What is the standard operating pressure for foam branch pipes and inductors?

The equipment is designed to operate optimally at a pressure of 0.7 MPa (7 bar).

What are the standard capacities covered by this code?

The code typically covers FB-5X (225 liters/minute) and FB-10X (450 liters/minute) capacities.

What is the hydrostatic test requirement?

The components must withstand a hydrostatic pressure of 2.1 MPa for a duration of 2.5 minutes without showing any signs of leakage or permanent deformation.

Practical Notes

Ensure the foam inductor's flow capacity precisely matches the foam branch pipe to maintain the correct foam expansion ratio.

Regularly inspect and flush the inductor's pick-up tube with clean water after use to prevent blockages from dried foam concentrate.

Check material compatibility with the specific type of foam concentrate (e.g., AFFF, AR-AFFF) to prevent internal corrosion.
