ASTM A269 TP304L Tube

SA 269 TP 304L Seamless Tubing manufacturer in India

ASTM A269 304L Stainless Steel Tubing and ASME SA 269 304L Coil Tubing in annealed, stress relieved, and pickled

These tubes are quite robust, which shows enhanced strength and also resists attacks from various reducing agents. The SA 269 TP 304L Tubing solutions are available in a wide range of dimensions, and their surface finishes are customized per application requirements.

Difference between SA 269 TP 304L Seamless and Welded Tube

Their manufacturing methods are the primary difference between seamless and welded ASTM A269 Grade TP304L Bright Annealed Tubes. The seamless ones are basically extruded and drawn from a billet, whereas the welded ones are produced from a strip, which is rolled and then welded to form a tube.

The welded SA 269 Grade TP304L ERW Tube is more affordable and available in a longer length compared to the seamless tubes. On the other hand, the seamless tubes can withstand higher pressure. The welding site of the welded tube is considered to be the weak point where leakages can occur, but the seamless tubes do not have such weak points.

What is the purpose of hydrostatic testing?

Hydrostatic testing is performed on pressure vessels, pipelines, and other components under pressure during operation to guarantee their integrity and safety.

To perform hydrostatic testing, a component is submerged in water and subjected to a predetermined amount of pressure. The part is then examined for leaks and distortion, which point to potential flaws in the component's material or structure.

The component's ability to withstand pressure surges is verified by subjecting it to a test pressure greater than its maximum anticipated operating pressure.

Hydrostatic testing is performed primarily to achieve the following goals:

1. Ensure the part is robust and find any flaws that could lead to a breakdown in operation.
2. Ensure the component won't leak, bend, or burst under the utmost strain it'll ever see in use.
3. Hydrostatic testing is required by law and by most industry standards as a means of quality control and for public safety.

How is annealing done for A269 TP304L Bright Annealed Tube?

The annealing procedure for the ASTM A269 Grade 304L Heater Tubes is done by welding, sizing, and degreasing the unit. The tube is then placed in a closed annealing chamber. The tube gets heated to a high temperature in the chamber by induction coils. The whole process takes place in the presence of inert gases in a reduced environment.

Then the red hot ASTM A269 Gr TP304L Cold Drawn Seamless Tube is taken from the closed annealing chamber, and then they are rapidly cooled. Then the tubes are finally sized and straightened.

Before conducting the procedure, the surface of the SA 269 Gr 304L Heat Exchanger Tubes should be thoroughly cleaned so as to remove any foreign particles. Also, the atmosphere where the annealing process takes place should be free from oxygen molecules.

The round-shaped ASME SA 269 304L Coil Tubing solution is stronger than the squared one. The round ASTM A269 TP 304L Stainless Steel Tube shows more resistance to bending and torsion. This is even if they have the same weight, chemical composition, and production methods.

This holds true even if the dimensions of square and round ASTM A269 304L Stainless Steel Tubing solutions are the same. The round tubes are also easy to manufacture, and they come with good fabricability.

Thus, it can be said that the round shaped tubes have the edge over the squared ones when it comes to:

• The strength
• Manufacturing cost
• Bendability

However, the square ones are preferred where there is a space constraint.
