Product Overview
Saver sub is 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 Top Drive Saver Subs serves as a sacrificial element between the drill string and Top Drive or Kelly, reducing any unwanted repair and maintenance costs.
Packaging Type
We can supply China made interchangeable parts for above mentioned Top Drive Parts. If you need any related parts or tools, freely ask me.
