Principle and Exemplification of the Direct Assessment on the Internal Corrosion of Dry Gas Pipeline
摘要
Abstract
The basic ideas of dry gas-intemal corrosion direct assessment (DG - ICDA)is to predict the most likely locations for liquid accumulation by using multiphase flow modeling to calculate the critical inclination angle, and it inspected corrosion situation of these locations, and then extrapolated corrosion situation of other parts in pipeline. Meanwhile,it analyzed basic principle of DG - ICDA, expatiated 4 steps of this method. DG - ICDA not only can be used alone as a main assessment method for internal corrosion,but also used as an auxiliary tool for intelligent pigs and pressure testing, this will improve the technology level of integrity management for long-distanco natural gas pipeline.关键词
