System for reducing vibrations in a pressure pumping fleet
The present technology provides an electrically powered hydraulic fracturing system having pumps for pressurizing fracturing fluid, piping for carrying fracturing fluid, and vibration reducing equipment for use with the piping. The vibration reducing equipment includes helical coils that support the piping. The coils are made of a wire rope made of strands of steel cable twisted together. Grooved fittings are provided on some piping connections, and which allow pivoting between adjacent fluid conveyance members. Swivel joints are strategically located in the piping which allow rotational flexing between adjacent sections of the piping; thereby attenuating vibration in the piping but without stressing the piping.
1. A hydraulic fracturing system for fracturing a subterranean formation comprising:
an electrically powered fracturing pump having a discharge side;
a discharge branch of piping having therein pressurized fracturing fluid supplied from the fracturing pump; and
swivel connections strategically located in the discharge branch of piping, so that when pressurized fracturing fluid flows through the discharge branch of piping, a section of the discharge branch of piping is axially rotatable with an adjacent section of the discharge branch of piping.
2. The hydraulic fracturing system of claim 1 , further comprising at least one helical coil supporting discharge branches of piping at a strategically located position.
3. The hydraulic fracturing system of claim 1 , wherein at least one of the helical coils has an axis that is disposed oblique with an axis of an adjacent amount of piping.
4. The hydraulic fracturing system of claim 1 , wherein the fracturing pump is a first fracturing pump, wherein the discharge branches intersect with discharge piping that are in fluid communication with a second fracturing pump, and wherein the discharge branch intersections are at locations that are each spaced away from a surface on which the first fracturing pump is supported.
5. The hydraulic fracturing system of claim 4 , wherein the surface on which the first fracturing pump is supported comprises a trailer, truck, or skid.
