Abstract

576,568. Pipe bends. AKT.-GES. BROWN, BOVERI, & CIE. Jan. 20, 1944, No. 1139. Convention date, Jan. 20, 1943. [Class 99 (i)] [Also in Group XXXVII] A pipe-bend for pressuregas piping leading to a gasblast switch b has a circular inlet c and an annular outlet d and means to ensure that the velocity oi flow of gas is distributed evenly over the discharge end. This is effected either by providing a bulge a or tapered ribs extending from a horn arranged along the axis of the pipebend. The flow may be further steadied by concentric cylindrical guides e, located at the outlet or in the switch chamber itself.
