I have noticed that in my company, due to the use of a centralized lubrication system with 0# lithium-based grease, a large amount of black, viscous liquid is coming out from the edges of the nozzles. Although measures have been taken, some of this liquid still seeps out. I believe this liquid is a mixture of tar, naphthalene, water, acidic substances such as H2S, along with 0# lithium-based grease. This mixture first dissolves the anti-rust paint on the surface of the pipes, and then gradually corrodes the pipes made of Q235-B material. I’m not sure if it’s possible to solve this problem at its source Please discuss
