Aspects of the present disclosure relate to connection blocks and pump manifold systems, and related methods, for pumping operations (such as frac operations). In one implementation, a connection block for disposition along a pump manifold of a pump system includes a first end hub having a first tube and a first outer shoulder extending outwardly relative to the first tube. The connection block includes a second end hub opposing the first end hub. The second end hub has a second tube and a second outer shoulder extending outwardly relative to the second tube. The connection block includes one or more faces between the first end hub and the second end hub.

A coupling element for a sterile flange connection for connecting fluid channels, comprising a fluid-contacting surface, a first opening end and a second opening end of the fluid-contacting surface, a flange part at the first opening end and/or at the second opening end, a connection plane, the connection plane being arranged normal to an axial coupling element axis of the coupling element and occluding the respective opening end of the coupling element in a delimiting manner, and a film, the film closing at least the first opening end of the fluid-contacting surface, with the coupling element comprising at least one film holding element separate from the coupling element and comprising a film-contacting surface to which the film is removably connected.

An improved rotatable joint for fluid flow therethrough having (a) a housing, (b) a tube fitting axially aligned with the housing, (c) a bearing around the tube fitting and configured to permit relative rotation of the housing and tube fitting, and (d) a seal between the housing and tube fitting, the improvement wherein (i) the housing includes one or more leak detection ports and (ii) the rotatable joint is configured such that any leakage of fluid through the rotatable joint flows first around the seal to the bearing and then through one or more of the leak detection ports to the atmosphere.

A vacuum pipe connecting member for detecting in real time a gas leak from a pipe connection between vacuum pipes is provided. In one aspect, the vacuum pipe connecting member is provided to include: a clamp for connecting a vacuum pipe to another vacuum pipe or to a semiconductor manufacturing apparatus; and a reactant that is provided in the clamp and is chemically reactive to a gas leaking from the pipe connection.

A sanitary clamp with facing ring halves employs one or more threaded closure devices configured to avoid having any threads exposed to the ambient. A bolt member may have a stepped shaft with a first smooth shaft portion and a male-threaded tip portion. The latter may be the same or a smaller diameter. An associated nut member has a blind bore that extends from a first end of the nut, with a first smooth wall portion and a second female threaded bore portion. The second female threaded portion may have the same bore diameter, or the bore can have a stepped interior diameter with the second female threaded bore portion having a diameter smaller than the first smooth wall portion. A seal member or gland within the smooth wall bore portion closes off a space defined between said the tip portion of the bolt member and the female-threaded bore portion. Once installed, there are no threaded surfaces of the bolt member or the nut member that are exposed to the ambient.
