used for anti-corrosion of the valve body are stainless steel and carbon steel. Although there is a wealth of anti-corrosion information, it is not easy to choose the right one because the corrosion problem is very complex. The difficulty in selecting valve body materials is that you cannot only consider the corrosion problem, but also must consider factors such as pressure and temperature resistance, whether it is economically reasonable, and whether it is easy to purchase.
The second step is to take lining measures, such as lead lining, aluminum lining, engineering plastic lining, natural rubber lining and various synthetic rubbers. If the medium conditions permit, this is a cost-effective method.
Thirdly, when the pressure and temperature are not high, using non-metal as the valve body material can often effectively prevent corrosion.
In addition, the outer surface of the needle valve is also subject to atmospheric corrosion, and generally steel materials are protected by painting.
