Are there any specific anti-corrosion and rust prevention measures to stop control valves from rusting?
Thread Content
There are quite a lot of corrosive gases in the factory’s workshops; even the newly installed control valves have started to rust. Is there any special anti-rust or anti-corrosion oil or something similar that can be used to prevent this? The big names? Help! ! Urgent! Urgent! Urgent! ! ! !
The material of the valve is one aspect, and its surface treatment is another; in particularly harsh environments, more solutions need to be found.
Requirements are placed on valve manufacturers to apply the primer and topcoat several times; generally, valve manufacturers complete the process in just one application. What corrosive gas? Does the paint corrode as soon as it’s installed? Was the surface paint damaged during installation?
Some acids are causing corrosion not at the areas where paint is applied, but rather on the connection bolts, set screws, and similar components that have rusted
It would be better to use a chrome-plated hex key or stainless steel
You can apply some lubricant, butter
When placing your order, you can request this from the valve manufacturer – just choose stainless steel for all the bolt connections on the valves. The bolts on our cast steel valve bodies are made of stainless steel as well; it doesn’t increase the cost much, but after some time, the difference will be evident when using the valves in practice.
