09364 Large and Small Scale SCC Testing of 316L Clad at 135 C

This work was undertaken to explore the possibility to extend the limits of 316L to higher temperatures.  The large scale test consists of a full ring pipe which is stressed externally and exposed internally to the test fluid.  The small scale tests are four-point-bend (4PB) tests in accordance with ISO15156-31 and EFC172.

Use of 316L clad pipes are currently limited to 120 oC to avoid stress corrosion cracking. This work was undertaken to explore the possibility to extend the limits of 316L to higher temperatures. The testing is divided into a large scale test and a small scale test. The large scale test consists of a full ring pipe which is stressed externally and exposed internally to the test fluid. The work has also investigated the relationship between the test methods. It is the intention to find small scale tests which gives similar results as the large scale test.

The small scale tests are four-point-bend (4PB) tests in accordance with ISO15156-31 and EFC172. The test specimens are made of approximately 3mm thick clad material where the carbon steel backing has been machined off.

The tests were conducted at 135 oC with a partial pressure of 0.02 bar H2S. CO2 pressure was approx 11 and 1 bar for the small and large scale test respectively. In situ pH was adjusted to approximately 5.3. Chloride concentrations were between 40.5 and 41.8 g/l Cl-.
