Manufacturing Process for Seamless Steel Tubing

All seamless steel 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 instrumentation 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 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 – We inspect all lots of seamless 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 Seamless Tube/Tubing

Prices for seamless tubing materials 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 plates 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.

We are also regularly publishing our price list for various steel products on our blog.
