In various implementations, a hydraulic fracturing piping system may include one or more rotatable elbows to connect other components of the hydraulic fracturing piping system. Using rotatable elbows may facilitate connections in the hydraulic fracturing piping system. For example, when using a rotatable elbow, in the assembly of the system, the rotatable elbow may be capable of rotating to different positions to facilitate alignment of the hydraulic fracturing manifold and hydraulic fracturing stack (e.g., christmas tree), when the hydraulic fracturing manifold and the hydraulic fracturing stack are not in alignment. In some implementations, the elbow may include an internal radial transition (e.g., of approximately 90 degrees) to control the media being injected into the wellbore. The internal radial transition of the elbow may create a more uniform media flow and/or less turbulence, which may significantly reduce erosion of the inner surfaces the bore of the elbow.

A fracturing system (17) includes a fracturing spool (18) that mounts onto a wellhead assembly (10) for injecting fracturing fluid into a well (12) beneath the wellhead assembly (10). An isolation sleeve (42) is included with the fracturing system (17) that couples to the fracturing spool (18) and extends into the wellhead (10) to isolate and protect portions of the wellhead assembly (10) from the fracturing fluid. A seal (52) is between the isolation sleeve (42) and bore (49) of the wellhead assembly (10), which is threaded to the isolation sleeve (42). Manipulating the threaded connection between the isolation sleeve (42) and seal (52) selectively positions the isolation sleeve (42) to designated axial positions within the wellhead assembly (10).
