Product Overview
Horizontal Storage Design
Suitable for ground-level installation, subject to foundation design and site layout.
Configurable Double-Wall Structure
The interstitial space can be specified for insulation, leak containment or other defined functions.
Heating System Integration
Compatible heating arrangements and pipe connections are determined by the required storage temperature and plant utilities.
A Double-Wall Horizontal Bitumen Tank stores heated bitumen in an inner vessel enclosed by an outer shell. Its configuration can be tailored to project requirements for thermal insulation, secondary containment or external protection.
Double-Wall Configuration Options
Select the outer-shell arrangement according to thermal, environmental and site requirements.
Insulated Double-Wall
Insulation is installed between the inner vessel and outer shell to limit heat transfer. Thermal performance depends on insulation type, thickness and ambient conditions.
Secondary-Containment Design
The interstitial space is engineered to collect leakage from the inner vessel. Containment capacity, monitoring and applicable regulatory requirements must be confirmed.
Protective Outer Shell
An external shell provides physical protection. It should not be treated as certified secondary containment unless specifically designed and verified for that purpose.
Technical Specifications
Final specifications depend on storage capacity, bitumen grade, operating conditions and applicable project requirements.

Frequently Asked Questions
Q: What is the main advantage of a double-wall horizontal bitumen tank?
A: It combines an inner storage vessel with an outer shell that can be configured for insulation, secondary containment or physical protection. The actual function depends on the specified design.
Q: Does every double-wall tank include insulation and leak detection?
A: No. Insulation, interstitial-space design and leak-monitoring equipment must be specified separately. A double-wall structure alone does not establish that all containment or monitoring requirements are met.
Q: How is the heating capacity determined?
A: The calculation considers storage volume, bitumen grade, starting and target temperatures, ambient conditions, insulation performance and the required heat-up time.
Q: Can the tank be integrated into an existing asphalt plant?
A: Integration can be evaluated using the plant layout, storage demand, heating utilities, pump capacity, pipeline connections and available installation space.
Q: Which design standards apply to the tank?
A: The applicable standard depends on the tank's design conditions, construction type, intended use and destination-market requirements. The relevant code should be confirmed during engineering review.
