Storage Tank Inspection and Failure Analysis

Piping Failure Analysis
ASME Code for Pressure Piping B31.3 is an American National Standard for Process Piping and contains fiberglass installation and inspection criteria.

The subject photographs were taken during an inspection of failed piping and fittings in a chlor-alkali production facility located in Washington state. The first photograph shows a saddle on a 6 inch pipe in brine service that has been repaired and continues to leak. The second photograph shows 2 inch piping and elbows where excessive adhesive was applied, the fitting “backed out” and leaked. These observed failures were the result of faulty fitting workmanship training, not adhering to practices specified by the pipe manufacturer and ASME B31.3.
