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.

Before ordering, verify that Huzhou Dongshang can supply the exact grade, wall thickness, and tube construction (as-welded or bead-rolled) your heat exchanger or process design specifies. Request a current mill test certificate sample, confirm ASTM A249 compliance, and ask whether third-party inspection by SGS, BV, or another recognised body is available. Check that the supplier's quality plan includes dimensional inspection, hydrostatic or eddy current testing, and passivation if required for your end market.
Confirm Incoterms, with FOB and CIF listed as available but exact port of shipment unspecified in the source data. Sea freight from Chinese ports to most destinations runs 14-35 days depending on route and transshipment; buyers should factor in customs clearance and inland haulage. Ask the supplier for typical production lead time, whether stock exists for common sizes, and what payment terms they accept. Letter of credit or secure escrow terms may be advisable given the zero recorded response rate and the need to establish trading confidence.
On arrival, inspect bundles for moisture damage, salt contamination, or mechanical deformation that could initiate pitting corrosion on 316L surfaces. Verify random sample dimensions against the mill certificate using calibrated micrometres and a plug gauge for internal diameter if bead-rolled smoothness is specified. Retain samples for independent spectrographic analysis if alloy verification is critical. Ensure all documentation, including packing list, commercial invoice, certificate of origin, and any preferential trade certificate (Form E, COO), matches the shipment exactly to avoid customs delays.
