Main Objective

The development of the "Soft Crack Arrestor" validated design procedure will allow this device to be used for a wide variety of natural gas and liquid CO2‚ pipeline projects. This device will reduce the risk associated with catastrophic fracture of large-diameter natural gas or liquid CO2‚ pipelines.

Public Abstract

This testing will be done over a range of temperatures to cover extreme conditions for future pipeline designs. It is also essential to develop this data at the loading rates that arrestor will experience during a crack arrest event. With the material property data, the Engineering Mechanics Corporation of Columbus crack arrestor design criterion will be used to design arrestors for subsequent full-scale validation tests in a Phase II effort. Engineering Mechanics Corporation of Columbus also has the only high-energy full-scale burst test facility in North America for conducting large-diameter pipe fracture and crack arrestor experiments.
