EPDECOM V2.0 pipeline fracture control software is designed to calculate the minimum linepipe toughness (arrest toughness) required to arrest a running fracture.

Fracture control is an important consideration in the design of steel pipelines. The conditions that cause a defect in a material to grow (rupture) and to stop growing (arrest) must be determined because steel pipelines are long, continuous structures, and therefore a crack can propagate for a long distance if it is not arrested. The material property of the pipe that defines how it will resist fracture is toughness. The tougher a pipe is, the larger the amount of energy required to create a crack is, and hence the greater is its tolerance to defects.

A generalised method for predicting the fracture propagation toughness requirement was developed by the Battelle Institute, called the Battelle Two-Curve Method (BTCM). In the BTCM, two equations are developed – the relationship between decompression wave-speed and pressure, and the relationship between fracture velocity and hoop stress. As each of these equations applies to a mixture and any number of initial conditions, many numerical computations are required which are best provided using a dedicated software package.

EPDECOM V2.0 is an implementation of the NG18 equations used in the original BTCM. It uses modern equations of state, in particular GERG 2008, to predict the decompression wave speed, providing better predictions of the toughness requirement than other similar software packages. Several correction factors are available in the software as required. EPDECOM is intended for use in assessing designs involving the transport of rich gas, complex mixtures and/or CO2 mixtures. One application of this is in the control plan against running ductile fracture (RDF) in API5L pipes used in high pressure transmission pipeline applications.

EPDECOM V2.0 is owned and distributed by Future Fuels CRC.
