Stainless Steel Welded Tube Bright Annealed A249 TP316L 1.4404 ET HT

YUHONG GROUP deal with Stainless steel pipe and tube already more than 10 years, every year sell more than 80000 tons of stainless steel seamless pipe and tube. Our client already cover more than 45 countries.

ASTM A249 Specfication covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels. ASTM A249 material shall conform to the prescribed tensile and hardness properties such as tensile strength, yield strength, elongation, and Rockwell hardness number.

Standard Specification for Welded Austenitic Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes of A 249 / SA 249

1.A249/SA249

A249 is a specification from the American Society for Testing and Materials (ASTM) for welded austenitic stainless steel tubes.
These tubes are commonly used in heat exchangers, boilers, and condensers.
The specification ensures requirements for quality, dimensions, and testing methods for these tubes.

2.Bright Annealed (BA)

Bright annealed refers to a heat treatment process where the tube is annealed (heated and cooled) in a controlled atmosphere to achieve:
- A smooth, bright, and reflective finish.
- Improved corrosion resistance and a cleaner surface.
Often used in industries requiring a high-quality surface finish, such as pharmaceutical, food processing, or decorative applications.

3.Typical Applications

Heat exchangers in power plants, chemical processing, and desalination plants.
Fluid transfer in pharmaceutical and food industries.
High-corrosion environments, such as marine or offshore applications.

Quality Control :

Corrosion Test	Conducted only when specially requested by the client
Chemical Analysis	Test done as per required quality standards
Destructive / Mechanical Testing	Tensile \| Hardness \| Flattening \| Flare \| Flange
Reverse-bend and Re. flat tests	Carried out in full compliance with relevant standards & ASTM A-450 and A-530 norms, which ensures trouble-free expansion, welding & use at customers end
Eddy Current Testing	Done to detect homogeneities in subsurface by using Digital Flaw-mark Testing System
Hydrostatic Testing	100% Hydrostatic Testing carried out according to ASTM-A 450 norms for checking tube leakage, and biggest pressure we can support 20Mpa/7s .
Air Under Pressure Test	To check any evidence of air leakage
Visual Inspection	After passivation, every single length of tubes & pipes is subjected to thorough visual inspection by trained staff for detecting surface flaws & other imperfections
