Abstract

An irrigation pipe and method of fabrication that utilizes a pipe that is made of a durable material, e.g., stainless steel or aluminum. During fabrication, the pipe is equipped with a plurality of components, i.e., a flange assembly, a truss mount, and an outlet, without drilling, welding, or the like. In this manner, a method of fabrication is provided that enables a plurality of components to be assembled to the pipe without compromising the integrity of the pipe material or treated surface so that galvanizing or painting is not required after the plurality of components have been fitted to the pipe.

First claim

What is claimed is:

1. An irrigation pipe assembly having a liquid conduit for the delivery of liquid, the assembly comprising:
a plurality of pipe sections operable to provide a portion of the liquid conduit, each pipe section having flanges at opposing ends thereof, each flange having a plurality of apertures; and
a plurality of flange plates positioned at the opposing ends of the pipe sections such that each flange plate is adjacent one of the flanges of the pipe sections, each flange plate having an abutment surface including a plurality of apertures and a circumferential groove therein, the circumferential groove being radially exterior to the apertures of the flange plate, the abutment surface operable to abut the adjacent flange and receive a portion of the adjacent flange therein, the apertures of the adjacent flange and the apertures of the flange plate being configured to be aligned with each other for receiving fasteners therethrough so as to secure the pipe sections together via the apertures of the flanges of the pipe sections.

2. The irrigation pipe assembly according to claim 1 , wherein the flange plates are operable to be secured together such that the flanges of the pipe sections are substantially enclosed by the flange plates.

3. The irrigation pipe assembly according to claim 2 , wherein the flange plates are operable to space ends of the fasteners from the flanges of the pipe sections.

4. The irrigation pipe assembly according to claim 1 , wherein the flange plates each have eight apertures and the flanges each have eight apertures.

5. The irrigation pipe assembly according to claim 1 , wherein the apertures of the flange plates are equally spaced from each other and the apertures of the flanges are equally spaced from each other.

6. The irrigation pipe assembly according to claim 1 , wherein the apertures of the flanges are formed by a punching process.

7. The irrigation pipe assembly according to claim 1 , further comprising a plurality of gaskets positioned between the pipe sections for forming a water-tight fit.

8. The irrigation pipe assembly according to claim 7 , wherein the gaskets are flat ribbed gaskets.

9. The irrigation pipe assembly according to claim 1 , wherein each flange includes a flange face oriented approximately ninety degrees to a length of the pipe section.

10. The irrigation pipe assembly according to claim 9 , wherein each flange further includes a flange end curving approximately parallel to the length of the pipe section and being configured to be inserted into the circumferential groove of the respective flange plate.

11. The irrigation pipe assembly according to claim 1 , wherein the pipe sections are formed of carbon steel and are galvanized with a protective coating.

12. The irrigation pipe assembly according to claim 1 , wherein the pipe sections are formed of carbon steel, stainless steel, or aluminum that is covered in a protective coating in the form of a galvanized layer or painted layer.
