API New Working Item

Develop C125 DCB Acceptance Criteria

2

Rational• Increasing demand for high strength C125

in deep water applications.

• No API and ISO specifications for C125

• Only Method A test acceptance criteria in vendor’s product specification. No Method D acceptance criteria.

NACE TM 0177 Method A (pH3.5, PH2S = 0.5 psi, 24C, and 85% SMYS applied stress)

3

Proposal• Adopt similar testing approach of current

API C110 program 2318A. Select 5 pipes and MTRS from 3 manufacturers.

Select three arm displacements.

Test solutions: NACE B and D.

Test durations: 14 days for Solution B and 17 days for Solution D ?
