UV technology for LPG composite cylinders and GFRP rods

News International-French

JEC Europe 2013 - With unique process and machinery engineering, COIA supports optimization goals by implementing UV technology into the manufacturing process of composite products e.g. liquefied petroleum gas (LPG) cylinders (Type IV) and glass-fibre reinforced plastic (GFRP) rods or profiles, thus replacing conventional thermo-curing.

Due to their low weight, explosion- and rust-proof properties, composite cylinders are on their way to conquer the worldwide market and to replace the usual steel cylinders.

The current production capacity for conventional thermo systems is approximately 2 million units/year. However, the world’s yearly demand for LPG tanks is around 120 million units, with an annual growth of 3.7%.

The challenge is therefore to maximize production capacity and simultaneously save raw materials and energy, reduce waste and eliminate hazardous volatile organic compounds (VOCs).

COIA offers innovative patent-pending filament winding technology, UV systems and  UV resins for the cost-effective and eco-friendly production of LPG composite cylinders.

The advantages of COIA’s UV technology for composite applications have been evidenced for more than 25 years in the processing of GFRP rods for the cable industry, with the company’s high-speed UV pultrusion machines, UV resins with low environmental impact and the related resin impregnation and curing systems.

COIA has just closed a deal with AL AMAN Gas Cylinders Manufacturing LLC in the UAE for a turnkey project to produce a total of 1 million cylinders/year.
