304L stainless steel tube
What does the L in 304L stainless steel tube stand for?
The L in the 304L Stainless Steel Tube stands for extra low carbon. For grade 304, the max carbon content is 0.08% whereas for 304L, it is 0.08%. This means, the 304L Tubing is weaker than 304 tube, but it helps minimize carbide precipitate during welding process. Thus, there is no need to anneal 304L tubes joints which save time and effort.

Difference between reheater and stainless steel 304L superheater tubes
SA 213 TP304L superheater and reheater tubes are both capable of handling high temperatures and pressures. However, the main difference between reheater and superheater ASTM A213 TP304L tubes is their steam pressure. Superheaters can handle much higher outlet pressure in boilers compared to reheaters.

Is SS 304L seamless tube stronger than welded?
The SS 304L Seamless Tube comes with better pressure capacity and strength than the welded tubes of the ss 304L grade. This is why the seamless 304L Tubing solutions are used in various high pressure equipment, in the thermal and boiler industries. They also do not have the weak welded seam of the SS 304L Welded Tubes, which is generally a weak point and might affect its overall performance quality.

Why stainless steel 304L tubes are used for heat exchanger?
- The Stainless Steel 304L Tubes material is very reliable and durable
- It can effectively resist corrosion, and the deposition of various mineral residues is also minimized.
- The 304L tubes show dimensional accuracy and they can installed easily.
However, it is essential to select a reliable 304L Stainless Steel Tubing solution manufacturer. Or else the welded joints of the tubes in the heat exchanger can become a weak point which might to performance failure.
3 point to recognize if your 304L tubing is erw or seamless?
- The ERW 304L SS Tubing solutions are manufactured by firstly rolling the metal and then welding it across the length (longitudinally). The seamless tubes are manufactured by extruding the material to the desired length.
- The ERW 304L Stainless Steel Square Tubing have seams or joints running parallel to their length, whereas the seamless pipes have no such joints.
- Due to the absence of any weak seam in the seamless Inox 1.4306 Tubes, they have higher strength. This is why seamless tubes are preferred in various high pressure applications. It includes services in hydrocarbon refineries and industries, oil and gas transportation, hydraulic cylinders, etc. The ASTM A554 TP 304L ERW tubes are used for low to medium pressure applications. They are mainly used for the transportation of water, oil, etc.
