BEIJING - Aug. 4, 2022 - PRLog -- Top Drive Subs serve as the sacrificial element between the drillstring and the top drive, reducing repair and maintenance costs. The Top Drive Sub can easily be repaired or replaced in the event the lower pin threads become galled or damaged. These tools are manufactured from selected bars of alloy steel, heat treated to provide the strength and toughness required to carry the entire weight of the drillstring. Top drive saver subs are manufactured to customers request, based on API requirements.  All of our drill stem subs are manufactured in accordance with API specifications.

Features and Benefits:

●  Heat treated to meet or exceed API specifications for drill pipe tool joint mechanical properties
●  Precision machined API connections, with proprietary connections available machined by licensed vendors
●  Serialized for complete material traceability

A short length of drill collar that has male threads on one end and female on the other. It is screwed onto the bottom of the kelly or topdrive and onto the rest of the drillstring. When the hole must be deepened, and pipe added to the drillstring, the threads are unscrewed between the saver sub and the rest of the drillstring, as opposed to between the kelly or topdrive and the saver sub. This means that the connection between the kelly or topdrive and the saver sub rarely is used, and suffers minimal wear and tear, whereas the lower connection is used in almost all cases and suffers the most wear and tear. The saver sub is expendable and does not represent a major investment. However, the kelly or topdrive component threads are spared by use of a saver sub, and those components represent a significant capital cost and considerable downtime when replaced.
