从China供应商批发进口A249 316l U Bend Pipe Stainless Steel Tubing — FOB条款

Huzhou Dongshang Stainless Steel Co., Ltd. manufactures ASTM A249 316L U-bend stainless steel tubing for heat exchanger, condenser, and chemical processing duty. The tubing covers an outer diameter range from 0.3 mm to 300 mm, wall thickness from 0.08 mm to 1.5 mm, and maximum single-piece length of 22,000 mm. Grades offered include 304, 304L, 316, and 316L, with 316L providing enhanced molybdenum-bearing corrosion resistance for chloride-rich or high-temperature service.

The mill produces both as-welded and bead-rolled (bead-hammered) variants. As-welded tubing is cold-roll formed from annealed strip and continuously welded with shielding gas appropriate to each alloy; the weld seam is visible on both interior and exterior surfaces but held to strict dimensional tolerances. Bead-rolled tubing undergoes additional cold rolling with an interior mandrel to smooth both weld surfaces, yielding a nearly invisible seam that serves as a lower-cost substitute for seamless tubing in applications demanding smooth bore and exterior surfaces.

Typical end uses for as-welded product include tubular heating elements, beverage and fluid transport systems, mechanical devices, and automotive components. Bead-rolled product is specified where interior and exterior smoothness matter, such as liquid and gas handling, fabricated fittings, and heat exchange devices. Export packaging is bundled with knitted plastic bags or wooden cases to customer request. The supplier lists FOB and CIF as available Incoterms; buyers should confirm current MOQ, lead time, and mill test certificate availability directly with Huzhou Dongshang.

Huzhou Dongshang Stainless Steel Co., Ltd. is located in the Industrial Zone, Heping Town, Huzhou, Zhejiang Province, China, with postal code 313003. The supplier holds a Harbor trust tier on the platform and currently shows a 0.00 percent response rate with zero average response hours recorded, which signals that buyers should expect to initiate contact and allow time for reply rather than rely on rapid turnaround.

The company profile does not disclose factory size, annual output, employee count, or specific clientele. What the listing does state is a product focus on cold-roll-formed stainless steel tubing in multiple grades and both as-welded and bead-rolled constructions, with dimensional flexibility from very small OD (0.3 mm) up to 300 mm and lengths to 22 metres. Buyers should verify ISO 9001 or PED certification status, mill test certificate provision, and any third-party inspection reports directly with the supplier before placing orders.
