API 7-1 Oilfield Drilling Tool Saver Sub OD 187mm for Top Drive
Product Introduction
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 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.
Company Service
To supplement our range of Top Drive and Kelly Saver Subs, we introduced a range of Top Drive Saver Subs with Splined Design to suit the latest Top Drives on the market.
These subs and joints are all made from high quality grade, heat-treated alloy steel for maximum strength and durability, and threaded to customer specifications and API Spec 7-1 requirements.
