EZfit

Floating-roof fittings and emission-control details

The small openings that decide whether the large roof performs: wells, sleeves, leg seals, gauge-pole details, covers, vents and local penetrations engineered to reduce uncontrolled vapour paths.

Schematic of sealed floating roof fittings and penetrations
Design intent

A good roof can still emit through a poor fitting.

Deck fittings and penetrations are local discontinuities in the emission-control envelope. Their geometry, movement and sealing detail should be developed together with the roof rather than added as catalogue accessories at the end of the project.

EZfit is the project-specific family for these interfaces: guide and gauge-pole details, leg seals, well covers, sleeves, local skirts, vents and other emission-control fittings.

Engineering priorities

What the design has to get right.

01

Close local vapour paths

Fittings are detailed around actual movement and clearance rather than nominal opening size alone.

02

Keep movement possible

Sealing must not prevent the fitting, leg or pole from performing its operational function.

03

Coordinate materials

Fabrics, polymers, aluminium and stainless elements are selected for the stored product and service.

04

Inspect and replace

Wear elements remain accessible and replaceable without redesigning the roof.

Scope

Typical EZfit scope

  • Gauge / guide pole sleeves and local sealing
  • Support-leg seals and socks
  • Well and cut-well covers
  • Roof vent interfaces
  • Penetration skirts and vapour barriers
  • Custom fitting seals for existing roofs
Inputs

Design inputs

  • Roof type and deck construction
  • Fitting diameter, movement and operating position
  • Product compatibility
  • Required emission-control level
  • Existing obstructions and installation access
  • Inspection / replacement philosophy
Standards & project basis

Designed from the application, then checked against the code.

Fitting details are checked against the applicable floating-roof and emission-calculation basis for the project. Performance depends on installation and the complete roof configuration, not the fitting in isolation.

Application review

Start with the tank, the service and the result you need.

Emission Zero can review the application before turning it into a product configuration or project specification.
