Integral pup joints are components that transport high-pressure fluids in cementing and fracturing units. They are widely used in acidic operating environment (excluding operating environment containing sour gas, such as CO2 and H2S) in high pressure discharge line, input line, temporary flow line, well testing line, and other high-pressure transmission line.

The technical parameters and performances of the integral pup joints comply with the API 6A specification.Their product specification level is PLS3 and performance level is PR2. They are interchangeable with similar products of SPM.

The integral pup joints are made of high-strength alloy steel and are manufactured by a special toughening process.They use Acme threaded connection, which makes them easy and fast to disassemble,while providing firm and reliable connection.Multiple sealing designs and extremely high machining accuracy ensure the sealing performance of the integral pup joints.
