Title of the lecture |
Tubular Products for Oil and Gas Industry Application
|
Summary of the spoken topic |
|
The pipes sector is essential for the oil industry. It´s through pipes and ducts that all the flow is done, and all the oil industry related existing process is established. The piping is considered the veins of the oil industry. The major challenges to the oil and gas industry are the exploiting in arctic environments and deep waters (over 500 m) and ultradeep waters (over 1000 m), for in these environments we need high mechanical strength and high tenacity to low temperature. Potential materials for these application scenery are the high strength and low alloy "HSLA". These HSLA steels are the raw material for pipes that can be manufactured through an integrated system, in the case of seamless pipes, or through a half-integrated system in the case of "Welded" pipes manufacturing. In the integrated route the raw material is steel plants, sponge iron, which is solid, originated from direct reduction processes, as for example Midrex. The sponge iron is used as methalic load in the electric oven for the liquid steel production which receives the alloying from the alloys and chemical composition final adjustments in a secondary refinement station, as pan oven, for example. After the chemical composition adjustment, the liquid steel is taken to the ingoting for solidification on billet shapes. When leaving the steel plants the billets are reheated, around 1300 °C, for the starting of the seamless pipes manufacturing. In the semi-integrated route, we have pig iron as steel plants raw material. It is liquid, originated from the high ovens. After a pre-treatment, pig iron is used as a metallic load in the LD converters for liquid steel manufacturing. The alloying of the alloys takes place in the liquid steel leaking from the LD to the pan. Where the known pan oven, or another secondary refinement station such as CAS-OB e RH are responsible by the chemical composition final adjustment. After the secondary refinement, the steel goes to the plate continuous ingoting. These plates are then directed to the thick plates laminating line, or hot strips laminating line, where the laminating final products steel plates or coils, respectively. These steel plates or coils are then sold by the iron and steel industries to the welded steel pipes manufacturers. The tubular products are standardized by different rules, where the most known at the oil and gas production and flow segments are: API 5L, ISO 3183, DNV OS F101 and DIN 17172 (conduction pipes), API 5CT and ISO 11960 (production pipes). Thus, this speech has as objective to show the main metallurgical characteristics of the raw materials and of the seamless and welded popes manufacturing process, as well as these products major applications.

The pipes sector is essential for the oil industry. It’s through pipes and ducts
that all the flow is done, and all the oil industry related existing process is
established. The piping is considered the veins of the oil industry. The major challenges
to the oil and gas industry are the exploiting in arctic environments and deep waters

need high mechanical strength and high tenacity to low temperature. Potential materials

HSLA steels are the raw material for pipes that can be manufactured through an integrated
