Introduction: Industry Need

1. Unknown Performance of Connections• Pipe Performance exceeding connection ratings

2. Supply Requirements: Competition • Multi-source for meeting schedule requirements

3. Cost: Competition As important as the tubular Failure- Financial Loss Liability- life and property

DEA 151 4

Introduction: Operator Experience

1. Failures are found two ways:• Laboratory- Rare for a test to go without performance issue• Field -Most costly / HSE implications

2. Operators have: Totally Eliminated Field Failures through an integrated

Qualification Program Program involves applying what was tested, running per test,

and applying within the limits of qualification Independent verification of test results

Connection Reliability

Foundation: Design Related (FEA, ISO 13679, Design Calcs)

Manufacturing (Complete Specifications)

Installation: Torque, RPM, Thread Compound Application, running spec.

Environment: Test Load Envelope/ cycling, SLE, Failure Points, Temperature

Design: Test to Dimensional, Makeup, and Load ExtremesDatabase Provides Dimensional specifications.

Run Per Specification, within Service Load EnvelopeQualification has Eliminated Failures!
