ASME SA249 TP316Ti bright annealed Stainless Steel Welded Tubing

GNEE is a renowned manufacturer, exporter, distributor, stockist, and supplier of bright annealed stainless steel pipes. Our products meet national and international raw material quality standards.

Our ASME SA249 TP316Ti bright annealed stainless steel welded pipes are corrosion-resistant, welded pipes that comply with the ASME SA249 standard. Made from titanium-stabilized 316 stainless steel (TP316Ti), they achieve a bright, clean, and smooth surface after annealing. This specific grade is designed for high-temperature, corrosive environments and is suitable for applications such as boilers, heat exchangers, and condensers.

ASME SA249 TP316Ti stainless steel welded pipes are available in sizes from 6-610mm in outer diameter and 0.5-12mm in wall thickness. They are delivered with a BA (bright annealed) surface finish and must pass hydrostatic and eddy current testing.Email: sales@gneestainless.com

We offer TP316 ti welded stainless steel tubes conforming to ASME SA 249 / ASTM A249, outside diameter and wall thickness tolerances should be controlled according to SA249 and ASTM A1016, aiming to offer closer tolerances welded tubes.

 

Eddy Current And Air Under Water Test
The tests include destructive tests and nondestructive tests. For TP316ti welded tubes, eddy current test and air underwater test are usually conducted according to standard.

Mechanical Properties
Mechanical properties tests are also required for checking the quality, such as flattening test, flaring test, flange test, and reverse bend test, they are all destructive tests.

 Packaging and Marking:
Packaged in bales or laminated wooden crates, wrapped in plastic, and appropriately protected to ensure seaworthiness for transport, or as required.
Marking must comply with Specification A1016/A1016M. Marking must include information on whether the pipe is hot-finished or cold-finished, including but not limited to: standard, grade, size, heat number, and batch number.
