Part of:

During production of pipes for Oil Country Tubular Goods (OCTG) applications, the material is subjected to quench and tempering heat treatment in order to maximize the toughness for a given mechanical resistance, as well as adding resistance to cracking to hydrogen when exposed to H2S containing environments. The process of quench and tempered is controlled in order to maximize grain refinement and in some cases this requires a double quench and tempered. This is a costly process that requires optimization in order to maximize the product performance while minimizing production cost. In this work we worked with Saarland University for characterization of crystallographic grain size for different process conditions.
