The finished composite cylinder includes the following:

• The gas-tight liner made from PET (polyethylene terephthalate), which is fully wrapped by epoxy resin impregnated fiberglass to ensure strength. One of the features of such combination is that the wall is transparent, allowing the users to see how much gas remains within the cylinder. To install a typical valve the upper boss is provided that is reliably attached to the liner.
• The outer case made from HDPE (High Density Polyethylene), which provides extra protection and easy handling during transportation, it can be different in color according to customer's demand.

Cylinders are designed by using special CAD/CAM systems, and they are technologically optimized at the very stage of designing. Before being put into large-scale production, new types of cylinders are repeatedly and comprehensively tested in the research and development laboratory of KP, and then they are certified in accordance with international regulations and standards.

The main structural difference of KP cylinder from other cylinders is the thin-walled liner. Such cylinder structure allowed to ensure the following:

• high wall transparency
• minimum weight and production cost
• 150 times higher gas barrier rate rather than traditional PE (polyethylene) liner that is also porous and absorb gas pollutions
• corrosion free and free of stored gas contamination rather than metal cylinders polluting gas by corrosive products
• easy and safe boss-to-liner connection
• perfect strength of fiber glass

COMPOSAFER SMART cylinders employ the most recent RFID technologies (non-contact Radio Frequency Identification). Unlike steel cylinders, composite materials are radio transparent that ensures the use of read/write tags that need no fixed orientation of a signal receiver or transmitter, make communication data system and range much more informative, powerful and effective.

The integrated chip bears copyright information that cannot be disclosed, and it is used by counterfeited. It keeps KP process/quality control information or electronic passport during all cylinder life. During cylinder operation this chip, which is also called high frequency transponder, securely stores and accumulates information needed for a cylinder owning company.

Gas companies that use COMPOSAFER SMART cylinders achieve a high level of business competitiveness and efficiency because they:

• have full, true, hot information about quantity, location, and condition of the cylinders to improve logistics and cylinder management system
• increase filling output and accuracy, make this process fully automatic and integrated into Company Accounting System to reduce gas processing loss and personnel costs
• offer new value-added services to customers, such us consumption and invoices history and enlarge the possibilities of e-commerce.
