Quality Assurance:


As Dynaglass® prides herself on quality in evidence, it is only logical that a series of tests are conducted on products and samplings. Dynaglass VAPOLOCTM meets British Standard BS EN13121-3: 2008.

A sheer test on a panel of the Dynaglass VAPOLOCTM was conducted on 24 June 2003 by Hercules Test Centre, Singapore. Results show design break load of 17,000 kg (37,570 lbs) was well exceeded and parent material failed at 27,800 kg(61,438 lbs) while joint remained intact.

A Fire Test was also conducted on the IFR. Results show that there were only surface damage to the roof but the roof was discovered to be still intact and in good condition.

Apart from product tests, all Dynaglass VAPOLOCTM are inspected and monitored during installation. This includes close monitoring of styrene exposure to workers. Average reading achieved is 1.54ppm/8 hour shift within tank (OSHA requirement- Limit of 20ppm). Prior to comissioning, integrity of joints are leak tested to ensure zero pin-holes.

Joint Strength:Dynaglass developed the prefabricated Dynaglass VAPOLOCTM (Patent protected). The system mandates that all components to be manufactured at the plant in under controlled environmental conditions to overcome all the above challenges. This ensures that the product is delivered with consistent quality. The prefabricated parts accounts for about 90% of the IFR while connecting them in the tank only makes up for 10%

Unlike metal welding which can cause the parent material to become weak due to differences in material and temperature, Our patented joint system will infact create a stronger finished material.

Lab tests results showed favourable results where parent material broke over 10,000kg more than the design break load of 17,00kg. Dynaglass VAPOLOCTM Joint remained intact at 27,800kg.

“No maintenance is required as it does not rust, corrode or rot”

“Return on investment of 10 to 15 years and beyond is meaningful”

“It is strong, rigid and stable even at high filling rate”

“We can even use as a safe working platform during maintenance”

“Erection of internal scaffolding is not required for maintenance of fixed roof”

“We do not need to invest and maintain the cost of running a tank blanketing or vapour recovery system”

“It is a full contact roof so no dangerous vapours are trapped below the decks”

“Unlike stainless steel and carbon steel roofs, it is lightweight, we could increase storage space without the need to increase existing storage capacities”

“It is excellent for storing products like bio-fuels, ethanols, etc.”

Comparative Table:

Q1. What is the maximum allowable load (kg/m2) when IFR is floating on the product? A1. Maximum allowable load, w = 33kg/m2 (Equally distributed load).

That means when 33 kg is loaded on the area (1m x 1m), the top surface will be flushed with the level of product in the tank (see fig (1).

(Note: 33kg/m2 = 6.76 lb/ft2 or 0.04694 lb / inch2 )

Q&A:


Q2. What is the maximum distribute allowable load on the IFR when it is floating on the product for 36m dia. & 24m dia. tank.

A2. For 36m dia. IFR: 32847 kg For 24m dia. IFR: 14435 kg

Q3. What is the maximum allowable compression load (N/m2) when IFR is supported by the flat base?

A3. eg. When IFR is rested on the tank floor which is improbable taking into consideration mixers, mounts

& etc, the maximum allowable compression load is 130000N/m2 (The Safety Factor for the core was taken as 10).

Q4. What is the maximum allowable load when it is resting on support legs / chains? A4. The “Vap-O-Loc“ IFR is designed to take its own weight (inclusive of the seal & appurtenance) plus

live load according to API 650 H. It is also designed to support at least two men (500 pounds over 1 square foot) walking anywhere on the roof.

For roofs less than 30 feet in diameter, these criteria may be waived subject to agreement between

the purchaser and Dynaglass regarding the need for access and minimum concentrated live loads. Q5. What is the consequence if a concentrated load is only on one end of the IFR when it is floating

on the product and what is the maximum allowable concentrated load it can take for 36m dia. and 24m dia. tank?

A5. If the load is only on one end of the IFR when it is floating on the product, IFR will be tilted and one

end of the top surface of IFR will be flushed with the level of the product in the tank (see fig (2). For 36 m dia. tank, maximum allowable load = 3000 kg

For 24 m dia. tank, maximum allowable load = 1000 kg

Q6. What is the standard height of rim flange? A6. 319mm

(319mm = 1.0466 ft or 12.56 inches) Q7. Can radar level gauge be used on Vap-O-Loc IFR? A7. Yes, for more information please check with Dynaglass.

Q8. What is the weight per panel? A8. There are three types of panels such as standard panel, transitional panel and rim panel. The weight

of standard panel is 67kg (approx). (67kg = 147.71lb)

Q9. What is the size of standard panel? A9. 2200mm x 2200mm

(2200mm x 2200mm = 7.218ft x 7.218ft or 86.614 inches x 86.614 inches) Q10. What is the thickness of panel? A10. 66mm

(66mm = 0.2165 ft or 2.6 inches) Q11. What is installation time for a 24m, 36m or a 48m diameter tanks? A11. For 24m dia. tank = 2 week (150 man-day - approx.) (24m = 78.74 ft or 944.88 inches) For 36m dia. tank = 4 week (260 man-day - approx.) (36m = 118.11 ft or 1417.32 inches) For 48m dia. tank = 4 week (380 man-day - approx.) (48m = 157.48 ft or 1889.76 inches) Q12. How many 40ft Containers will accommodate a 36m diameter tank and equipment? A12. 4 nos. of 40 footer containers. Q13. What are the items and quantities that will be supplied for 36m dia. IFR?

A13 The following items and quantities will be supplied for 36m dia. IFR.

Standard Panels, transitional panels and rim panels = 253 nos.

Support legs = 42 nos. Deck drains = 5 nos. Gauge pole seal = 1 no. Manhole cum vacuum breaker = 2 nos. Rim pressure relief valves = 4 nos. Raw Materials for site lamination = 1 lot

Q14. What is the space between the rim of IFR and the tank wall? A14. 200mm

(200mm = 0.656 ft or 7.874 inches) This gap is designed to fit many types of tank seal.

Q15. What is the height of support legs? A15. 1400mm (standard height)

(1400mm = 4.59 ft or 55.12 inches) Height of the support leg is agreement between buyer and Dynaglass.

Q16. Can legs be designed to be adjustable? A16. Yes, can be adjustable as per request.
