How to create flange connections on pipes?
Thread Content
If a flange connection is to be created on a DN100 pipe for use with a pressure gauge, how is it typically constructed? Just cut a hole in the pipe, then weld on a short section, a flange?
Create a new project using a tee! Renovating old projects: making holes in the pipes!
What I saw on site was exactly as you described.
Take a tube and draw a circle around the tube with a diameter of 100
Check the pressure level. Use a U-tube or not. The pressure gauge should be a four-piece assembly, right?
A hole can be made to directly weld the short pipe, and then a flange can be attached. But it depends on the diameter of the branch pipe; if it is the same as that of the main pipe, a tee must be installed.
Holes are allowed, but reinforcement calculations need to be performed. For example, when working with a DN25 flange, it is necessary to determine the pressure level, as well as the wall thickness of both the main pipe and the straight pipes. Reinforcement calculations must be carried out in accordance with the applicable standards; only then can construction proceed. For detailed calculations, please contact me directly. Communication
1. For pipes newly designed and installed with DN100, use an eccentric tee + short pipe + flange. 2. For existing DN100 pipes: make openings, add branch pedestals + short pipes + flanges.
Check the pipeline medium, pressure, and condition; mechanical tapping, branch stubs, short pipes, flange welding
