Flexible Bend Articulated Roof Drain System
For External Floating Roof Tanks
The Flexible Bend Articulated Rigid Pipe Roof Drain System is used to
remove rain water from the roof of an External Floating Roof Tank.
The Roof Drain System is designed to remove rain water so as not to put
unacceptable loadings on the roof. API 650 Appendix C states that the
drain system shall not be smaller than 3 ins (75 mm) diameter for roofs
with a diameter less than 120 ft or smaller than 4 ins (100 mm)
diameter for roofs with a diameter greater than 120 ft.
Land and Marine TankServ can provide this Roof Drain System completely
prefabricated with an Installation Manual for final assembly and
installation at site by the customer. Alternatively Land and Marine
TankServ can install the Roof Drain Systems using our own installation
crew at a time convenient for the customer.
