Static electricity bonding of oxygen pipelines
Thread Content
For static bonding of oxygen pipeline flanges, the wires use solder paste and an oily substance; the bonding is achieved by welding screws to the pipes in order to connect the static bonding wires – is degreasing necessary? Urgently needed
The wires for static bonding don’t need to be degreased, right?
There is no need for that. Degreasing refers to fittings that are in contact with oxygen.

Electrostatic bonding is not necessary; this device comes into contact with oxygen in the air, and there’s no problem with that. Even if there is a small amount of grease, prolonged contact only leads to a slow oxidation process – there’s no risk of volume expansion or combustion. However, it’s essential to thoroughly degrease oxygen pipelines. I’ve heard that alkaline solutions and steam are used for cleaning or purging these pipelines. The reason for degreasing oxygen pipelines, in my opinion, is that fats can easily react with flowing oxygen, leading to combustion and explosion accidents. It’s worth noting that I saw a case on a forum recently: it was said that the floor where oxygen equipment and oxygen generation devices are located should not be made of asphalt, as the volatile substances in asphalt could combine with oxygen (rich in oxygen) to form explosive mixtures.
