Dear sir,, Drifting is the process in which a pipe is checked internally to verify that the Inner Diameter of the pipe is within the specifications as laid down by the American Petroleum Institute (API). This is to ensure that when the actual drilling operations are carried out , specified size drill bits and instrumentation will go through the line. The process involves the passing of a Machined mandrel through the pipe with it's diameter in conformance with specifications as laid down by end-user. The length of the mandrel is also specified. This would ensure that the inner diameter is at least bigger than or equal to the specified inner diameter and any bends on the pipe would not cause jams. This also eliminates casing which would have got mashed due to handling or transportation. Thank you
Good job, where location a maked job?
Hululais sir,with my teacher mr sujito 😁🙏
