Non Contact Pontoon IFR

Normally our Skin and Pontoon type Internal Floating Roofs fall into three different types; Aluminium, Stainless Steel and Hybrid design and will fall into one of three different regularly standard used live load classes:

MSP-AL
• MSP-AL500 Pontoon Internal Floating Roofs- Aluminum 500
• MSP-AL750 Pontoon Internal Floating Roofs- Aluminum 750
• MSP-AL1000 Pontoon Internal Floating Roofs- Aluminum 1000

MSP-S

• MSP-S500 Pontoon Internal Floating Roofs- Stainless Steel 500
• MSP-S750 Pontoon Internal Floating Roofs- Stainless Steel 750
• MSP-S1000 Pontoon Internal Floating Roofs- Stainless Steel 1000

MSP-H

• MSP-H500 Pontoon Internal Floating Roofs- Hybrid 500
• MSP-H750 Pontoon Internal Floating Roofs- Hybrid 750
• MSP-H1000 Pontoon Internal Floating Roofs- Hybrid 1000

MGL Project Internal Floating Roofs are custom designed to each individual tank within the requirements of API 650. All our Internal Floating Roofs are designed by our design and engineering team utilizing the latest technology to assure that you have the most efficient Internal Floating Roofs in your storage Tanks. Our Internal Floating Roofs are often designed to an end users’ specific criteria that exceeds the standard design and requirements.

In today’s market the standard internal floating roofs, fitted with the correct seals, will be compatible with most of the petroleum industries products. For those controversial products such as Methanol and Ethanol, we provide the Stainless-Steel pontoon Internal Floating Roofs and the Hybrid (Stainless Steel Wetted Parts) pontoon Internal Floating Roofs. These Hybrid Internal Floating Roofs are cost effective in the smaller diameter tanks due to the installation not requiring any tank modification for entry of material.

Advantages of the Aluminium, Hybrid and Stainless-Steel Skin & Pontoon Internal Floating Roofs when compared to the controversial Steel Floating Roofs:
• Allows more tank capacity, which makes the floating roofs cost effective
• All components can be introduced through a 20″ manway, this prevents high out of service implementation costs
• Positive flotation, will ensure operations during in service periods
• Faster turnaround from delivery to installation, results in downtime savings
• Optimum ability to handle most tank shell irregularities, this will prevent the system from jamming during operations

Skin & Pontoon Internal Floating Roof Structure
The pontoon Internal Floating Roof is a structure consisting of a series of interconnected hollow tubular pontoons surfaced with metal sheets.
The surface tubular pontoons are laid out on a supporting grid work of extrusions with the edges overlapped and clamped in vapor tight metal-to-metal joints connected by straps and fasteners.

Skin & Pontoon Internal Floating Roof Support Options
When landed, the Internal Floating Roofs can be supported by fixed or adjustable legs or can be supported by a chain or cable suspension system. Whichever supporting systems might be used the supports are situated in between the pontoon connector sections and on a few locations on the perimeter.

Fitted floating roof peripheral fitted rim seals
The most commonly used Floating Roof Rim Seals either used as a single or combined configuration are:
• MRS-1/350 Primary Mechanical Shoe Seal
• MRS-7/350 Primary Foam Filled Seal
• MRS-60 Primary XPE Wiper Seal
• MRS-70 Secondary XPE Wiper Seal
