Pipeline Defect Repair Workshop

Presented by Blade Energy Partners and RSI Pipeline Solutions

We will discuss the evaluation of most common pipeline defects and damage, and their appropriate repair options. The workshop will include hands-on demonstration on pipe surface preparation, defect examination, and repair installation. Applicable ASME B31.8 and B31.4 repair requirements and PHMSA regulations will also be discussed.

Day 1:

8:00 AM
