A2 - B2 - C2

- ASME SA556 Sect.

II Gr.

A2 - B2 - C2 "U" Bent tubes in accordance with the standards detailed in table 1, part A can be requested.

The bent area can be subject to stress-relieving heat treatment by the joule effect in an inert atmosphere.

- Minimum radius treated = 28 mm.

- Maximum radius treated = 750 mm.

2 - Dimensions and lengths

Tubes with the following external diameters in mm can be bent upon agreement: 15, 8 - 16, 0 - 17, 0 - 18, 0 - 19, 05 - 20, 0 - 21, 3 - 25, 4 - 26, 7 - 31, 8 -38, 1 - - The minimum feasible radius is: 1, 5 x external diameter

- The maximum feasible radius is 1500 mm.

3 - Tolerances

Tolerances (diameter and wall thickness) according to ASTM A 556 or given in the standards detailed in table 1 point A are respected.

Bending tolerances:

The tolerances stipulated in ASTM A 556 are respected.

Minimum wall thickness tolerances in the bent area conforming to the TEMA standard "Class R heat exchangers" can be requested or in accordance with specific requests.

4 - Checks and test

All the mechanical and technological tests stipulated in the cited standards are carried out.

Leak tightness test: electromagnetic test (Eddy Current) is performed on straight tubes.

Hydrostatic test on bent tubes is performed only if expressly requested, specifying the test pressure.

Standard Technical Range

- OD 9.5mm - 38.1mm

- WT up to 6.35mm

- Bending radii 1.25 x OD up to 1700mm

- Bends can be supplied in accordance with TEMA R / ASTM SA/A556

- Leg length up to 15000mm

- Heat treatment where required by the electric furnace or direct resistance

- Hydrotesting up to 10, 000 psi Additional Testing

- Dye penetrant of U bend area

- PMI testing

- Heat Treatment We are equipped to carry out heat treatment of bends plus a minimum of 150mm of the leg.

Heat treatment equipment is computer controlled with the added facility of data recording.

An argon protective atmosphere is used inside stainless and special alloy tubes during heat treatment.

We can provide all types of annealing; solution annealing and stress relieving.

Measuring, Cutting, Deburring, and Cleaning U bends are produced, controlled, and measured fully in accordance with relevant standards.

All tubes are cut to the specified leg lengths, ends deburred and the bores are internally cleaned with dried air.

Packing

For road freight in timber fingers or skids.

In strong open or closed wooden boxes depending destination.

Each bundle is protected with plastic sheets.

Customers can provide their packing or Salem can prepare a packing plan.

Detailed packing lists are attached to wooden cases to give quick and clear identification of contents.

• 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.
