The grayish-white \"frost\"-like substance on the wall of the steel-lined F4 pipe

Thread Content

The steel-lined F4 pipes at the installation site have been there for over a month, but installation has not yet been completed due to a lack of some materials. It has now been found that there is a layer of gray \"frost\" on the inner wall of the tube; after wiping it away with your hand, the wall becomes smooth again as before. I don’t know what it is? What are the harms?

Someone pointed out that there is a problem with the material; that’s dangerous.
