Hot Rolling Coil Technology Development for Pipes Intended for Extraction and Transportation of Petroleum Products

摘要

A technology has been developed for the production of low-carbon and microalloyed steel for the production of strips in order to manufacture medium-diameter pipes for the extraction and transportation of petroleum products, and it allows stable corrosion properties to be obtained, according to the NACE TM 0284 technique, in a hot-rolled condition from slab with thickness of more than 200 mm. which is very difficult in terms of ensuring the availability of inclusions and heterogeneity in the structure. The obtained results allowed, with minimum costs, to prepare the previously developed integrated computer model (STAN 2000) for calculating the structure and mechanical properties.
