Stainless steel pipes in which water flows

Why?

The best way to eliminate water flow in stainless steel pipes is to use a water filter to remove any debris or contaminants from the water before it enters the pipe.

Corrosion occurs in the pipes

Why?

1. Use corrosion-resistant materials such as stainless steel, copper, or brass for pipes. 2. Use a protective coating such as epoxy, zinc, or galvanized steel on the pipes. 3. Install an anode rod in the pipes to attract corrosion away from the pipes.

The pipes are made of a material that is prone to corrosion.

Why?

The best way to eliminate corrosion is to use a corrosion-resistant material such as stainless steel, aluminum, or plastic. Additionally, you can coat the pipes with a protective coating such as a zinc-based paint or a specialized corrosion-resistant coating. Finally, you can also use corrosion inhibitors to help reduce the rate of corrosion.

The pipes were not properly coated with a protective layer to prevent corrosion.

Why?

Apply a protective coating such as epoxy, polyurethane, or other suitable material.

The coating materials were of poor quality.

This is the fundamental reason for the problem (FRP).

Invest in higher quality coating materials that are designed to last longer and provide better protection

    You did a great job. I like your Root Cause Analysis you completed with Cause and Effect Chain and with 5+Whys. Thank you.

    The vacuum furnace is used for sintering parts made of metal powder. To keep the shape of the parts, a binder is used. The main problem is that the vacuum furnace becomes dirty and needs a very long cleaning. Regular washing was not successful. We investigated the process and found that washing should be dedicated to the conversion of the material into a form that results in the formation of gases having low temperature of the condensation
