General Knowledge on “Stainless steel tube coil heat exchanger,low pressure drop,good heat exchanging”

Stainless Steel has good heat conductivity performance and properties .It is also healthy,and no problem to contact water or food directly.

Therefore,Stainless steel tube coil heat exchanger  is used to transfer heat in a wide variety operating conditions. coil immersion heat exchanger is more efficient than shell and tube exchangers for low flow rates. Due to their simple construction they are low in price and convenient to clean on the shell side. Thermal efficiency approximates that a true countercurrent flow type exchanger. Condenserors are used for condensation vapours cooling liquids. Condensers are made by fusing number parallel coils in a glass shell. Stainless steel  tube coil immersion heat exchanger is artificial to special requirements as to dimensional tolerances, finish and tempers for use in condensers and heat exchangers. Copper heat exchanger tubes are normally supplied in straight length in annealed half hard temper. It is not only have the stiff tolerances the most dependable dimensions throughout the tube length. The tube surface is clean both inside. Coils are made in different diameters using tubes different bores.

 Calculations of stainless steel tubing coil heat exchanger

Calculation of heat transfer area of stainless steel coil:

Heat transfer area calculation formula: F=Q/KK*△tm

F is the effective heat transfer area of the coil heat exchanger device; Q is the total heat transfer heat; k is the dirt coefficient, which generally takes 0.8-0.9; K is the heat transfer coefficient; △tm is the average temperature difference.

Setting: The specific heat of air d[j/(kg*k)], density p(kg/m³), tube thickness h(m), and the thermal conductivity of stainless steel λ[j/(m*k)]. The required heat dissipation area is S(㎡).

Average temperature difference ΔT=(82+33)/2-29=28. 5(k)

  2. Bonjour,

    I am interested in buying 4 off SS316 coiled tubing for a heat exchange application.
    Coil tube diameter 20 or 25mm
    Diameter of coiled tube 200mm
    Length of tubing to be rolled 12m

    Could you please offer a cost and your best delivery time?

  3. I´m an inventor and manufacturer of world-leading preparative gas chromatographic systems on the global market. Each system contains a number of stainless steel coils with various diameters, of the type you manufacture.
    I´m also interested in buying Stainless Steel grade 304 coil tubing very similar to the 1st coil pictured in this page, but without the thick end connectors.

    the coil dimensions I need would be :
    Coil tube diam 10mm
    height height of coiled tube 300mm
    Diameter of coiled tube 100mm

    Do you have a standard coil with approximately these dimensions

    Do you have a rough estimate of the cost?

  4. We are looking for 3/4in stainless (304) coil. 200′ in length. Can you quote me the availability and price.

  5. Salut
    I am a small hydroponics farm grower, just starting out.
    I started by using a copper coil immersed in a 500 L tank, with a 3 ton chiller using R22. But after a few weeks I noticed problems with the crops, and found out that the copper was reacting with the nutrition in the tank.

    After a lot of research, I have settled on remaking the coil out of stainless steel.
    I understand you can design these types of coils, and would like to have a quote from you.

    My current coils are in the shape of a rectangle, 750 mm long by 650 mm wide.
    There are 7 of these coils stacked to a height of 350 mm tall.

    Currently my copper tubes have an outer diameter of 11 mm, and inner diameter or 8 mm. The wall thickness is supposed to be 1.5 mm, but I measured with a vernier caliper scale and got 1 mm.

    Because steel conducts heat much less efficiently than copper, I am concerned about whether or not wall thickness of the stainless steel tube should be reduced, to lets say 1.0 mm or even 0.5 mm. What would you recommend ?

    Also, for the same reason mentioned above, would you recommend increasing the surface area, by increasing the outer diameter from 11 mm to 12 mm?

    Do you need a drawing to make a quote?


  6. I’m working for a proposal of heat exchanger device. Kindly quote best price for below details of spiral coil,details are as following:
    tube size = 12mm outer diameter x 1.5mm thickness
    Length of tube to be coil = 9meter
    diameter of coil = 76mm
    pitch between circle tubes = 20mm
    Material is SS316L
    We are going to immersed the coil in vessel which having inner diameter of 128.2mm and height of 750mm
    total quantity required is 9units.

  7. I’m interested in buying 1 Stainless Steel grade 304 coil tubing very similar to the 1st coil pictured in this page,

  11. Im looking to have a S/S heat exchanger coil made. Can you supply to me.
    Coil to have inlet and outlet at the same end and going at 90deg opposite each other.
    The outer coil OD diameter is 85mm and the pipe size is 1/2inch, and a total length of 1070mm, with 5mm between the rolls of the coil.
    And I would like a second coil inside the outer coil that is 1/2inch with 5mm between the coil, and About 5 to 10mm between the outer and inner coils.
    Can this be done

  12. Dear Sirs,

    I am looking for 3 pieces SS coil.

    Made form ½” 316 Stainless Steel.

    (D) Coil Outside Diameter = 14cm
    (L) Coil Height = 60cm
    (P) Pitch or Number of Turns = 10
    (T) Length of Outlet/Inlet = 10cm

    Inlet must be directly opposite outlet and at opposite ends of coil.

  13. I’m needing quantity three (3) Stainless steel Spiral heat exchangers per attached .pdf drawing. I’m seeking to find if you can produce in 1 inch OD with heavy wall to handle 250 degree glycol in boiler system. The ends would need to extend six (6) inches as they would need to run through a bored out compression fitting arrangement.

  14. I wish to have a heat exchanger coil made of either copper or stainless steel for for use in a scaling test rig, which we are building. I attach a sketch of the test rig and heat exchanger coil. For the moment, I wish to contruct 1 rig and carry out a proving trial. If this is successful I would want to have several coils made of both copper and stainless steel made. Possibly other companies will also be interested.

    Please come back to me to let me know whether you are able to made such a coil out of stainless steel and copper and what the likely cost will be? The tube diameter will need to be quite small from 6-10mm diameter depending on availability of material.

  15. We have a tank (1m3) with our fluid (wastewater) and we are interested in a Stainless Steel Tube Coil heat exchanger to reduce the temperature of a sample of that wastewater in order to conduct a measurement with a particular instrument.(the instrument requires that the sample is 39-40oC in order to give accurate readings).
    The fluid is waste water with suspended solids less than 15 ppm. The sample flow is 15 lt/h.
    Our fluid is at 55-60oC and we would like to cool down to 39oC. The ambient temperature is min 5oC and max 40oC.
    The waste water pressure is max 1bar.
    we do not want to cool the entire tank of wastewater, just a sample of it through a pipe. Please see attached pdf.

    we would like your suggestions for a heat exchanger that will fit the task described, followed by your best financial offer.

    meilleures salutations
