Erosion behavior of steel pipes carrying of some Iraqi crude oils

Abstract EN

This paper deals with erosion that is defined as a process of progressive removal of material from a target surface due to repeated impacts of solid particles for the special case of two phases (liquid and solid).

Experimental investigation dependence on erosion rate in different Iraqi oils obtained from Baghdad East Field (Al-Khaseb oil (Kh) and Al-Tanoma oil (T)) and from Al- Durra Refinery (Al-Stratege oil (ST)).

The effect of impact angle and testing time on erosion rates has been analyzed.

An erosion devise is fabricated and special fixtures have been developed to conduct erosion tests at various impact angles (30°, 45°, 60°, and 90°).

Experiments have been conducted in oil in absence and presence sand of concentration (1.74 wt.

%) with three particle sizes (600 μm, 850 μm and mixture of two) at the velocity of (8.4 m/s).

The results indicated that the increasing of impact angle led to decreasing erosion rate.
