Pulp and PaperIn pulp and paper applications, stainless steel is used extensively because of its good mechanical properties and its resistance to liquor used in the process. These benefits will become even more of a priority as pulp mills move into the realm of bio- refineries.Stainless steel’s properties prevent contamination of the end product and are resistant to process corrosion. Although the process is mostly standard at all mills, there can be small mill-to-mill differences that may affect levels of corrosion. Stainless steelis able to withstand these differences in a stable, uniform manner that makes it the most reliable choice for these applications.Some of the more common applications for stainless steel conduit in the pulp and paper industry include:• Batch and continuous digesters• Brown stock washers• Black liquor equipment and tanks and recovery circuits• Bleach plant• Lime kiln (for high temperature properties)• Air and water pollution control equipment• Waste paper recycling• Stock preparation equipment• Paper machines including suction rollsWater and Waste WaterIn recent years, the use of stainless steel in water and wastewater treatment plants (WWTP) has grown significantly, as type 304 and 316 gradesare increasingly utilized as standard materials of construction due to superior performance and cost- saving factors. A WWTP is a complex, sophisticated system with a high-level of standards for the entire plant, including technical installations. The materials needed to construct a WWTP must be able to withstand the wide range of corrosive conditions.For a clean, environmentally safe and cost-effective plant, there is no better material than stainless steel. Stainless steel will improve efficiency, reduce maintenance, and in many cases, provide the most cost-effective solution.Benefits to this industry include:• Corrosion resistance to a wide range of waters, chemicals, such as Hydrogen Sulphide (H2S)• A protective layer forms naturally on all stainless steels because of the inclusion of chromium. Even if damaged and oxygen is present, the invisible passive layer "self-heals" and protects the steel from corrosion, ensuring a long life• Stainless steel is not harmful to people during its production or use, recycling and ultimate disposal• Good strength and ductility• Ease of fabrication• Lightweight and easy to transport• Availability in a wide range of product forms • Durability• Fully recyclableTransportation / InfrastructureStructure owners and users are becoming increasingly aware of the liabilities and the costs of corrosion. Carrying out remedial work particularlyon highway structures, bridges and tunnels has led to a renewed interest in the use of stainless steel reinforcement, to minimize the risk of corrosion to structures exposed to marine / coastal environments, road de-icing salts, chlorides, and other harsh elements. The use of stainless steel conduit systems drastically reduces or even eliminates the need for difficult future maintenance.Power Plants, Energy and Power GenerationWhether the form of energy production is nuclear, fossil or renewable, the safety and long term value are the utmost concerns for energy and power gen- eration companies with the nuclear power industry requiring absolute reliability. These characteristics are provided by high quality stainless steel.Stainless steel is now extensively used in the power generation industry to combat corrosion, particularly at elevated temperatures. In particular, type 304 & 316 stainless are used for high temperature, strength and oxidation resistance in fossil fuelled power plants.The nuclear power industry also uses large quantities of stainless, often specified for both power gen- eration and radiation containment. Steam and gas turbines also use stainless because of its corrosion- resistant and heat-resistant qualities.800-536-22483Systems for Harsh Environments
