Experimental Research of Acoustic Emission (AE) Testing of Blowout Preventer in the Process of Pressured

Abstract:

Using acoustic emission (AE) technique, test the blowout preventer (BOP) shell with a crack in the pressing process. Firstly, cut a notch of 100mm long and 5mm wide on a BOP shell and weld partly, then pressurized by pneumatic pumps. Test the BOP shell during the crack propagation by AE. The result showed that the AE technique can reflect the activities of the defects timely and effectively, and the destroy situation of the blowout preventer shell in the process of pressured and the location was accurate.
