Process Engineering Division – Instrumentation and Automation Section – Daily Question – Question from 2020-10-23: Discussion question: 274. Briefly describe the main aspects of visual inspection for orifice plates
The right-angled inlet edge on the upstream side of the orifice plate opening, the outlet edge on the downstream side of the orifice plate, and the circular downstream outlet edge of the orifice plate opening should be free of burrs, scratches, and visible damage.
The edge of the right-angled inlet on the upstream side of the orifice, the edge of the outlet on the downstream side of the orifice, and the circular outlet edge on the downstream side of the orifice opening should be free of burrs, scratches, and visible damage.
Are there burrs and scratches on the edges where the fluid comes into contact with the orifice plate upstream and downstream?
Are there burrs and scratches on the edges where the fluid comes into contact with the orifice plate upstream and downstream?
1. The openings in the orifice plate should be round; there should be no defects such as gaps. 2. Confirm the front and back orientation of the orifice plate to avoid incorrect installation. 3. Verify that the orifice plate is manufactured in accordance with the requirements specified in the calculations (material, pore size, etc.)
