Fixed roof tanks

JPM is designing and building fixed roof tanks (with and without steel cup) for all applications and storage products. Here, the different requirements and design parameters are taken into account such as:

  • Design codes: EN, EEMUA, DIN, API, ASTM, ASME, BS, Codres, etc.
  • Applications: chemicals, petroleum, food, H2O, liquefied gases
  • Material: carbon steel, stainless steels, etc.
  • Temperature range: from -200 °C to +300 °C
  • Design pressure: of from atmospheric to about 1.000 mbar
  • Specific gravity: of less than 1000 kg/m³ to 2,000 kg/m³ and heavier
  • Sizes: of small and factory-made tanks with 100 m³ content to large storage tanks with 70,000 m³ content and more
  • Tank bottom: Flat bottom overlapped or butt welded, full overlay or with grillage, performed with and without gradient or as a cone bottom
  • Tank roof: self-supporting domed- or cone-roof or ALU -Dome
  • Floating roof: Full contact pontoon floating roof equipped with the JPM floating roof seal SWING II

The necessary safety equipment for trouble-free operation of different operating applications are selected and dimensioned by our engineers according to the relevant standards:

  • Irrigation as a cooling system for protection against fires of neighbouring structures
  • Foaming system as a fire extinguishing system for fighting fires
  • Different internal and external heating systems to control the temperature of the stored products
  • Over-and under -pressure devices to provide protection against pressure damage
  • Overfill prevention (High Level, Low Level)
  • External inspection facilities e.g. stairs, ladders, platforms, etc. to ensure safe accessibility of safety- and operating-equipment as well as measurement devices.
  • Facilities for inspection of the tank interior such as manholes and cleaning openings
  • Roof and tank shell nozzles for different applications and in various designs e.g. double-walled
  • Equipment for leakage monitoring of tank bottom and tank shell.
  • Tank anchorages according to the designed pressure range and the applicable seismic loads and in accordance with the available foundations
  • Additional equipment required for the safe operation e.g. infeed equipment, dip tubes, floating suction units, skimmers, etc.
