More into Key Features of our Mechanical seal system
Our Floating Roof Rim Seal Benefits:
Equipped with a rim seal system.
Rim seal system is attached to the roof perimeter and contacts the tank wall.
System slides against the tank wall during roof movement.
Floating deck includes fittings for operational functions.
Tailored for various types of above ground storage tanks (ASTs).
Designed to satisfy all protection needs
Prevention of Damages and Movements:
Prevents horizontal movements that may damage tank features.
Designed to positively center the floating roof.
Dampens horizontal roof movements to a minimum.
Secondary Rim Seal Features:
Exposed material designed to meet or exceed fire-retardant level requirements.
Secondary rim designed as low as possible for increased filling capacity.
Design Limits Evaporative Losses:
Evaporative losses limited to rim seal system, deck fittings, and exposed liquid on tank walls.
Standing storage loss and withdrawal loss are considered.
Critical Criteria for Effective Rim Seal:
Compliance with basic criteria for cost-effectiveness.
Parts designed to be product-resistant due to contact.
UV-resistant materials used for parts exposed to sunlight.
Wear-resistant materials for parts involved in sliding movements.
Adaptability to Working Range:
Analyses and evaluates the working range based on Maxwell design input.
Complies with API requirements (e.g., +/- 4″ or 102-mm) or other local laws and guidelines.
Adaptable to different working ranges (e.g., EEMUA 159, NEN-EN 14015).
