Report of Analysis
SAMPLE ID: #7-24” Permalok Connector Joining System
SUBJECT: Hydrostatic Pressure Testing
TESTING SITE: B & D Metals Products, 5980 St. Louis Avenue
PROCEDURE:  

Testing blinds were attached to a shortened length of the connector assembly and placed into the test fixture. Prior to assembly and installation both male and female couplings were visually examined for proper tolerances, joint type and fit up. The coupling halves were then pressed together using the necessary jacks, shims and clamping fixtures. Figure 2 illustrates the typical set up and configuration of the fitted 24” Permalok Connector

The sealed unit was then hydrostatic pressure tested with potable water to a pressure of 150 psi and held for 30 minutes. The pressure was then increased to 300 psi and held for an additional 15 minutes.

RESULTS:

No deformation or drop in pressure was noted during the testing of the above identified connector assembly.
