SCOPE / LIMITATIONS

This document provides guidelines for the assessment of erosive wear in piping systems associated with production and transportation of oil and gas and injection of water and gas into the reservoir.

Guidelines are given both as:

1) Limit states of fluid parameters and material grades which will not result in erosive wear

and

2) a recommended procedure for calculation of erosive wear in fluids containing sand particles.

The document provides procedures for calculation of erosion rate for typical components in a pipe and gives advice regarding erosion control and quantitative assessment of erosive wear.

The recommended calculation procedure is not applicable to certain components with highly complicated flow geometry; including manifolds and chokes. I.e. the models do not take into account upstream history effects.

The document does not address corrosion, erosion-corrosion or inhibitor selection and performance. However, for conditions/systems where specific velocity limits are given in the literature, these are referred.

Erosion of organic and ceramic coatings as well as metallic hard-facing coatings or other surface treatment is not covered by this document. Cavitation is briefly addressed where this is assessed to be a potential problem.

Droplet erosion is briefly addressed where this is assessed to be a potential problem and appropriate velocity limits are given.

Other aspects influencing on pipe dimensioning, flow rate limitations and pipe performance such as pressure drop, vibrations, noise, insulation requirements, hydrate formation, wax deposition, sand accumulation, severe slug flow, terrain slugging, pipe wall thickness estimation, pipe installation limitation/requirements, up-heaval buckling, etc. are not covered by the present document. However, for conditions/materials for which erosive wear will not be limiting with respect to pipe dimensioning or flow rate, other possible limiting parameters will be notified.
