Sample of Risk Assessment for Pressure Testing. In this short article, We will provide examples of five such incidents that can be used as a help to understand the hazards and dangers involved during pressure testing. Good preparation is always essential to avoid incidents.

Root cause analysis shows that a plastic sheet that was protecting the roof was trapped in the vent which created a vacuum. This incident happened while filling the tank (Refer to Fig. 3.2.4 Immediately stop and correct any safety related non-compliant activities. 1. A pressure vessel nozzle is an opening in the pressure vessel through which fluid enters or exits the pressure vessel. ARV ensures that a pre-determined minimum flow is transferred through a centrifugal pump at all times. Wearing of safety glasses for operator and those in the working environment mandatory. Pressure testing is a very small part of each of these standards. It was verified later that the steel legs had its thickness reduced by up to 8 mm, with pitting holes of up to 10cm2. Good coordination is of utmost importance to avoid performing the hydro-test at the same time as other operations. endobj The emphasis is on the The main cause was the Severe corrosion of the legs under the concrete fire protection. #Robotics #ArtificialIntelligence #IoT #AI #MachineLearning……, Sarum Hydraulics Ltd Unit 1 Danebury Court Old Sarum Park, Old Sarum Salisbury, Wiltshire SP4 6EB, T: +44(0)1722 328 388 E: Company Registered Number 3037960 in England CODE U5148 DUNS 778875971  ISO9001:2015 Quality Certificate Code of Conduct Environmental Policy Anti Slavery Policy.

Even though a gear-box is not a pressure vessel, but its productivity may lead to a risky attitude. This website uses cookies to improve your experience while you navigate through the website. Thorough investigation and tests confirmed that the following factors contributed to the sphere collapse: A complete inspection must be performed visually and if required with NDT before pressure testing of an old vessel. 14. Great list – one I will be sharing for sure! Its instantaneous release works like a bomb and may cause severe damage to persons and equipment. The image shows an exploded vessel that happened during hydro testing of a new vessel. Our You Tube video “how to burst test” shows a Micropac pump used for a simple but safe burst test.

Position unit under test such that projectiles cannot cause injury to operator or bystanders, or damage to the surroundings. For example, ASME B31.1 – 2012 Power Piping covers the testing procedures for hydrostatic and pneumatic tests in only two pages. The root cause of the incident is not known fully.

Ensure that operators are trained in using the equipment and made aware of all risks pertaining to safe use as identified in this risk assessment. The new concrete had not adhered to the old concrete, again letting water in. Welcome to my space, I am Anup Kumar Dey, an experienced piping engineer from the last 15 years. 2) with water from a fire hydrant. Ensure all other equipment external to SHL unit is regularly maintained, inspected, tested and calibrated in accordance with manufacturer’s procedures or as defined otherwise. 4), Its legs suddenly collapsed. Just like every other activity in the workplace, you must assess risk. Ensure all persons in the working environment are suitably protected from flying debris and hydraulic media in the event of rupture. The deluge system had been tested with saltwater, increasing the possibility of corrosion. Poor workmanship during Repairs had been done to the concrete. Just like every other activity in the workplace, you must assess risk when pressure testing hydraulic items.
