Are COMPOSAFER® cylinders safe?Safety is of our prime concern when it comes to LPG cylinders. Hence Kompozit-Praha takes first and foremost care to supply customers with safe and explosion proof composite cylinders. Stringent testing in R&D lab and strict compliance with international regulations and standards make COMPOSAFER® cylinders the best option for different applications, both domestic and industrial.
COMPOSAFER® cylinders are manufactured under strict guidelines of EN12245 and EN14427, EC/36/1999/TPED and ADR/RID. The cylinders are marked with π sign in compliance with TPED Directives. COMPOSAFER® cylinders are certified by German company TÜV and approved by U.S. Department of Transportation (DOT).
Can a COMPOSAFER® cylinder burst out?No.
COMPOSAFER® cylinders are explosion proof in open fire due to a unique design when they are engulfed in open fire.
Is there any weight difference between a COMPOSAFER® and a steel cylinder?COMPOSAFER® cylinders are twice lighter than steel ones and can hold an equivalent amount of LPG.
What does it mean that COMPOSAFER® cylinders are non-corrosive?COMPOSAFER® cylinders will not rust as it happens with steel cylinders since COMPOSAFER® cylinders are manufactured from non-corrosive material - plastic and fiberglass.
Can we use the same valve as we are using for steel cylinders?Yes.
COMPOSAFER® cylinders can be equipped with any valve and any thread according to customer demand. It means that COMPOSAFER® cylinders do not require any extra expenses arising from using special valve.
Can we choose any colour?Yes.
The outer casing of COMPOSAFER® cylinders can be delivered in colour variations. Specific colours can be chosen from RAL colour card.
Moreover the company name and/or logo can be put on the outer casing of COMPOSAFER® cylinders.
How do I fill a COMPOSAFER® cylinder?Before a cylinder is filled Kompozit-Praha advises to visually inspect the cylinder. If any observed damage meets or is more severe than Kompozit-Praha's recommendation for pre-fill inspection, the cylinder must be removed from service.
When a pre-fill inspection of the COMPOSAFER® cylinder has been completed and no damage noted, the cylinder can be filled by following the filling instructions.
What must be done before a COMPOSAFER® cylinder is filled for the first time?If the COMPOSAFER® cylinder is going to be filled for the first time, it must be de-pressurized first. COMPOSAFER® cylinders are supplied with pressurized air so you can check cylinder impermeability.
When COMPOSAFER® cylinders must be retested?The interval of periodic inspection of COMPOSAFER® cylinders is in compliance with Directive ADR/RID set for 10 years.
What is the practice to be adopted for refilling composite cylinders?Composite cylinders can be filled and refilled exactly like the steel cylinders. The ideal and the best practice is to fill the cylinders based on the gross weight. E.g. if the tare (empty) weight of a 12 kg. LPG Composite cylinder is 5.5 kg. then with 10 kg. of gas the gross weight will be 15.5 kg.
At the time of every refill, the filling in the composite cylinder may be done so as not to exceed the gross weight of 15.5 kg. It is not desirable to tare the weighing scale at every fill due to small variation in LPG gas residue varying on ambient temperature.
