Pup Joint
Pup Joint Is A Special Type Of Oil Casing, We Can Understand It As A Short Length Of Oil Casing.
In An Oil Well Project, When Most Of The Tubing Is Laid In And Only A Few Meters Are Needed At The End, It Is Necessary To Use The Short Connection At This Time.
Generally Speaking, The Length Of The Short Connection Is 3 Feet, 6 Feet, 9 Feet, And 12 Feet. Its Buckle Type And The Petroleum Casing Can Be Consistent With Each Other, Often Purchasing A Batch Of Petroleum Casing Needs To Be Equipped With Some Short Pup Joint.
It Is A Flexible Product In Oil Exploration.
