Description
Изобретение относитс к черной металлургии , в частности к эрозионностойкой стали, используемой дл работы на сточных водах, содержащих сероводород, при высоких скорост х перетока жидкости.The invention relates to ferrous metallurgy, in particular to erosion resistant steel used for work on wastewater containing hydrogen sulphide at high flow rates.
Цель изобретени - повышение эрозионной стойкости в водной среде, содержащей сероводород и ионы хлора.The purpose of the invention is to increase the erosion resistance in an aqueous medium containing hydrogen sulfide and chlorine ions.
Химический состав исследуемых сплавов и их эрозионна стойкость на сточных водах, содержащих сероводород приведены в таблице. Термообработка опытных сплавов осуществл етс по следующему режиму: нагрев до 1050°С, охлаждение на воздухе; нагрев до 750°С. охлаждение на воздухе; старение при 450°С в течение 2-3 ч, охлаждение на воздухе. Испытани на эрозионную стойкость осуществл ютс на месторождени х Башнефть, непосредственно в пластовых сточных водах, содержащих сероводород и ионы хлора. Давление жидкости , омывающей образцы при испытании.The chemical composition of the alloys under study and their erosion resistance on wastewater containing hydrogen sulfide are given in the table. Heat treatment of experimental alloys is carried out according to the following mode: heating to 1050 ° C, air cooling; heating to 750 ° C. air cooling; aging at 450 ° C for 2-3 hours, air cooling. Erosion resistance tests are carried out at Bashneft fields, directly in reservoir wastewater containing hydrogen sulfide and chlorine ions. The pressure of the fluid washing the sample during the test.
