Flexible Bend Master Articulated
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 (75mm) diameter less than 120 ft or smaller than 4 ins (100 mm) diameter for with a diameter greater than 120ft.
ATECO TANK TECHNOLOGIES can provide this Roof Drain System completely prefabricatedwith an Istallation Manual for final assembly and Installation at site by the customer. Altema ATECO TANK TECHNOLOGIES and ENGINEERING can install the Roof Drain Systems using our own installation crew at a time convenient for the customer.
This Drain System comprises of rigid pipe, normally carbon steel and a number of flexible bend joints. the flexible bend joints incorporate flexible hose material fixed within a sainless steel or galvanised carier frame and are specifically designed for submerged service and the operational requirements of the drain system. it is normal practice to have 4 no flexible bends where the tank diameter is greater than the height and 3 no where the tank diameter is less than the height.

Design FeaturesThe ATECO Bendmaster flexible joint is designed with inner and outer stainless steel wire helixes to maintain hose rigidity when subjected to internal or external pressures. Multiple inner layers of polar and non-polar elastomeric materials in the flexible joint prevent product permeation through the hose, even from such products as MTBE. The outer layers of this woven fabric protect the inner hose materials. Its high design pressure also makes the Bendmaster suitable for use with fire fighting foam delivery systems. The flexible joint pivot-pin design uses stainless steel bushings and spacers to eliminate binding and assure flexibility. No lubrication is required. The reinforced side plates transfer the load around the flexible hose, eliminating stress on the hose end connections and minimizing the possibility of hose end failure. These side plates are available carbon steel (galvanized or prime coated) and stainless steel materials. Bendmaster flexible joints are attached to Schedule 40 carbon steel piping to provide a rigid, maintenance-free drain system. Piping diameters of 3" through 10" are readily available from stock.
