...Abstract Abstract A 2 ft. diam 20 ft. long cylinder with a wall thickness of 1 in. used for the transportation of a compressed gas failed by cracking. The cylinder was forged in a low ally steel. The working pressure was 3000 psi and it had been in service for about seven years. A longitudinal...

... at the outer part of the teeth. The nitride layer did not stand up to the high and one-sided compressive stress applied in this case and could not prevent pitting. It could even have accelerated the wear by the incipient break down. Gas nitriding at greater depth under application of a suitable special steel...

... and chromium for aesthetic purposes. Applications Brass valves are used extensively in the compressed gas industry. The CDA 377 alloy (60% Cu, 38% Zn, 2% Pb) is used because it is easy to forge into complicated shapes. Second-phase lead particles also allow it to be easily machined. These valves...

Since at least 20% of the tank car (approximately 24.9 m 3 , or 880 ft 3 ) was compressed gas, a considerable amount of energy to drive the fragments would...

In addition, shot peening has been employed to produce a compressive material surface since fatigue usually originates at the surface. Pitting was observed down the throat...
