Industrial Stainless Steel Seamless Tube A213 TP304 High Strength For Heat Exchanger
In the damp industrial or coastal atmospheres of Europe, they perform better than TP 304/304L and ferritic grades. In low temperature seawater they offer limited resistance to pitting but are susceptible to crevice attack. Their short- and long-time properties at elevated temperatures are also superior to those of comparable TP304/304L grades.
Specification ASTM A213 / SA213: Standard Specification for Seamless Ferritic and Austenitic Alloy- Steel Boiler, Superheater and Stainless Steel Heat Exchanger Tubes.
ASTM A249 / A249M: Standard Specification for Welded Austenitic Steel Boiler, Superheater
Heat-Exchanger, and Condenser Tubes.
Other Standard: DIN 17456 , DIN 17458, EN10216-5, GOST 9940-81, GOST 9941-81, JIS-G3463...
Final Finishing: Solution Annealed & Pickled/Bright Annealed.
Type of Tubes: U-bend & Straight.
Some of the quality tests carried out by us includes
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
Supplementary Testing : Apart from the above mentioned tests, we also carry out on the manufactured products supplementary testing. The tests conducted under this include:
