sir,
there is not a general answer to your questions since it depends on fouling level; for design purposes my rule is that horizontal piping equivalent lenght should not belonger than 100 ft and turns should be minimized as possible; when required for stress or piping arrangement constrainsts, then long 120 degree ells should be used and cleaning connection located to the ell closest to the 100 ft; the connection size should be min 6 inches and max 10″, and located in horizontal position and tangential to bottom of the pipe.
