API Non magnetic Drill Pipe Pup Joints for Oil & Gas Downhole Drilling
Pup Joints are commonly used to adjust the length of the drill string to the elevation of rotary table for easy surface handling and drilling practices. They undergo the same stresses as drill pipe and their performance depends primarily on their superior mechanical properties.
All of our API Non magnetic Drill Pipe Pup Joints are made of a kind of low carbon high chrome-manganese alloy steel, which is refined after strict chemical composition ratio and forged to achieve its mechanical properties, to make sure superb mechanical properties of low permeability and high strength. Mainly used for down hole directional drilling.
Our API Non magnetic Drill Pipe Pup Joints are available in 5’, 10’, 15’ and 20’ lengths and can be ordered to match standard drill pipe dimensions. The primary use of the pup joints is to adjust the overall length of the drill string to land at a specific depth while staying within the working area of the Kelly.
