VpCI technology to tackle corrosion

General Air, Cortec partner to strengthen fire sprinkler systems
The Vapor Pipe Shield is said to be a more dependable alternative to nitrogen blanketing or dried air for the protection of fire sprinklers against corrosion.

General Air Products has partnered with Cortec Corporation to develop a vapor phase corrosion inhibitor delivery system to tackle corrosion in fire sprinkler systems.  Robust firefighting systems are crucial to flexible packaging plants that are prone to fires. A major fire in a plant of Jindal Poly Films at Mundhegaon near Nashik claimed three lives on 1 January 2023.

General Air Products calls this new vapor pipe shield a ‘game-changing innovation in corrosion prevention technology for dry pre-action fire sprinkler systems.’ Cortec says facility engineers and consulting engineers can apply the benefits of the technology to critical fire suppression systems.

The Vapor Pipe Shield is said to be a more dependable alternative to nitrogen blanketing or dried air for the protection of fire sprinklers against corrosion. It relies on Cortec VpCI technology—vapor phase corrosion inhibitors that create a protective molecular shield on the inside of the sprinkler piping system. No special equipment is required; the cartridge is compatible with standard sprinkler setups and is easy to install between the air compressor and the piping.

Compressed air initially helps the vapor phase corrosion inhibitors diffuse throughout all branches of the piping system to form an active layer of protection on metal surfaces. Since these vapor phase corrosion inhibitors continue to protect as long as the system remains closed, corrosion mitigation does not depend on a constant source of electricity. That means a failed air compressor, nitrogen generator, or power source does not equal failed protection or require complete reapplication. Vapor phase corrosion inhibitors also protect in the presence of residual moisture and oxygen.

Packaging South Asia — resilient, growing and impactful — daily, monthly — always responsive

The multi-channel B2B in print and digital 17-year-old platform matches the industry’s growth trajectory. The Indian, South Asian, Southeast Asian, and Middle East packaging industries are looking beyond the resilience of the past three years. They are resuming capacity expansion and diversification, with high technology and automation in new plants and projects.

As we present our 2024 publishing plan, India’s real GDP growth for the financial year ending 31 March 2024 will exceed 6%. The packaging industry growth will match the GDP growth in volume terms and surpass it by at least 3% in terms of nominal growth allowing for price inflation in energy, raw materials, consumables, and capital equipment.

The capacity for flexible film manufacturing in India increased by 45% over the past four years. With orders in place, we expect another 20% capacity addition in 2024 and 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels are grown similarly. As the consumption story returns over the next six months, we expect demand to return and exceed the growth trajectory of previous years. The numbers are positive for most of the economies in the region – and as shown by our analytics, our platform increasingly reaches and influences these.

For responsible and sustainable packaging, with its attendant regulations and compliances, there is significant headroom to grow in India and the region. Our coverage includes the entire packaging supply chain – from concept to shelf and to waste collection, sorting, and recycling.

We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers. This is a large and complex canvas – the only thing that can work is your agile thinking and innovation together with our continuous learning and persistence.

The coming year looks to be an up year in this region, and this is the right time to plan your participation and marketing communication – in our rich and highly targeted business platform with human resources on the ground. Share your thoughts and plans to inspire and mobilize our editorial and advertising teams!
