The design of sealing ring or gasket takes into account the harsh environment that may be encountered in geotechnical drilling operations, with good wear resistance, corrosion resistance and high pressure resistance, to ensure that the connection can still maintain good sealing performance under high pressure, high temperature, high humidity and other conditions, to adapt to the complex operating environment.

The special thread design and sealing performance optimization of R38 threaded coupling sleeve provide reliable connection guarantee for geotechnical drilling operations, and at the same time, it can effectively cope with the harsh operating environment and ensure the solidity and sealing performance of the connection, which provides important support for the safety and efficiency of drilling operations.

The T38 threaded coupling sleeve is a key component for geotechnical drilling operations:

Diameter size: The "T" in the T38 model number stands for the type of thread, while the "38" stands for the diameter size of the coupling sleeve. In this case, the T38 coupling sleeve has a diameter of 38 mm, which is an important feature to distinguish it from other types of coupling sleeve. The expansion of the diameter size helps to clarify the scope of application of the coupling sleeve and to match the specifications of the drill pipe.

Thread specification: The "T" in the T38 model number also represents the thread specification, which is usually matched to T38 threaded drill pipe. The expanded thread specification helps ensure a good fit between the coupling sleeve and the drill pipe, providing a solid connection and transferring torque to meet the demands of high-intensity drilling operations.

For this reason, T38 threaded coupling sleeves are type-expanded to include the diameter size and thread specification, information that is critical to the proper selection and use of the coupling sleeve to ensure optimum performance in the drilling operation.
