In-service life estimation of damaged gas pipelines: Full-scale experiments and finite element analyses

In-service life estimation of damaged gas pipelines: Full-scale experiments and finite element analyses

Statistical analysis reveals that mechanical damage is the first cause of incidents on gas transmission pipelines. They can be created by third party activities such as excavator tooth impact or by interaction between the pipe and rocks. To manage the damaged pipeline safely without useless cost, t...
