Abstract
After 222 days of normal operation of dump flood system at a petroleum field, one of its blast joints, which are pin-box type, suffered leakage due to internal erosion damage at the joint threaded portion. The main problem was related to improper fitting of the blast joint due to unequal axial threaded distances of its pin and box parts. This improper fitting created severe turbulent flow condition and subsequently severe impact by water jets. In order to minimize such failure in the future, the fitting of the blast joint must be of a higher quality, which can be achieved by having equal axial threaded distances for its pin and box parts.
