Pressure loss coefficients for close-coupled pipe ells.

Author(s) : RAHMEYER W. J.

Summary

Net pressure loss coefficients were studied for closely spaced or close-coupled pipe ells. The test fittings were all short radius (R/D: 5.08 cm) threaded malleable iron and 10.16 cm forged steel weld pipe ells. The ells were tested in the four close-coupled pipe configurations of a U shape of two ells in plane, a Z shape of two ells in plane, a torsional configuration of two ells out of plane, and a swing configuration of three ells out of plane. Data are presented. Findings concerning influence of fittings spacing, length/diameter ratios, or pressure losses for close-coupled pipe ells compared to the sum of pressure losses of the same pipes and fittings but uncoupled, are developed.
