Fracture control plan
Fracture control plan
(OP)
If one have to carryout fracture controll plan for 40 years old gas pipe line what methods use to address the issues related to interaction with weld heat effected zones, considerations for corroded pipe etc. For a newly fabricated pipes sample testing is a possibility where as old corroded pipes should have some procedures to incorperate these issues to the plan.Appreciate your feed back on this subject.





RE: Fracture control plan
A line 40 years old may have a large range of toughness properties. First stop is to look at the original material certificates as perhaps some toughness data will be present on them.
Gas pipelines on land do not require a fracture control plan for girth welds. Fracture control plans normally refer to pipe base metal toughness properties. If however, you now find a concern over displacement like seismic, girth welds could be a problem.
