Gooseneck vents are often found on atmospheric tanks.
A gooseneck refers to an industrial tank's vent pipe that is vertical, then makes a 180-degree bend downward toward the tank. It is used for atmospheric tanks that need to breathe through the vent. The gooseneck feature in the pipe prevents rain from entering the tank. Galvanized steel is a steel pipe that has been treated with zinc to protect it from corrosion. Typical gooseneck installations require two pieces of pipe; one straight piece that connects to the top of the tank and one curved (180-degree) piece that constitutes the gooseneck.
Instructions
1. Position the piece of galvanized steel spool on an available tank nozzle. Ensure the nozzle size matches the size of the spool piece. Insert the bolts, attach the nuts and secure it with the wrench. The tank nozzle is typically found on the top of the tank.
2. Position the elbow on top of the spool piece flange. Insert the bolts, attach the nuts and secure it with the wrench. This will create the curving gooseneck portion of the vent.
3. Attach the wire screen to the open end of the gooseneck vent to prevent birds from nesting inside the pipe. The brackets on the open end of the 180-degree piece of pipe typically have small bolts and a threaded, female end. Secure the screen in place with the bolts and tighten with the wrench.
