Tubing Hanger and Packoff Running Tool

JHWC · Apr 12, 2015

Hi All,

As I check the Engineering Database Standard for the surface product (tubing hanger) in oil and gas, it is stated with the following

Body + ACME thread --> Nitriding + Xylan

Does this mean that the body of the tubing hanger undergo nitriding process while the acme threads undergo xylan coating?

Or both the body and acme threads undergo nitriding and xylan coatings?

Please kindly advise.

Thanks,
Jeffrey

I see no problems with both being done.

Hi Jbeckhou,

I was told by a principle engineer that the coating is done separately. Therefore, I am not sure what should be technically right?

The engineering data here in this case is misleading.

In technical prospect, it is done separately.

I am assuming that in theory, it can be done together.

Thanks,
Jeffrey
