Super Duplex Flanges
Raquel Sorongclo offers Super Duplex Flanges that combine a 316 stainless‑steel lap joint ring with a super duplex UNS S32750 stub end. The flanges are rated Class 600 and conform to ASTM A182 and ASME B16.5 standards. Available nominal pipe sizes include 6‑inch, 8‑inch and 18‑inch lap‑joint configurations, with quantities listed in the source data. Each unit is supplied as a matched lap joint flange and stub end assembly for high‑pressure service.
The 316 SS ring provides good formability while the super duplex body delivers superior resistance to chloride‑induced stress corrosion, a key requirement in offshore and desalination environments. Typical industry practice for Class 600 flanges includes a pressure rating of up to 600 psi and a temperature span from - 50 °C to about 300 °C. Standard dimensions such as bolt circle diameter and flange thickness follow the ASME B16.5 tolerance chart, ensuring interchangeability with existing pipework.
These components are most commonly purchased by EPC contractors, refinery operators and plant engineers who need reliable connections for oil‑and‑gas pipelines, chemical processing units and seawater desalination plants. Raquel Sorongclo ships the flanges in bulk, and buyers should confirm the minimum order quantity, preferred Incoterm and expected lead time directly with the supplier. All trade terms are negotiable once the technical specifications are agreed.

Sourcing Super Duplex Flanges from Raquel Sorongclo - United States Import Guide
Before placing an order, confirm that the flanges are accompanied by material test certificates and a compliance declaration for ASTM A182 and ASME B16.5. Request a mill test report (MTR) for both the 316 ring and the super duplex body to verify chemical composition and mechanical properties. These documents are essential for quality assurance and downstream engineering approvals.
Discuss logistics early to avoid misunderstandings about shipping terms. Ask the supplier which Incoterms they can offer, typical lead times for the selected sizes, and whether they can arrange container loading from the Tampa port. Clarify payment conditions, such as whether a letter of credit or advance payment is required, and ensure these terms are documented in the purchase agreement.
Plan for on‑site inspection or third‑party testing upon arrival. Common checks include visual inspection for surface defects, dimensional verification against the ASME B16.5 chart, and non‑destructive testing (e.g., magnetic particle inspection) for weld integrity. Request the supplier to provide a certificate of conformity and any additional documentation required for customs clearance in the destination country.
