When you talk about "Sweet" and "Sour Service" in selecting materials you refer to: "Sweet" a service with no H2S and corrosion is mainly due to CO2. "Sour" a service with H2S content above the threshold defined by ISO 15156 / NACE MR 1075. The limit for carbon steel is 3 millibar of H2S (partial pressure of …
WitrynaNACE MR0175 Pipe and Fittings. Steel pipe and related fittings which are made from the NACE material (complied with NACE MR 0175 or ISO 15156 standard). We call them NACE pipe, or NACE pipe fittings. Therefore, these products are specially used in the oil and gas environments that contain the H2S etc corrosive chemicals. Witrynalevel of corrosion rate of typical carbon steel i.e. API 5L X-52 occurred in natural gas pipelines due to the effect of dissolved CO2. From the experiments obtained that corrosion rate of steel in environments containing CO2 ranged between 15-28 mpy. This high corrosion rate observed could severely damage natural gas transmission …

WitrynaCorrosion criteria based on laboratory tests are commonly expressed in grams per square meter per hour. For all metals this entity corresponds with approximately mm/per year (1 g/m²h = 1,1 mm/year) because the specifi c gravity (7.7 to 8.1) for all metal is similar. Titanium has a specifi c gravity of 4.5 the entity is 1g/m²h =1,9 mm year.
