Super Duplex Flanges
The Super Duplex Flanges supplied by Carver Water Technology are ANSI B16.5 Class 600 pipe flanges fabricated from Super Duplex stainless steel grade UNS S32750 (also known as 1.4410/2507). The flanges are offered in lap-joint design with stub ends and are available in nominal pipe sizes of 6 in, 8 in and 18 in. The material provides a typical yield strength of approximately 550 MPa and superior resistance to chloride‑induced stress corrosion cracking.
Carver Water Technology indicates that the flanges are manufactured to meet the requirements of offshore platforms, seawater desalination plants and aggressive chemical processing environments. The Super Duplex alloy is characterised by a dual‑phase microstructure that delivers high tensile strength and excellent pitting resistance, which is standard for this grade in the oil‑and‑gas sector. The supplier does not list additional surface treatments, but the material’s typical hardness lies in the range 250 - 280 HB.
Importers can request bulk quantities for international shipment; the listing does not specify packaging details, incoterms or payment conditions, so these should be negotiated directly with Carver Water Technology. The flanges are suitable for distributors serving the petrochemical, marine and water‑treatment industries, and the supplier notes that they are commonly packed in wooden crates with protective dunnage for sea freight.

Sourcing Super Duplex Flanges from Carver Water Technology - United States Import Guide
Before committing to purchase, importers should obtain the mill test report, chemical analysis and any applicable ASME or NACE certification that confirms the Super Duplex grade and Class 600 compliance. Verifying the bolt pattern, flange dimensions and material heat‑treatment records against project specifications reduces the risk of non‑conformance during installation.
Logistics for these flanges typically involve sea freight in wooden crates with adequate dunnage to protect the stub ends. The supplier does not disclose incoterms, lead time or payment terms, so buyers must negotiate these details directly, confirming whether FOB, CIF or DAP terms apply and what shipping documents will accompany the cargo. A common lead time for bulk stainless‑steel flange orders ranges from three to five weeks, but exact timing should be confirmed with Carver Water Technology.
Quality control is best achieved by arranging a third‑party inspection at the manufacturing site or upon arrival. Request non‑destructive testing results, dimensional verification and a visual weld inspection of the stub ends. Ensure that the packaging is intact, that all markings match the order specifications and that the required certificates accompany the shipment before releasing payment.
