NACE International is an organization that develops and publishes standards and technical guidelines for various industries, including the oil and gas industry. NACE Fasteners are fasteners that meet the standards and guidelines set forth by NACE International. These fasteners are designed to withstand harsh environments and conditions, such as high temperatures, corrosion, and exposure to chemicals. They are commonly used in petrochemical processing, oil and gas production, and other industrial applications.
NACE International has published several standards related to fasteners, including NACE MR0175/ISO 15156, which covers the selection and use of fasteners in oil and gas production and processing. This standard specifies the materials, design, and testing requirements for fasteners used in these environments. NACE MR0103, another standard published by the organization, covers the corrosion resistance of fasteners used in sour service environments, which are environments where the presence of hydrogen sulfide gas can cause corrosion.
If you are looking for NACE Fasteners, it is important to make sure that the fasteners you purchase meet the relevant NACE standards and guidelines. This will ensure that they are appropriate for use in your particular application and that they provide the required level of performance and reliability.
