Gas Purging Case Study: Cargill

GAS TESTING CASE STUDY

About: Cargill provides food, agriculture, financial and industrial products and services to the world. 

The problem:

Cargill required industrial gas pipework to be decommissioned at one of their chemical plants.

This was so the pipework could be disconnected and two condemned steam boilers could be removed. 

Our solution: 

As specialist industrial Gas Safe engineers, Ormond Pipework Services Ltd, used nitrogen to purge the gas inside the existing pipework. 

We purged out 4 cubic meters of natural gas and monitored the air to gas ratio. 

We then issued a commercial Gas Safe certificate to ensure the pipework was clear of gas and was safe to work on. 

Once the disconnections were complete, our engineers returned to perform a gas tightness test and direct purge. 

Finally, another Gas Safe certificate was issued to ensure the commercial gas installation was safe to use.   

Tasks involved:

• Indirect gas purge 
• Gas tightness test
• Direct gas purge 
• Industrial Gas Safe certificate
