Manifold assembly for delivery of fracture fluid

A method of pressurizing fluid from a low-pressure source with one or more fracturing pumps for delivery to a high-pressure destination, the method comprising:

• receiving the fluid at low pressure from the low-pressure source;
• controlling communication of the fluid to a pair of first conduits supported on a chassis by controlling communication of the fluid between the pair of the first conduits using a first header valve disposed between a pair of first header chambers, each first header chamber being connected to one of the first conduits;
• controlling communication of the fluid from at least one of a plurality of first outlets spaced along a first length of the first conduits, each of the first outlets being supported together on the same chassis and being configured to deliver the fluid at low-pressure to a corresponding one of the one or more fracturing pumps;
• receiving the fluid at high pressure from at least one of the one or more fracturing pumps at at least one of a plurality of second inlets of a second conduit supported on the chassis, each of the second inlets being supported together on the same chassis and being configured to receive the fluid at high-pressure;
• conveying the fluid along a second length of the second conduit to a second outlet configured to deliver the fluid at high-pressure to the high-pressure destination;
• and
• controlling communication of the fluid to a pair of third conduits supported on the chassis by controlling communication of the fluid between the pair of the third conduits using a second header valve disposed between a pair of second header chambers, each second header chamber being connected to one of the third conduits.

A manifold assembly connectable to fracturing pumps that pressurize fluid from a low-pressure source for delivery to a high-pressure destination, the assembly comprising:

• a first chassis having a length;
• first conduits supported on the first chassis and disposed along the length, each of the first conduits having a first inlet and having a first outlet, each of the first inlets being configured to receive the fluid at low-pressure, each of the first outlets being configured to deliver the fluid at low-pressure;
• a first header having at least one first header inlet configured to receive the fluid at low-pressure, the first header having a first chamber in fluid communication with the first inlet of a first of the first conduits, the first header having a second chamber in fluid communication with the first inlet of a second of the first conduits;
• a first header valve interconnected between the first and second chambers and being configured to open and close fluid communication between the first and second chambers;
• a second header having at least one second header inlet configured to receive the fluid at low-pressure, the second header having third and fourth chambers, the third chamber connected in fluid communication with a third of the first conduits, the fourth chamber connected in fluid communication with a fourth of the first conduits;
• a second header valve interconnecting the third and fourth chambers of the second header together;
• and
• a second conduit supported on the first chassis and disposed along the length, the second conduit having at least two second inlets and having a second outlet, each of the at least two second inlets being configured to receive the fluid at high-pressure from one of the fracturing pumps, the second outlet of the second conduit being configured to deliver the fluid at high pressure to the high-pressure destination.
