Tubing Swage

I. Introduction

Tubing swage is a tool to shape the changed diameter of  to guarantee that the downhole device can pass smoothly or to get through the flavedo-type blocks at the end of tubing. 

II. General Technical Parameters

Note:more customized parts are available upon request.

III. Structural Features

The top of the tubing swage has external threads (or quick male joint) and fishing neck; the inner diameter of waist is about equal to that of the deformed oil pipe, so there are air holes or drain holes in the middle, and the pipe tapers off from the middle to both ends; the bottom also can be processed with threads to connect with tools.

The whole body of tubing swage is made of alloy steel, and the hardness of the part for shaping reaches 43~45HRC through quenching and tempering. 

IV. Method of application

Connect the tubing swage with the bottom of jar. When the tubing swage is lowered to the area of changed diameter of oil pipe and cannot go down, it can enlarge the diameter though downward jarring so as to guarantee that the downhole device can pass through smoothly.  

V. Notes

The tubing swage is only used to shape the area of changed diameter of oil pipe. When the pipe is deformed seriously, other tools shall be considered, and it also cannot hit the thick obstruction in the oil pipe.
