Internally Optimized Multi Lead Rifled Steel Tube - China

Internally multi-lead rifled steel tubes shall be applied on the water wall of power plant boilers, as the main component for heat exchange, the rotary movement of water caused by internal spiral ribs can eliminate steam film on the tube's inner surface and thus achieve nucleate boiling.

There are two types of internally ribbed tubes: Multi-lead rifled tubes and Optimized multi-lead rifled tubes.

Multi-lead rifled tubes are grouped into two types, designated Type A and Type B, with a 30-degree helix angle, these unique products can improve thermal efficiency by 30%, in comparison to bare tubes.

The optimized multi-lead rifled tube is a newly-developed ribbed tube, its helix angle is up to 40 degrees and more, thus can further improve thermal efficiency by 20% in comparison with ordinary multi-lead rifled tubes, which certainly have better heat transmission performance;

In detail see heat-transfer characteristics below, including bare tubes, multi-lead rifled tubes, and optimized multi-lead rifled tubes: Multi-lead rifled steel tubes main steel grades:

on the inner surface of the tube and raise thermal efficiency in the furnace walls.

Rifled tubes in a conventional boiler provide a larger margin of safety for natural circulation and assisted circulation and many economical advantages such as:

- Reduction of weight for downcomers, headers, drum, and connecting pipe

- Reduction of pumps power

- Reduction of framework weight

• 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.
