Abstract

As a common oil well pipe material in the oil and gas industry, P110 steel is prone to erosion corrosion at high temperature, high pressure, and high salinity flowing media, which threatens the safety of oil and gas development.

Key words

P110 steel; erosion corrosion; high temperature and pressure; machine learning; random forest
