Abstract:

Article Preview

This document demonstrates CTOD (crack tip opening displacement) tests at0°Cof welded joint in X80 marine drilling riser in accordance with the BS 7448 standard. The three point bending specimens are made in the weld center line and heat affected zone for the butt-welded joint in Φ533×25.4mm X80 marine drilling riser respectively according to the requirement of the standard. The CTOD testing results are discussed in detail, which can provide the basic to evaluate and optimize the welding and heat treatment technology of marine drilling riser.
