Key Aspects of Success of a City Gas Distribution Project-The UK Experience

1. Key Aspects of Success of a City Gas Distribution Project-The UK Experience

2. Polyethylene (PE)The Material of choicefor medium & low pressure mains WHY???

3. PE-The Material of choicefor medium & low pressure mains • Homogenous fully fused system • The joints are stronger than the pipe • Lack of corrosion • Maintenance free • Fully end loaded-No thrust blocks • Flexible • Lightweight and easy to use • Use of ‘no dig’ technology

4. In the UK • Other material alternatives do not share PE’s advantages. • For instance, there are about 23,000 fractures and corrosion failures of iron mains across the United Kingdom each year. • Of these events, the majority are located and dealt with in a safe manner. However, on average, about 600 of these result in the leakage of gas into buildings and annually this results in 3 to 4 major incidents involving fire or explosions.

5. What does this tell us? • PE pipe is very flexible and durable, it also has the potential to last over 100 years • A well made joint is equally durable BUT…. it must be made correctly!

6. 1995 Kobe Earthquake • Magnitude 7.2 • Largest earthquake in Japan since 1923 • Over 5,000 deaths • 300 fires started within minutes • Mainly caused by ruptured gas pipe lines

7. Post Kobe Earthquake • No reported gas leaks from PE • Resulted in both Gas and Water sectors switching to PE • Over 500 EF and ABF machines purchased by Toho and Osaka gas for PE installation after the disaster

8. PE– Potted History • Really took off in 1950’s & 60’s • Used to carry gas in late 60’s • Late 1970’s Transco starts to use Aldyl PE (Dupont) for gas distribution (Class B), MDPE (PE80) introduced • 1979 First electrofusion used for pipeline repairs in gas industry • 1981 Electrofusion adopted for main method of jointing in gas industry • 1984/5 MDPE introduced to UK water industry • Early 1990’s introduction of Fully Automatic Butt Fusion Machines and data download • Late 1990’s-present day Electronic downloads/analysis

16. Data Transfer Benefits 1) Allows the utility & contractor to quickly and easily assess the performance of both operator and equipment saving you both time and money. In other words ‘direct supervision without being there.’2) It will highlight any potential problems as they occur rather than after the pipeline has been tested and buried – with all the additional costs that would inevitably be incurred. 3) Provides paperless electronic reports that can be both emailed and stored on disk, hard-drive etc demonstrating the quality of work undertaken to ISO standards – at minimal cost! 4) The ability to produce statistical data for management use on such things as pipe usage by size and location, number of joints per man per hour by pipe size and overall quality improvements, to name but a few. 5) The ability to store easily accessible, encrypted data that will tell the truth about each joint, until the data file is deleted. 6) Increasingly utilities are requesting that the contractor provides this information for quality assurance purposes as well as providing a cost effective way of remotely managing work carried out. 7) Even where the utility does not insist on such information the system provides a traceable quality record should disputes occur in the future and also helps contractors ensure that they are on a ‘level playing field’ by offering proof of work quality.
