1- Model of BOP
2- Bore (Internal Diameter)
3- Working pressure: the maximum wellbore pressure, the ram can shut in and seal around.
4- Temperature class: surface temperature the ram can withstand and have the same properties.
5- Date of manufacture
6- Rated control pressure: the hydraulic control pressure supplied to the ram from Accumulator unit.
7- Recommended operating pressure: the range of closing pressure from Accumulator unit needed to close the ram around the pipe and seal.
8- API Monogram:
Indicates that ram manufactured in conformance with the relevant API product specifications (API Spec 16A for drill-through equipment)
9- Trim H2S: indicates that internal components—such as seals, rams in contact with well fluids—are specifically designed and manufactured for environments containing hydrogen sulfide (H2S)
10- Assembly weight and dimensions: for lifting plan and BOP crane load test.
