Pipeline Goose Neck
Wednesday, February 17, 2016
A gooseneck (or goose neck) is a 180° pipe fitting at the top of a vertical pipe that prevents entry of water. Common implementations of goosenecks are ventilator piping or ducting for bathroom and kitchen exhaust fans, ship holds, landfill methane vent pipes, or any other piping implementation exposed to the weather where water ingress would be undesired. It is so named because the word comes from the similarity of the pipe fitting to the bend in a goose's neck.
A goose neck can also be applied
on flexible pipe. Thus, the tie-in method is also different from the regular
pipe, such as:
- The connector module is lowered by guide wire.
- The module is landed onto the manifold hub.
- ROV makes up the connection using hot-stab on torque tool.
