2205 Duplex Stainless Steel
- Toll Free number:1800-120-6232
Product Overview
In recent years metallurgists have developed superior grades of stainless steel known as Duplex (2205), having increased levels of chromium, nickel, molybdenum and nitrogen compared to popular grade 316. The result is a stainless steel that provides very good resistance to pitting and crevice corrosion in a seawater environment, making 2205 stainless steel a better option compared to 316 and 316L in such aggresive water environment.
Features
Six Layer Technology
The high-grade Class-O Nitrile Insulation and FGClad Fire resistance insulation which we procure from Italy, and minimum 50 mm and maximum 100 mm high-grade CFC/HCFC free polyurethane PU rigid foam insulation.
Inner Tank
The Tropinox tanks feature an ultra smooth non-corrugated Interior surface which effectively prevent lime scale deposits, all welded construction which ensures consistent efficiency over time.
High Corrosion Resistance
Duplex stainless steels good strength and excellent resistance to stress corrosion cracking in both general aqueous corrosion and chloride stress corrosion.
Thickness
Tropinox tanks are pressurized the thickness of stainless steel is 1.5 mm which are on average around 80% thicker than other manufacturers, of the same general capacities and dimensions.
Universally Suitable
When the customer suffering from Harsh water corrosivity, such us pH, sulphates, Chloride, hardness, conductivity, (TDS) total dissolved solids, iron and the ionic strength of the water, then Duplex Stainless steel is the best option.
Chromium Oxide Layer
The 22% of chromium content 2205 grade combines with oxygen in the air and water forms of passive layer of protection which prevents corroding when exposed to the dissolved oxygen and other aggressive elements found in all potable waters.
2205 Duplex Stainless Steel
Inner tank made of toughest and best grade of duplex stainless steel providing long lasting solutions even in harsh and aggressive water environment.
Water Level Controller
Automatic water level controller so that the water does not exceed the capacity of the tank.
Customised Stainless Steel Fittings
Tropinox Tanks can be ordered with multiple fittings, main sizes are available in 1”, 1.5”, 2”, however larger sizes and custom configurations are available upon request. This makes possible an optimum scope for Manifold connections.
Big Manhole
The cap hole is big enough to ease the process of inspection, maintenance and upkeep.
Quality Control & Testing
Throughout the manufacturing process all the tanks and vessels are subject to stringent quality checks. An overall test forms part of the FAT (Factory Acceptance Tests) procedures and the relevant documentation forms part of the FAT protocols.
Pressure Equipment Directive
The design and manufacturer of pressurized tank meet the requirements of european pressure equipments directives.
Weld Quality
These tanks are Pulse Tig welded with the most advance automated welding techniques to allow for more precise welding, providing a concentrated heat source.
