The following are some application cases of duplex steel tee in petrochemical field:

Offshore oil platform: 2205 duplex steel seamless tee fittings of DN200 are used in the water injection pipeline of an offshore platform. Under the environment of 25MPa working pressure and seawater containing chlorine ions, the fittings remain intact after 5 years of operation, and the wall thickness reduction is less than 0.1mm, which is far better than the traditional 316L material. In the crude oil treatment system of FPSO (Floating Production Storage and Offloading Vessel), 2205 duplex forged tee fittings successfully solved the problem of stress corrosion under the environment of H₂S acidic medium, and improved the safety and service life of the system.
Refining device: In 2003, PetroChina in Khartoum, Sudan, 1.2 million tons / year coking gas, diesel hydrotreating unit of the reaction product water cooler (E-72104) tube bundle selection of super duplex stainless steel, which involves the application of duplex steel tee fittings, effectively solved the corrosion of the equipment in the corrosive media containing chlorine and other corrosive media environments.
Chemical piping system: in some chemical processes, the pipeline to transport fluids containing chlorides, sulfides and other corrosive substances, SAF2507 super duplex steel tee fittings can be manufactured in this harsh chemical environment to maintain the integrity of the pipeline, to avoid leakage accidents caused by corrosion.
