In this case study, we present a scenario where an Ethylene tank in a Chemical Plant suffered significant damage to its roof and staircase due to severe corrosion in the skirt area. Rainwater accumulation and harsh environmental conditions were the primary causes of the corrosion. The client sought a quick and efficient solution to address […]
Our client, a large phosphoric acid plant was suffering huge chemical and environmental corrosion due to fumes of phosphoric and sulphuric acid and coastal environment. Standard Epoxy paints were peeling off within 6 to 8 months and the outer walls of the tank were getting heavily corroded. After cleaning the storage tank wall, surface preparation […]
A leading power plant, faced a leakage issue due to gasket failure of Boiler Feed Water Pump. Clients could not afford to shut-down due to heavy production loss, thus asked NESL for an online leak-sealing solution. Our engineers took precise measurements of the Flange Joint Line and fabricated and installed a clamp. NESL Leak-Sealing compound […]
One of our clients faced Super heated Steam Leakage from Hot Re-Heater line crack. Pressure 110 bar and Temperature 600°C. Our engineers analyzed the root cause of the leakage, took a precise measurement and engineered a box-clamp. The clamp was installed over the leak and special-purpose Leak-Sealing compound NESL-2H was injected. The leakage was arrested […]
The Blast-Furnace pump efficiency was reduced due to pitting and corrosion. A Glass flake coating was done each year and did not last or help. The asset owner asked NESL for a Belzona solution. Our service engineer deployed Belzona 1111 to fill the pitted surface and used the energy-enhancing PTFE-based Belzona 1341 supermetal glide to […]
Blast-Furnace pipe thickness decreased as a result of corrosion, client adopted a conventional repair to the damage and welded the corroded area during shut-down. The repair was not successful so the owner asked NESL to undertake The Belzona Solution. Our service engineer selected Belzona 1161, a fast-curing, surface, oil and moisutre tolerant paste-grade composite along […]
A recent case of hot steam leakage of 20 TPDS HEATER FLANGE LEAKAGE near control room was addressed by our service engineer Mr. Soumya Deep Chatterjee. The leakage was at a temperature of 350°C and Pressure 15 Bar. Online Leak Sealing by Brass Wire Peening Method was adopted. Leak Sealing Compound NESL-2B was injected through […]
NESL’s design and fabrication team has always worked hand in hand to provide the best possible leak-sealing solution in the shortest outage window.
