A fitting for an excavating apparatus can include a cylindrical pipe that can include a first metal material. In an example, the fitting can be configured for coupling to a hose. The pipe can include an interior surface and an exterior surface. Optionally, a perimeter of the pipe does not exceed a diameter of a first end of the pipe. The fitting can include a cladding layer (e.g., a second metal material) that can be coupled to the first metal material within the interior surface of the pipe. The cladding layer can include an abrasion-resistant material. The cladding layer can be coupled to the pipe such as with a welding operation. The cladding layer can include one or more ridges. The cladding layer can corregate the interior surface of the fitting and exterior surfaces of the fitting which can come into contact with abrasive material.

A valve block may have a cross-drill intersection bore formed within the valve block by a first flow bore intersecting a second flow bore. Additionally, at least one insert may be within the first flow bore or the second flow bore. The at least one insert may include a wall contacting an inner surface of the first flow bore or the second flow bore, a passageway defined within the wall and having openings at opposite ends of the insert, and a plurality of vanes extending from an inner surface of the wall into the passageway. The one of the opposite ends of the at least one insert may align with a surface of the cross-drill intersection bore. The at least one insert may reduce and/or protect the bores within the valve block from erosional damage

A pumping system for pumping a fluid for a wellsite. The pumping system includes a manifold assembly and pumping systems in fluid communication with the manifold header. The manifold assembly includes a manifold header that includes a manifold header body and outlets. The manifold header body includes an inlet to receive the fluid and an interior bore. Each outlet includes an entrance section shaped to have a profile that is approximately the same as a profile of an inner surface of the manifold header body, an outlet port shaped to flow the fluid approximately perpendicular to a longitudinal axis of the manifold header body, and a transition section shaped to have a radius of curvature that transitions from the profile of the entrance section to the outlet port and reduces internal erosion of the outlet due to the fluid flowing from the manifold header and through the outlet port.

Fracturing fluid delivery systems having components with sacrificial liners or sleeves are provided. In one example, a fracturing system includes a flexible fracturing fluid conduit coupled to a wellhead assembly. The flexible fracturing fluid conduit includes a flexible body, a rigid end joined to the flexible body, and a bore extending through the flexible body and the rigid end for conveying fracturing fluid to the wellhead assembly. The flexible fracturing fluid conduit also includes a rigid sacrificial sleeve installed in the rigid end and within the bore. In another example, a fracturing system includes a fracturing fluid delivery apparatus coupled to a wellhead. The fracturing fluid delivery apparatus includes a pressure-containing component having a rigid body with a bore for conveying fracturing fluid. The pressure-containing component has a sacrificial liner provided through the bore along an interior surface of the rigid body. Additional systems, devices, and methods are disclosed.

This disclosure describes a reinforced thermosetting resin piping system that is protected from external impact and UV damage by an outer polyurea-based layer. The embodiments described herein can be favorably used for underground and aboveground applications. In some implementations, an RTR pipe includes a core layer that includes a resin and fibers, an outer layer that includes a polyurea-based layer, and an interface layer between the core layer and the outer layer. The methods described herein also outline the process of producing the pipe structure.

A rope edge protection system having a rope protection mat and an edge protection mat in combination for the protection of rope. The rope protection mat is a generally rectangular sheet that can be secured in a sleeve-like configuration around a climbing rope and move along the rope with the user. The edge protection mat is a generally rectangular sheet with loops on each corner, but not limited to the corners, to secure the sheet in place against a building or other structure. The edge protection mat is a multi-layer sheet with a high loft layer to decrease the bend radius of the rope across a ledge. Both the rope protection mat and the edge protection mat include visual safety indicators.
