Duplex Steel Tube - China

Duplex stainless steel offers excellent resistance to corrosion and very high mechanical strength.

The high corrosion resistance of duplex stainless steel ensures significantly more uptime than carbon steel and conventional stainless steel, while the mechanical strength allows for lighter constructions, a more compact system design, and less welding.

Duplex stainless steels are extremely corrosion resistant, and work hardenable alloys.

Duplex stainless steel plate contains relatively high levels of chromium (between 18% and 28%) and low to moderate amounts of nickel (between 1.5% and 8%).

The high corrosion resistance and excellent mechanical properties of duplex stainless steels can be attributed to their chemical composition and balanced (duplex) microstructure of approximately equal volume percentages of ferrite and austenite.

Because of this duplex nature, it will display properties characteristic of both austenitic and ferritic stainless steels.

Duplex stainless steels are in most cases, tougher than ferritic stainless steels.

The strengths of duplex stainless steels can in some cases be double that of austenitic stainless steels.

Due to their high strength and corrosion resistance properties, Duplex Stainless Steels are used in a variety of applications such as:

- Pressure vessels, reactor tanks, and heat exchangers

- Desalination plants and seawater systems

- Water transmission pipes

- Rotors, impellers, and shafts in industrial equipment

- Stock washers and other equipment for the pulp and paper industry

- Absorber towers, and FGD systems for air pollution control

- Phosphoric acid production

- Food, oil and gas, mining, and architectural applications

- Biofuels plants Features:

- Superior resistance to general and local corrosion, especially to stress corrosion, pitting corrosion, crevice corrosion, corrosion fatigue, and abrasion & corrosion.

- Good weldability

- Good mechanical properties

- Excellent intergranular corrosion resistance

- High cost-effectiveness, long lifetime

• Business Description: Shanghai T.S. Industrial Co., Ltd focuses on Finned Tubes, Fin Tube, and Finned Pipe used in Heat Exchangers, Boiler Economizers, Coolers, and Heaters.
  
  We supply custom fin tubes and finned pipes in various material configurations that will increase the heat exchangers' heat transfer rate and reduce operating costs.
  
  With an advanced high-frequency resistance welding finned tube production line, an annual production capacity of up to 4000 tons, the specifications of phi 22-273mm finned tube, according to national standards or customer requirements standard production.
  
  The company produces finned tubes (square fin tube, circular finned tube, spiral fin tube, H type finned tube, longitudinal fin tube, corrugated fin tube, spiral serrated fin tube, needle-shaped fin tube, plate-shaped fin tube, inner fin tube) that can be applied to the boiler, air preheater, etc.
  
  Fin tubes or called finned tubes are a major component for various heat recovery systems.
  
  The close connection between the Finning operation and the manufacturing plant allows significant savings in packaging and freight as well as working capital reduction as a result of a “just-in-time” supply chain.
  
  T.S. Industrial Supply and produce to custom requirement finned tubes.
  
  For high-frequency resistance welding finned tube.
  
  The fin, either solid or serrated, in carbon, alloy, or stainless steel is helically wound around the tube and resistance welded.
  
  For Extruded Finned Tube, the Base tube can be carbon steel, alloy Tube, and stainless steel, while the fin can be aluminum and copper alloy.
  
  Typical product, we also produce extruded serrated finned tubes.
  
  For Bending, We can be on the bare tube and also can be over the fin, is performed on-site with custom-designed duplex benders.
  
  In our typical finned tube supply range, we supply both extruded fin tubes and helical welded finned tubes, which are mainly used for the heat transfer industry.
  
  Specific types such as Embedded Fin Tube also called G Type Fin Tube, L Fin Tube, LL Finned Tube, KL Finned Type also call knurled Finned Tube, Extruded Fin Tubes, Extruded Serrated Fin Tube, Square Fin Pipe also call H Fin Tube, Rectangular Fin Pipes also called Double H Fin Tube, Longitudinal Finned Tubes, Studded Tube and Nailhead Pipe, High-Frequency Welded Serrated Fin Tube, High-Frequency Welded Solid Fin Tube.
  
  T.S. Industrial privately owned company and finned tube manufacturer.
  
  We are not owned by, nor do we own, any steel producers.
  
  Our independence from steel producers ensures that we are objective in matching exact customer needs in terms of quality, specifications, and delivery.
  
  T.
  
  S Industrial provides finned pipes products and services to the power plants, petrochemical industries, boiler & heat exchangers, nuclear stations, paper, shipbuilding sectors as well as refrigerating industries.
  
  Incorporated with manufacturers and fabricators in China, we can supply in accordance with most international standards with high-qualified and cost-effective products.
  
  Our main strength lies in the heat exchanger tubular, especially finned tubes, which can be long up to twenty meters, and usually delivered in U-bent form.
  
  We are confident that our expertise in this field will bring you high-value-added products & services, and we are ready anytime to team up with your finned tube solutions.
