Industrial Refrigeration Service Welding

Industrial Refrigeration Service Welding of the Pipework

The ammonia had been removed to perform industrial refrigeration service welding. This was carried out using the zero-zero breaking in procedure. This visit was to replace rusted pipework. The welder got strait to it: grinding out the components ready for the welding. After the welding was completed, the vessel was leak tested and pressure tested. Another part of the system which contained liquid required works so:

Ammonia Refrigerant Transfer Pump

The ammonia refrigerant transfer pump failed during the recovery of 6 tonnes of anhydrous ammonia. There was a tight schedule as delays would mean less time for the upgrade during factory shutdown. Our engineer quickly took the side covers off the ammonia refrigerant transfer pump. He found that the coupling had come loose. Luckily, he found it to be not damaged more than scratches. Therefore, he bolted it together again and tested it: back in production

Shell and Tube Service

After the above was carried out- the plant was inspected. The condenser had failed on the industrial refrigeration plant. Ammonia had been leaking into the water system causing the ammonia warning alarm being triggered with plant shut down

Burst Tubes

Our shell and tube technician identified the tubes. Then, industrial refrigeration service welding was carried out on the burst ones. Dehydration was easy as the ammonia refrigerant had been leaking out with not much water getting in. Also, the water system was drained prior to removing the refrigerant

Run Testing

The customer signed off the paperwork for the job. The readings were monitored for some time to look for any abnormalities. All readings were okay- another happy customer!
