Piping systems and methods with an auger assembly

A frac iron system for oilfield operations, the frac iron system comprising:

• a plurality of pipe systems, each pipe system comprising:
• a pipe having an inlet and an outlet, the pipe defining a cavity therebetween configured to receive a flow of fluid containing a proppant;
• a fluid outlet fluidly coupled to the cavity between the inlet and the outlet;
• an auger assembly installed within the cavity and comprising:
• a helical blade extending at least partially between the inlet and the outlet, the helical blade configured to direct a portion of the proppant through the fluid outlet;
• a support coupled to the auger assembly, the support engaging the pipe to align a longitudinal axis of the helical blade with a center of the cavity;
• and
• a low-pressure connector fluidly coupling the outlet of the pipe of a first pipe system of the plurality of pipe systems to an inlet of the pipe of a second pipe system of the plurality of pipe systems.

A method of manufacturing a pipe system for oilfield operations, the method comprising:

• providing a pipe having an inlet and an outlet, the pipe defining a cavity between the inlet and the outlet configured to receive a flow of fluid containing a proppant and comprising a fluid outlet fluidly coupled to the cavity;
• providing a helical blade within the cavity such that the helical blade extends at least partially between the inlet and the outlet of the pipe;
• and
• coupling a first end of the helical blade to the pipe via a first end support and a second end of the helical blade to the pipe via a second end support, the first and second end supports engaging the pipe to maintain a proper position of the helical blade within the cavity.
