Recommended grease for straight threads (stub acme)

Recommended grease for straight threads (stub acme)

(OP)
Are you stub acme threads to make up most connections on my tool designs. These are downhole tools used in oil and gas wells. I had been using high temperature seal Grease. I torque the outer connections to 10,000 foot pounds do you prevent the tool from backing off while running in the hole with pipe. The tools remain in the hole and I do not have to back the connections off. Seals are also used these connections so I use the Heitkamp seal Greece as a lubricant to prevent galling.

The material is low alloys steel 110 KSI mys 36 Rc hardness.

Is this acceptable or would you recommend a different thread grease? Where could I go to find the appropriate grease for this application?

RE: Recommended grease for straight threads (stub acme)

I've found anti-seize compounds are better at preventing galling of threads than any grease that I've seen. Particularly on materials like stainless steel.
Bostik make a product called 'Never-Seez', I'm sure that there are many others.

Gear cutter,

Do you know if these compounds contain lead? Are they compatible with HNBR AND VITON?
