We can produce seamless and welded stainless steel 304/304L heat exchanger tubes in a wide range of grades and sizes. Our manufacturing range for stainless steel heat exchanger tubes include tubes produced in various standards such as ASTM A213, ASTM A312, ASTM A269, ASTM A778, ASTM A789 and grades including 304/304L, 310S, 316/316L, 316Ti, 321/321H, 347/347H, 904L, Alloy 20, Duplex & Super Duplex.
  • Stainless Steel 304/304L Heat exchanger tubes are used to produce hydraulic and pneumatic lines, automotive industry, heat exchangers and air coolers. The heat exchanger tubes are manufactured by piercing process followed by pilgering/drawing. Our facilities are equipped with all the machines required to cover the process with a high quality results (piercing, pilger machines, draw benches, straightening machine, degreasing facility and solution annealing furnace).
  • A heat exchanger is a device used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.

Manufacturing Process for Stainless Steel 304/304L Heat Exchanger Tubes

All seamless stainless steel 304/304L heat exchanger tubes are manufactured by cold drawing and cold rolling process followed by annealing, straightening and testing. The tolerance of tubes produced by us in line with ASME/ASTM & EN Standards. We promise each stainless steel 304/304L heat exchanger tube that we deliver to our client will be the best in quality. All shipments include a full Test Certificate showing all required test results and verifying compliance with the order requirements.

  1. Cold Rolling – Tube rolling uses compression to reduce the size of seamless heat exchnager tubes. It utilizes one or two sets of rolls with constant cross-section grooves on the circumference of the tube. The rolls are driven by rack and pinion gears of different radii along profiled cams, completing multiple 360º rotations around the tube. Tube rolling is a very precise method of reducing very thin walled and/or smaller diameter tubes, and is often used as the final cold working step. By rolling, we’re able to achieve exceptional control over dimensional tolerances and surface finish while also minimizing material loss and improving the metal’s microstructure.
  2. Cold Drawing – Cold drawing reduces the diameter by pulling the tube through a die that is smaller than the tube. In order to fit the tube into the die, one end is swaged thereby reducing the diameter of the leading end before drawing. Next, the narrowed end is passed through the die and clamped to a drawing trolley which pulls the tube through the die.
  3. Annealing – Annealing is used to soften the metal before further cold working or fabrication processes, and improves the overall metallurgical microstructure of the tube. During tube reduction or cold drawing, it can become hard and somewhat brittle. To be able to draw the tube again, stresses formed during cold working need to be removed to return the material to its normal state. During annealing the tube is heated to a controlled temperature and soak time. Through this process the tube remains in shape, but the grains in the structure of the tube reform into a regular unstressed pattern. The resulting annealed tube is softer and suitable for redrawing
  4. Straightening – Drawing and annealing generally results in some degree of bowing, producing a slight bend in the tubing. In order to make the tubes straight, we use multiple roll mechanical straighteners to implement this procedure, Straightening can introduce slight changes to the size and mechanical properties of the tubing, so these aspects are very carefully controlled during the process.
  5. Inspection and Tests – At each manufacturing stage, heat exchanger tubes are submitted to a visual and dimensional inspection. They are also submitted to Eddy current test (straight tubes) or, if requested, to other non destructive tests in accordance with the requirements of the standards. Mechanical tests, along with flaring and flattening tests, are performed on samples of each order as per the reference standards. We inspect all lots of heat exchanger tubing before shipment to ensure that every aspect of the customer’s order has been met. Our in-house inspection and tests capabilities include:
    • Chemical Composition Test
    • Visual inspection
    • Dimensional inspection
    • Surface roughness testing
    • Eddy Current testing
    • Hydrostatic pressure testing
    • Destructive mechanical testing:
      • Yield Strength
      • Tensile Strength
      • Elongation
      • Hardness testing
      • Bending, flattening, and flaring

Prices for Stainless Steel 304/304L Heat Exchanger Tubes

Prices for stainless steel 304/304L heat exchanger tube or tubing products are directly co related to prices of the raw materials such as iron ore, metal scrap, chromium, nickel and various other alloying elements. The production cost of heat resistant stainless steel and nickel alloy heat exchanger tubes is high as they contain high amount of nickel and chromium. Meanwhile, mild steel material is among the lowest cost steel available, followed by carbon steel, 400 series stainless steels, aluminium, alloy steel, and 300 series stainless steel. Special alloys such as titanium, Inconel, Monel and Hastelloy cost very high as the nickel, chromium and moly content is very high.
