ASTM A213/A213M -17 Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes. This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes. Grades containing the letter H in their designation have requirements different from those of similar grades not containing the letter H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements. The tubes shall be made by the seamless process and shall be either hot finished or cold finished, as specified. Grade TP347HFG shall be cold finished. Heat treatment shall be done separately and in addition to heating for hot forming. The ferritic alloy and ferritic stainless steels shall be reheated. On the other hand, austenitic stainless steel tubes shall be furnished in the heat-treated condition. Alternatively, immediately after hot forming, while the temperature of the tubes is not less than the minimum solution temperature, tubes may be individually quenched in water or rapidly cooled by other means. Tension test, hardness test, flattening test, and flaring test shall be done to each tube. Also, each tube shall be subjected to the nondestructive electric test or hydrostatic test. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Seamless Tube Manufacturing Process
This all seems to have changed now, thankfully because of the advent of new technological advancements and developments. Due to this, many new processes have surfaced that makes the whole manufacturing process of seamless tubes, easy and cost-effective. But the most popular process that has caught on with many manufacturers in the process of continuous tube mill. No forge welding or filler metal is used in this new technique.
- Preparing the stainless steel sheets
The stainless steel sheets undergo several checks before getting picked to roll. While preparing them, the first step is to trim them around the edges.
- Rolling through rollers
The sheets are then passed through many rollers to match the required size. In this step, you can see the sheets progressing into tubular shapes.
- Rollers Through the fitted welding machine
In this step, the tubular shape has to go through a fitted welding machine. The inside of these tubular shapes, i.e., the weld beads and scraps are removed, thus giving you perfectly rolled tubes.
- Cleaning and heating of rolled seamless tubes
After the stainless sheets have a basic rolled structure, it goes through the process of cleaning and heating. This depends upon the clients’ requirements. The stainless steel tubes are cleaned thoroughly to remove dirt before the heating process begins. Heating is used to remove the possible stress on the seamless tubes and let it have a seamless shape. The tubular shape is rolled in a hot furnace that has temperature controllers and recorders. The heating process helps the tubes to be straightened and open to pickling and removing the scales from its surface.
- The cold-drawing process
Many clients have a peculiar tube requirement that will not match the seamless tubes rolled out directly from the mills. For this reason, another process of cold-drawing is to be performed to achieve the desired size.
To manufacture cold-drawn seamless tubes, the manufacturer first coats the tube with soap and oxalic solution. The solution helps to reduce the friction caused due to this process, by acting as a lubricant. Later, the seamless tubes are benched with the help of Die plugs.
- Final touches
The final touches include ink jet marking on the seamless tubes, that educates the exporters about the tube’s grade, material, heat number, size, and a third party inspection stamp. Followed right after this are several stringent quality checks and appropriate packaging, making these seamless tubes ready for dispatch.
There are several industries that need seamless tubes in different alloys to have varied tensile strength. Thus many manufacturers produce the alloy steel Seamless tube. The most popular among these alloy steel seamless tubes are a carbon steel seamless tube.
