STEEL PIPE REDUCER ASME SA335 P91 508*17 ALLOY BLAC
The action of eccentric diameter variation is that the diameter of the pipe mouth at both ends of the eccentric head is different ,so it is used to connectric the pipe or flange of diffrernt diameter to change the diameter of the pipe or flange .Eccentrically small head at both ends of the mouth ,the center of the center on the same axis ,the position of the pipe remains the same ,generally used for gas or vertical liquid pipeline diameter change .Eccentrically small ends of the pipe mouth circumferential cutting ,generally used in horizontal cutting ,generally used in horizontal liquid pipes .When the cut point of the eccentricity head is upward ,it is called top level installation ,which is generally used for pump inlet ,which is beneficial to the bottom level installation ,which is generally usde for the installation of control valve and the use of drainage .Eccentric head is changed ,so the concentric and different diameter pipe is used in the liquid pipeline with gas ang vertical fiow .Eccentric size head because one side is flat, conducive to exhaust or drainage,easy to start and repair ,so the horizontal installation of liquid pipe is generally used eccentric different diameter pipe.
