ASME SA213 TP321 Bright Tube BA For High Temperature In The Food And Pharmaceutical Industries



ASME SA213 TP321 bright tube is a high-standard seamless austenitic stainless steel tube used in critical equipment such as boilers and pressure vessels. Made of titanium (Ti)-stabilized 321 stainless steel, it offers excellent resistance to intergranular corrosion and excellent high-temperature performance.

It is widely used in critical equipment such as power plant boilers, the petrochemical industry, and the food and pharmaceutical industries, which require extremely high material properties and surface finishes. Through a bright annealing (BA) process, its surface is free of scale and decarburization, forming an extremely pure, dense, and uniform chromium passivation film.

This not only provides a superior corrosion resistance compared to ordinary pickled tubes, but also offers a smooth, flawless surface that resists contaminant adhesion and residue, making it extremely easy to clean and sterilize, meeting the requirements of industries such as food, pharmaceuticals, and semiconductors.

Choose pickled tube when:

Cost is the primary consideration.
Used in general industrial environments, such as chemical piping and structural support components.
Low aesthetic requirements.
The pipe may undergo subsequent processing, such as welding and bending, which may damage the surface.



Choose bright annealed (BA) tube when:

Extremely high corrosion resistance is required, especially in harsh environments such as the chemical and marine industries.
High cleanliness requirements to prevent product contamination, such as in the food, pharmaceutical, and semiconductor industries.
Aesthetics are important, such as for visible decoration or high-end equipment components.
Media tend to deposit or adhere to the surface, and a smooth surface is easier to clean and maintain (such as food and dairy piping)







Application

Boiler superheater/reheater tubes

Economizer tube bundles

U-tube heat exchangers (TEMA standard)

Hydrogenation reactor feed/discharge lines

Auxiliary steam generator tube bundles

High-temperature molten salt heat exchangers (solar thermal power generation)
