Bryan Hauger Consulting, Inc. – April 2019

Overview Objectives Recent Developments Process for Qualification Heat Fusion Joining Types Discussed

• Butt Fusion• Socket Fusion• Electrofusion Coupler• Conventional Saddle• Electrofusion Saddle

Conclusions


Objectives Share Best Practices for Procedure Qualification Improve understanding of testing procedures

used to qualify plastic pipe joints in compliancewith 49 CFR 192• Only Heat Fusion Joints will be discussed• Lots of Photographs to Assist Visual Learners


Recent Developments Revisions to 49 CFR 192 were published by

PHMSA in November of 2018• Increasing the design factor of polyethylene pipe• Adding PA12 and modifying PA11 rules• Incorporation by reference of ASTM F2620 into the

qualification of procedures and personnel for joiningplastic pipe

• Effective Date Originally January 22, 2019


Best Practices Natural Gas Operator provides written procedures

for joining operations Independent Professional verifies conformity to

the written procedure by observation of all jointsfor testing

Joints tested by an independent laboratory Document created including;

• Written Procedures for Joining• Confirmation of Conformity to the Written Procedure• Results of Testing

Conclusions Best Practices for Procedure Qualification

eliminate potential for conflicts of interest Third Party Testing is available to assist Natural

Gas Operators to Qualify their written joiningprocedures

Natural Gas Operators have the responsibility todetermine that a joining procedure is qualifiedand complies with 49 CFR 192.283
