Drill Pipe Adapter – Custom Thread Adapter for Drilling Applications

Our drill pipe crossover subs are designed to connect drilling components with different thread specifications, providing a reliable transition between drill bits, drill pipes, and other drilling equipment. Also known as drill pipe adapters or thread crossover subs, these components help drilling operators configure compatible tool connections for different drilling applications.

We manufacture crossover subs in commonly used thread combinations, including Z42–Z50, Z50–2 3/8 REG, 2 3/8 REG–2 7/8 IF, and NC26–NC31. Custom thread configurations can also be discussed according to your equipment requirements and technical drawings.

Available material options include 40CrMo and 42CrMo alloy steel. The components undergo quenching and tempering heat treatment to improve strength, toughness, and resistance to wear under demanding drilling conditions.

As a drilling tool manufacturer , we support customized dimensions, thread combinations, and production requirements for drilling equipment distributors, drilling contractors, mining companies, water well drilling businesses, and industrial buyers.
