Failure Mode and Effect Analysis (FMEA) of Pipeline

2020-7-25 · This article provides a practical method for applying failure mode and effect analysis (FMEA) on oil export pipeline ball valves. These valves have been selected for analysis because they are the largest, heaviest, and most important valves on topside platforms in the offshore sector of the oil and gas industry. FMEA is a systematic approach for evaluation and identification of potential ...

Failure Analysis of Ball Mill Liner_Goldpro

Failure Analysis of Ball Mill Liner-Goldpro-First, the main function of the ball mill liner is to protect the mill barrel and drive the grinding ball inside the grinding to do the sloping movement to smash the material in the crushing mill. To this end, the mill liner is required to have sufficient lifting and disturbing ability for the grinding ball.
