Stainless Steel Ep Tubes
Shangdun Special Materials Co.Ltd. supplies stainless steel electro‑polished (EP) tubes made from 304L and 316L grades. The tubes feature a surface roughness (Ra) below 0.4 µm and are offered in a range of outer diameters from 3.175 mm (1/8 in) to 25.4 mm (1 in) with corresponding wall thicknesses between 0.51 mm and 1.65 mm. Each size is listed with the exact OD‑WT pairs provided by the supplier, for example 1/8 in OD with 0.51 mm or 0.71 mm wall. The product description highlights stable chemical properties, high pressure‑proof ability and low resistance.
Electro‑polishing removes surface imperfections, delivering a mirror‑like finish that reduces particle adhesion in clean‑room environments. Both 304L and 316L grades offer excellent corrosion resistance against chlorides and acids, meeting typical ASTM A240 requirements for sanitary applications. The mechanical properties include a hardness range of HRB 75 to 580 and a tensile strength that can be adjusted through heat treatment in a reducing atmosphere. In the industry, EP tubes are commonly specified for pressure ratings up to 1.6 MPa as a typical design limit.
These tubes are widely used in semiconductor fabs, pharmaceutical processing equipment, medical device assemblies and specialised gas distribution networks. Importers normally request the exact OD‑WT combination, confirm the electro‑polished surface specification and verify compliance with ISO 14644 clean‑room standards. Trade terms, minimum order quantities and lead times are not disclosed in the listing and should be confirmed directly with Shangdun. The supplier operates from Shisheng Industrial Park in Jiaxing, Zhejiang, China and is listed as an imported tier with a harbor trust tier.

Sourcing Stainless Steel Ep Tubes from Shangdun Special Materials Co.Ltd. - China Import Guide
Before placing an order, importers should verify that the tube grade (304L or 316L) matches the required corrosion‑resistance level, and that the outer diameter and wall‑thickness pair correspond to the design drawings. Request a surface‑profile report to ensure the Ra < 0.4 µm finish, and obtain a mill test report confirming chemical composition and mechanical properties. Any deviation from these specifications should be clarified with Shangdun prior to contract finalisation.
Logistics for stainless‑steel EP tubes are typically arranged under CIF or FOB terms at the nearest Chinese port, often Shanghai or Ningbo. Because the supplier’s response metrics are not published, buyers should ask for estimated lead times and shipping schedules early in the negotiation. Common payment methods include T/T in advance or L/C at sight, but the exact conditions must be agreed with the supplier before shipment.
Quality assurance generally involves third‑party inspection of dimensions, wall thickness and surface finish before loading. Importers are advised to specify an independent pre‑shipment inspection according to ISO 17020 standards and to request the inspection report together with the certificate of conformity. Documentation such as the mill test report, surface‑roughness certificate and a declaration of compliance with ISO 14644 should accompany the commercial invoice and packing list.
