Understanding Exposure Temperature in NACE MR0175/ISO 15156-3:2009(E)

If you’re working in the oil and gas industry, you may have come across NACE MR0175/ISO 15156-3:2009(E), which sets out requirements for materials used in sour service environments. One key term in this standard is “”exposure temperature,”” but what does it mean?

The Meaning of Exposure Temperature

According to Clause 5 of NACE MR0175/ISO 15156-3:2009(E), “”The equipment user shall define the exposure temperature.”” This means that it’s up to the user to determine the temperature at which the material will be exposed to sour service conditions.

It’s important to note that exposure temperature refers to both design and operating temperature. In other words, the material must be able to withstand the temperature it will be exposed to during normal operation, as well as any temperature spikes that may occur during startup or shutdown.
