1 PSK Standards Association PSK 4917 Appendix 14 1 (6) Manufacturer: Yritys Oy RESULTS OF ANALYSIS ACCORDING TO DIRECTIVE 97/23/EY (PED) Address: Purchaser: Tilaaja Oy Document identification: Address: Page: Equipment description Pressure vessel with auxiliaries 1 FLUID P & I diagram Equipment identification Prepared by / Date: Matti Meikäläinen Corrosion - internal - external - condensation Erosion / wear, solid material inside piping Effect of chemical contents Non- stable contents disperses The density or weight of contents in operation or testing Agitation of different chemicals

2 RESULTS OF ANALYSIS ACCORDING TO DIRECTIVE 97/23/EY (PED) 2 (6) 2 INTERNAL PRESSURE Heating Exothermic reaction Endothermic reaction Explosion Fire Drain / vent blocked-up 3 EXTERNAL PRESSURE, VACUUM During normal operation During start-up, shut-down Drain, equipment closed Pressure in double jacket Equipment closed, cooling 3a FATIGUE Pressure fluctuation Temperature changes Vibration (equipment, piping)

3 RESULTS OF ANALYSIS ACCORDING TO DIRECTIVE 97/23/EY (PED) 3 (6) 4 TEMPERATURE Excessive heat income Excessive cooling Insufficient cooling Stop of cooling device Contamination of heating surface Leakage Surface temperature Temperature gradient Remaining temperature during shutdown Risk of creep 5 FLOW Allowed maximum liquid level exceeded Allowed minimum liquid level broken Flow fluctuations, pressure shock, water hammer, turbulence Cavitations Contamination Blockage

4 RESULTS OF ANALYSIS ACCORDING TO DIRECTIVE 97/23/EY (PED) 4 (6) 6 HYDRAULIC PRESSURE TEST Vertical vessel in horizontal position, supporting Weight, base tolerance Vent, drain Effect of fluid to material 7 PNEUMATIC PRESSURE TEST Persons around Soundness of joints Hoses Pressure during test 8 CONNECTED EQUIPMENT Pump, agitator, compressor Soundness of joints Effect of static electricity 9 NON PRESSURE LOADS Piping ces Equipment supports, attachments Lifting equipment Use of hatches

5 RESULTS OF ANALYSIS ACCORDING TO DIRECTIVE 97/23/EY (PED) 5 (6) 10 ENVIRONMENTAL LOADS Wind Earthquake Fire, explosion Snow, ice Rain Flood Landslide, falling snow, rolling stones Lightning Ambient temperature Ground pressure 11 BASE MOVEMENT Offshore construction On board On vehicle 12 PRESSURE DELIMITERS Safety device failure Relief of safety device of rupture disk CSPRS, failure SRMCR, failure

6 RESULTS OF ANALYSIS ACCORDING TO DIRECTIVE 97/23/EY (PED) 6 (6) 13 TEMPERATURE DELIMITERS Length of reaction time Failure 14 HATCHES, BRANCHES Opening as pressurized Opening as filled up Improper torque 15 TRANSPORTATION, USE, MAINTENANCE, INSPECTION Scaffolding Sharp edges Ergonomics Sight glasses Dust explosion or eq. Localization of underground device Balance during transportation, lifting Falling when used This list gives an example of contents. Based on the equipment other risks may occur. The manufacturer shall prepare the and take them into consideration when defining the essential safety requirements the equipment and consider them in the operation.
