Claims9
A prefabricated header-connector assembly adapted for inclusion in a sewage aeration tank by the attachment of a low pressure air supply and diffusers to a plurality of interconnected header-connector assemblies in which said assembly maintains said attached diffusers in proper alignment in a common plane, said assembly comprises;
- a header formed of weldable material capable of having nipples drawn therefrom, a plurality of outwardly projecting nipples drawn from said header at spaced locations on said header,
- a plurality of connectors each secured to said header at different ones of said spaced locations, each of said connectors oriented in a transverse direction to the direction of said header, said connectors having coupling means for coupling to diffusers,
- each of said connectors having nipples drawn therefrom with the open end of said connector nipples welded to different ones of said header nipples.
An aeration system comprising header means arranged in an aeration tank on support means in generally horizontal relationship, with transverse horizontally disposed connectors secured to said header means at longitudinally spaced locations along said header means for supporting diffusers, the improvement characterized in that;
- said header means is a tube comprising weldable material capable of having nipples drawn therefrom, and including outwardly protruding nipples at said spaced locations composed of integral arcuate cross-section extentions of the header-tube wall material and terminating in a planar face,
- said connectors are tubes including outwardly projecting nipples composed of integral arcuate cross-section extensions of the connector-tube wall material terminating in a planar face,
- the planar faces of said header nipples and said connector nipples engaging each other, and
- said nipples being welded together in register to provide a smooth transition between the inner surfaces of the header nipples and the connector nipples.
