What are the anticorrosion methods of welding flange

Many, but in flange, flange every welding process to consider anti-corrosion method, because this directly affects the sealing performance of the pipeline connection. What is the anticorrosion method of welding flange joint with you.

There are usually two methods, spraying antirust paint and painting. However, both sides of France need to have certain costs, so how to reduce costs is something we need to consider. There are two ways to do this:

What are the anticorrosion methods of welding flange

After calculating the square meter of stainless steel, the square meter of flange is multiplied by the unit price to calculate the anti-corrosion cost of each elbow joint.

Secondly, the square area of elbow, flange, tee and other products is generally calculated by theory. In other words, only the length and width of the fitting are measured, not the thickness of the fitting.

In this way, the two flanges can have good contact, and the sealing performance of the flange will not be affected by the surface roughness and surface pretreatment. In addition, when we use flange connection, we can ensure that the flange surface is free of cracks, corrosion and deformation. At the same time, the thickness of the flange should be increased.
