In a past life I spent 4 years in a manufacturing facility that made high pressure equipment. Compressors up to 30,000 psi, valves up to 200,000 psi, pumps up to 150,000 psi and the like.
We were commissioned to build several sets of compressors for the U.S. Navy for a diving mission. The compressors were for refilling diving tanks. One for oxygen, the other for helium. Since there was the possibility of error, both compressors had to be built to standards for oxygen service.
I was instructed in the properties of oxygen under pressure, and was required to perform oxygen cleaning in a clean room environment. The compressors were of the diaphragm type to isolate oils from the process being pumped.
What I learned was that oxygen under pressure accelerates combustion. Oxygen under pressure can initiate combustion with some materials. Steel will burn with an open flame in the presence of pure oxygen. However, the explosion bit is mostly not true. Petroleum products will spontaneously ignite in the presence of pure oxygen. They will not explode unless confined. Petroleum residue in a gauge for example will burn through the metal (usually brass) but will only explode if confined.
Special materials are used for oxygen service. Compressor parts that come in contact with oxygen under pressure are usually made of a material known as Monel metal. This is an alloy somewhat similar to stainless steel, but it is more of a nickel and copper alloy. Oils used in oxygen service are halogen based oils.
Contrary to commonly held beliefs, oxygen does not burn nor is it explosive. Oxygen supports combustion. Explosions only occur when fuel and oxygen are confined.

Today's Featured Article - Restoration Story: Fordson Major - by Anthony West. George bought his Fordson Major from a an implement sale about 18 years ago for £200.00 (UK). There is no known history regarding its origins or what service it had done, but the following work was undertaken alone to bring it up to show standard. From the engine number, it was found that this Major was produced late 1946. It was almost complete but had various parts that would definitely need replacing.
