A 700 kg/cm2 fracturing manifold is designed for very high-pressure fracturing service. It collects discharge from fracturing pump units and distributes the flow to the wellhead through controlled high-pressure outlets.
The manifold typically includes plug valves, check valves, pup joints, tees, crosses, elbows, hammer unions, pressure gauges, and relief or bleed-off connections. All pressure-containing parts must be rated for the specified working pressure and compatible with the fracturing fluid.
Design attention should be given to flow erosion, pressure pulsation, support points, connection alignment, and line restraint. Abrasive proppant and high velocity can shorten the life of elbows, tees, and valve seats.
Before field use, the assembly should be pressure tested, function tested, and inspected for damage. During operation, pressure changes should be controlled and personnel should remain outside the high-pressure line hazard area.
