Suction and discharge lines for a dual hydraulic fracturing unit
An electrically powered hydraulic fracturing system includes pumps for pressurizing fracturing fluid, piping for carrying fracturing fluid, and field connections in obliquely oriented segments of the piping. The connections are between lead lines that couple directly to the pumps and lines carrying fluid to and from the pump; and are assembled and disassembled in the field. Operations personnel can more easily manipulate connections that are obliquely oriented than those that are horizontal or vertical.
1. A hydraulic fracturing system for fracturing a subterranean formation comprising:
a plurality of electrically powered fracturing pumps mounted on a trailer, each of the plurality of electrically powered fracturing pumps attached to a corresponding first lead line and a corresponding second lead line;
wherein each of the first lead lines and the second lead lines are separate and apart from one another while on the trailer, each of the first and second lead lines comprising a main segment attached to at least one of the plurality of electrically powered fracturing pumps, and a tip segment that is angled obliquely to a portion of the main segment proximate the tip segment, wherein the tip segment of each of the first lead lines is angled differently with respect to the main segment than the tip segment of the corresponding second lead line, and wherein the main segment and the tip segment comprise a unitary pipe segment; and
flow lines in fluid communication with the lead lines.
2. The hydraulic fracturing system of claim 1 , wherein the tip segment of each lead line extends along an axis that angles away from a horizontal axis from around 22 degrees to around 45 degrees.
3. The hydraulic fracturing system of claim 2 , wherein the tip segment of the first lead line is oriented at an angle of around 22 degrees with respect to the horizontal axis, and segment of the second lead line is oriented at an angle of around 45 degrees with respect to the horizontal axis.
4. The hydraulic fracturing system of claim 1 , wherein the lead lines comprise suction lead lines, the system further comprising discharge lead lines that extend along paths that are generally parallel with the horizontal axis, and wherein the suction lead lines connect to a supply line that contains fracturing fluid from a blender, and the discharge line contains fracturing fluid pressurized by the pump.
