BACKGROUND

Field

Embodiments described herein generally relate to a system for connecting fluid conduits, valves, and the like.

Description of the Related Art

The connecting of fluid conduits may be achieved by engaging threads of one conduit with corresponding complementary threads of another conduit. An alternative to a threaded connection is a bolted flanged connection. Some fluid conduit systems, such as those used for well treatments in the oil and gas industry, are used temporarily in a series of different locations. These fluid conduit systems are successively assembled at a work site, used to convey fluids, disassembled, transported to another site, reassembled, and so on. It is desirable for the connections of such systems to be robust and reliable, yet facilitate rapid assembly and disassembly.

SUMMARY

The present disclosure generally relates to a fluid conduit connection system, and to fluid conduit systems that include connectors of the fluid conduit connector system.

In one embodiment, a fluid conduit system includes a trunk line and a manifold header coupled to the trunk line. The manifold header has a first bore in fluid communication with the trunk line and a second bore intersecting the first bore. A first manifold valve is coupled to the manifold header. A second manifold valve is coupled to the first manifold valve. A fracture header is coupled to the second manifold valve. A plurality of connection rods is coupled to the manifold header and to the fracture header. Each connection rod extends through a corresponding hole in the first manifold valve and a corresponding hole in the second manifold valve.

In one embodiment, a fluid conduit system includes a trunk line having a trunk line throughbore. A manifold header is coupled to the trunk line. The manifold header has a first bore in fluid communication with the trunk line throughbore and a second bore intersecting the first bore. A first manifold valve is coupled to the manifold header. The first manifold valve has a first manifold valve throughbore and an array of holes positioned about the first manifold valve throughbore. A second manifold valve is coupled to the first manifold valve. The second manifold valve has a second manifold valve throughbore and an array of holes positioned about the second manifold valve throughbore. A fracture header is coupled to the second manifold valve. The fracture header has a first array of fracture header holes. A plurality of connection rods is coupled to the manifold header and to the fracture header. Each connection rod extends through a corresponding hole of the array of holes in the first manifold valve and a corresponding hole of the array of holes in the second manifold valve.

In one embodiment, a method of performing a well treatment operation, includes flowing a treatment fluid through a first fracture valve, a second fracture valve, a flow spool, and a third fracture valve into a well. A plurality of connection rods extends through the first fracture valve, the second fracture valve, and the flow spool into the third fracture valve. The third fracture valve is coupled to a fracture header by a flange. The method further includes ceasing the flowing of the treatment fluid, closing the third fracture valve, flowing fluid out of the well through the first fracture valve, the second fracture valve, and the flow spool, and removing the fracture header from the third fracture valve.
