Abstract: 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.

Abstract: A double vented transition elbow can be used when venting a variety of applications, such as for baseboard heaters and hot water heating systems. The double vented elbow allows venting in one orientation or in a different orientation when the elbow is rotated. One end of the elbow couples to copper tubing, while the other end of the elbow couples to PEX tubing. Thus, the elbow not only allows for venting in two different orientations, it also allows for the transition from copper to PEX tubing within the same fitting.
