Can acetylene not come into contact with copper, mercury, or silver?
Thread Content
For devices used in the production of acetylene, we were told that tools and equipment made of copper cannot be used; it is said that acetylene reacts easily with metals such as copper, mercury, and silver to form unstable substances that can cause explosions. Article 7.2 of GB10665-2004 on calcium carbide (acetylene) states: \"Acetylene readily reacts with silver salts, copper salts, and mercury salts to form unstable and explosive acetylene compounds.\" ”These are the specific standard regulations that can be seen. So, the question arises: why don’t the standards include \"silver, copper, and mercury metals\"? Rather, what about these metal salts that are written about?
Aren’t the pressure regulators for acetylene cylinders all made of copper?
It is explained that the valve of acetylene cylinders is made of a copper alloy with a copper content of less than 70%, making it safe. But there is no further technical explanation: lol
