Hot Tapping Case Study: Chesterfield Hospital

HOT TAPPING CASE STUDY

Client: Yorkshire Plumbing & Heating Services (YPHS), on behalf of Chesterfield Hospital 

YPHS and Chesterfield Hospital have trusted Ormond Pipework for our services in commercial & industrial gas pipework.   

The problem:

Chesterfield hospital acquired new gas fired boilers to power their heating system.   

To feed the boilers, new branches on their 6” existing underground MDPE gas installation were required. 

The gas supply was constantly in demand, therefore it could not be shut off and the works had to be done live. 

Ormond were brought in to do one 3” hot tapping on to a 6” MDPE gas supply.     

Our solution: 

Ormond attached a hot tapping clamp to the existing gas pipework. 

After a successful pressure test, we began to under pressure drill the new branche. 

Once the live tapping was complete, a safety blank was attached to the valve. 

Hot tapping the connection avoided plant downtime and gas purging, which saved time and expense. 

Tasks involved:

• Hot tapping / under pressure drilling
• Live tapping on MDPE gas installation
• Underground MDPE commercial gas pipework
