Seamless Wellhead Fittings API 16C Integral 4 Inch Straight Pipe / Tubes
Wellhead Fittings API 16C Integral Straight Tubes Alloy Steel Forging
The high pressure straight tubes with the weco union connection is wellhead Chiksan integral Pup Joints, it is used to transporting high pressure flow in wellhead manifold such as cementing manifold, fracturing manifold, maintenance manifold and oil well testing manifold.
The Integral straight tubes are made of alloy steel forging, which make it feature with reliable and long service life.
Features of Integral pup joint / Integral straight pipe
* Integral pup joints are designed with integrally constructed, forged ended, and seamless upset construction.
* The weco union end connections of integral pup joint enable fast, easy make-up and break-out of temporary flow lines.
* The Integral pup joints are hydrostatically tested at 1.5 times the rated cold working pressure.
* Uniform bore for greater flow capacity.
* Eliminates all welds or threads.
