ASTM A269 TP304L Stainless Steel Bright Annealed Seamless Pipe

If you are seeking high-purity ASTM A269 TP304L Bright Annealed (BA) seamless tubing, we offer premium-quality seamless tubes-fully compliant with ASTM A269 and ASME SA269 standards,specifically engineered to address common issues in precision piping systems, such as surface oxidation, residual impurities, poor weldability, and intergranular corrosion.

Our ASTM A269 TP304L round tubing is manufactured using vacuum induction-melted billets. Through precision cold drawing and rolling, we ensure a consistent inner wall roughness of Ra ≤ 0.4μm (15μin), effectively reducing the risk of particulate retention by over 40%. The result is a smooth, mirror-like finish free of oxide layers, characterized by stable hardness as well as excellent formability and bending properties.

We strictly control the carbon content to below 0.030% to completely eliminate the risk of intergranular corrosion within the heat-affected zones of welds. Furthermore, every ASTM A269 TP304L tube undergoes 100% eddy current testing and a 20 MPa airtightness pressure test. With an ultra-tight radial tolerance of ±0.05mm, our tubing features precise dimensional control suitable for continuous operation in environments reaching up to 425°C. It is widely utilized in semiconductor piping, pharmaceutical systems, food and beverage equipment, instrumentation lines, hydraulic systems, and high-purity fluid transport applications.

inspection

laring Test (Seamless Tubes)
One test shall be made on specimens from one end of one tube from each lot of finished tubes.

Flange Test (Welded Tubes)
One test shall be made on specimens from one end of one tube from each lot of finished tubes.

Reverse flattening Test
For welded tubes, one reverse flattening test shall be made on a specimen from each 1500ft(460m) of finished tubing. Coiled tubing greater than 1500ft(450m) in length shall be sampled at both ends, a coil must be continuous without any circumferential butt welds.

Hydrostatic or Nondestructive Testing
Each pipe shall be subjected to the nondestructive electric test or the hydrostatic test.
