S-Pipe OEM Ref. 117063 – Evergrow Part #175595-7500 for NOV TDS-11SA Top Drive

The S-Pipe OEM Ref. 117063, supplied by Linhai Evergrow under Evergrow Part #175595-7500, is a key drilling-fluid flow component for the NOV TDS-11SA top drive system. This S-Pipe is identified as a right-hand (RH) weldment and is available in the 7500 PSI configuration for demanding oil and gas drilling applications. Evergrow's TDS-11SA parts information lists 117063-7500 as the RH S-Pipe weldment, with 175595-7500 as the corresponding Evergrow part number.

What Is the S-Pipe 117063?

The S-Pipe is part of the drilling-fluid circulation path within the top drive. It works together with the wash pipe assembly, S-Pipe adapter, mounts, service-loop components, and related connections to provide a continuous route for drilling fluid.

For the NOV TDS-11SA, the S-Pipe 117063 is listed alongside the 117063-7500 version, while other S-Pipe configurations include the left-hand 30114855 series and Hercules S-Pipe 116376. This makes accurate part-number identification especially important when ordering a replacement.

The S-Pipe is positioned in an area where reliable fluid containment is essential. During drilling, the circulation system must handle drilling mud under pressure while the top drive operates in a demanding mechanical environment. A suitable replacement S-Pipe helps maintain the intended connection between the top drive's fluid pathway and the wash pipe system.

S-Pipe 117063-7500 and Wash Pipe Connection

The 117063-7500 S-Pipe works closely with the wash pipe assembly OEM Ref. 30123290, which is another important component in the TDS-11SA fluid circulation system. Evergrow's product information describes the wash pipe assembly as being located between the S-Pipe and main shaft, providing the connection required for drilling-fluid circulation.

7500 PSI S-Pipe for TDS-11SA

The 117063-7500 designation identifies the 7500 PSI version of the RH S-Pipe weldment. Compared with the standard 117063 configuration, the 7500 PSI version is an important option for applications where the fluid system requires the corresponding pressure-rated configuration.

Because S-Pipes are exposed to drilling-fluid pressure, vibration, connection loads, and harsh operating conditions, regular inspection is recommended. Maintenance teams should pay particular attention to the weldment, connection areas, mounting points, sealing surfaces, and adjacent fittings.

Signs that an S-Pipe may require replacement can include:

· Visible cracking or deformation

· Leakage around connections

· Damage to the weldment

· Corrosion or severe surface deterioration

· Abnormal wear around mounting points

· Evidence of pressure-related damage

Any component showing significant damage should be evaluated by qualified maintenance personnel before the top drive returns to service.
