18" PeteStop® Blocks Caustic Pipeline Product on Mountainside

Turkey

INTRODUCTION

Mining company needed to install valves on a mountainside pipeline that contained toxic materials.

PROBLEM

Here are some of the requirements of the job:

• Pressure was unknown but max could peak at 2 Bar (29 PSI)
• Toxic Material could not be exposed to air
• 6 hours max the pipeline could be shut down
• Millions per day in revenue lost if system entirely shut down
• Pipeline material HDPE

SOLUTION

Working with the mining company, Petersen engineers proposed using 18" PeteStop® Inflatable Line Stops. The lighter weight equipment, smaller tap hole and larger pipe surface contact of an inflatable plug ensured a positive seal while saving time and money.

RESULT

Contractors were able to have a positive isolation of the pipeline to install the valve with plenty of time to spare. Everyone was pleased with the result.
