1. A pig routing insert configured for installation in a structure, the pig routing insert comprising:
a cylindrical insert body configured to be positioned at an intersection of at least two perforated fluid flow holes defined within a body of the structure;
a first substantially unrestricted flow opening defined in the cylindrical insert body which is configured to allow substantially unrestricted fluid flow and a cleaning pig to pass through the substantially unrestricted flow opening;
a second substantially unrestricted flow opening defined in the cylindrical insert body which is configured to allow substantially unrestricted fluid flow and the cleaning pig to pass through the substantially unrestricted flow opening; and
a plurality of partially restricted flow openings defined in the cylindrical insert body comprising at least one pig blocking structure positioned within each partially restricted flow opening, wherein the plurality of partially restricted flow openings comprises a first partially restricted flow opening formed in an end surface of the cylindrical insert body and a second partially restricted flow opening formed in a cylindrical side surface of the cylindrical insert body, wherein each of the plurality of partially restricted flow openings is configured to allow substantially unrestricted fluid flow through the plurality of partially restricted flow openings whilst blocking passage of the cleaning pig through the plurality of partially restricted flow openings.
