I am looking at some mechanical testing of a pipeline welding procedure. Part of the qualification programme involves fracture mechanics testing such as CTOD-R or J-R (SENT) tests. I am familiar with these and the information that they provide.
However there is also reference made to a test...
I've been asked to perform a failure assessment on some failed armour wires from a subsea rov umbilical.
I am told that the material is galvanised GIPS steel. Of course no material specification given - that would be too easy!!
Can anyone enlighten me on what GIPS stands for?
Thank-you very much - that really helps me!
For info - its Incoloy 825 and Inconel 625...slightly different alloys. Incoloy 825 has higher Fe and is stabilized with Ti. Inconel 625 is NiCrMo alloy stabilized with Nb. Incoloy 825 is softer and is typically what we specify for gaskets against...
Are there any hard and fast rules as to the extent of corrosion resistant alloy weld overlay required on subsea flange faces? I am in a debate about whether only the ring groove should be overlaid or if overlay of the full flange face is required. The overlay alloy would be Alloy 625.
The...
