which is the most frequently used test method for conducting SSC Test?
(OP)
Hello everyone
NACE MR 0175 is the standard for the materials resistive to Sulfide Stress Cracking in H2S environment and for conducting SSC test there are many methods like proof ring type, four point bend type and four point deflection type methods. I would be really glade if some tell me which is the most frequently used method for conducting SSC test.
Kind Regards

RE: which is the most frequently used test method for conducting SSC Test?
An example is for us, a large chemical plant, we we use bench scale testing to find a material that is suitable for the process. Once a material is determine we will run U-bend tests at various temperatures. At the same time we normally run heat-flux tests at the higher process temperature for corrosion and cracking on the test coupon. All these tests can only increase your confidence level but at time in-service cracking can still occur.

Keep in mind, though, the test method says nothing about what test reuslts are needed for any particular service. There are test parameters and results that can mean that mean under one set of conditions, the material will pass while another set of conditions, the material will fail, even for the same test. The test method, test parameters, and results all need to be carefully evaluated when deciding on how to qualify a material for a specific application.
