Using its global network of threading facilities, Hunting can offer both premium and API connection threading machined onto manufactured and free-issue components.

Product summary

Hunting has established a global network of manufacturing facilities capable of machining Hunting Proprietary connections, API and licensed threadforms onto full length and accessory components from 1.9 inch to 20 inch OD.

Influenced by Lean Manufacturing and Six Sigma principles, Hunting’s facilities are organised in cellular processes, with separate threading lines for range 3 casing, tubing sizes, large diameter (up to 20”), dedicated pup joint and coupling manufacturing lines.
