Provided are an installation method and an installation device for a fluid control device capable of improving controllability of a fluid in a pipe by improving positional accuracy of a valve body inserted into a hole formed in a fluid pipe in a housing and decreasing the size, weight, and cost of construction equipment such as an operation valve device or an installation device of a fluid control valve.

A proofing air jet having a hollow elongated body having an air outlet and a suction inlet, the air outlet opposing the suction inlet, a pressurized air inlet into the body between the air outlet and the suction inlet, the pressurized air inlet being angled with respect to the hollow elongated body to flow pressurized air in a direction from the pressurized air inlet to the air outlet and provide a suction at the suction inlet, the air outlet having an innerduct/microduct connector for connecting to an opening of the innerduct/microduct, and the suction inlet having a string inlet configured to accept string. A plurality of the proofing air jets can be connected to a manifold.

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.

A pipe coupon extraction tool includes: a rod defining a first end, a second end, and a central axis; and a spring bar defining a first end and a second end, the spring bar rotatably secured to the rod, a surface of the spring bar configured to be angled with respect to the central axis when the pipe coupon extraction tool is engaged with a pipe coupon.

A system for filling multiple sterile containers includes a filter with an inlet port and multiple outlet ports, the outlet ports being pre-attached to sterile containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines are connected to a respective container interior. The respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. A container that is connectable to an outlet port the system has a bladder, a first tube and a second tube connected to the bladder, and a sterilizing filter. The container, the first tube and the second tube, and the sterilizing filter are sterile before water is flowed through the sterilizing filter into the bladder.
