US Patent 11486240 Manifold header for use at a wellsite

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.
