NACE MR0175 is the main material selection standard for upstream equipment and pipelines of hydrogen sulfide (H2S) oil and gas fields, including oil and gas field downhole facilities and surface facilities. This standard has been widely adopted and recognized by international oil companies and manufacturers. For the selection of surface engineering materials for oil and gas fields containing hydrogen sulfide (H2S), NACE MR0175 has gradually become a mandatory material selection standard.
In 2018, NACE International launched the NACE International MR0175 carbon steel certification and MR0175 corrosion-resistant alloy certification on a global scale. Comprehension of applicable boundaries of corrosion-resistant alloys, practical engineering applications, etc., and reasonable use of standards.
The American International Association of Corrosion Engineers was established in 1943. The purpose is to focus on corrosion engineering, corrosion investigation and research, and introduce the development of corrosion technology, set common industry standards, and devote itself to the dissemination and training of corrosion knowledge. It is the world's largest, influential and An authoritative anti-corrosion engineering organization, its corrosion standards and professional technical qualification certificates are widely recognized and adopted internationally.
NACE International Corrosion Conference is one of the largest corrosion academic exchange activities in the world. It is hosted by NACE International and held once a year. It is one of the most important activities in the field of international corrosion protection.
