Selecting the Correct Size Acetylene Manifold

To select the proper acetylene manifold for your operation, consider these points:

1. Calculate the flow (scfh) at each outlet in the piping system. Add the cubic feet per hour flow rate of each. The total will give you the volume of fuel gas needed per hour.
2. The manifold should have enough cylinders to provide for at least one day’s fuel gas requirements.
3. Acetylene withdrawals for continuous operation are 1/10th of the cylinder content per hour.
