DSA Flange
The DSA Flange offered by Yulin International Corporation is a double‑stud adapter designed to join piping components with mismatched nominal sizes, pressure ratings or face configurations. The product is manufactured from carbon steel as a standard option, with stainless steel grades 304/316 provided as typical variants; Inconel 625 is also available for high‑temperature service. The flange conforms to API 6A and API Spec Q1, and meets ANSI/ASME and DIN dimensional standards, ensuring compatibility with a broad selection of industry piping systems.
Typical pressure ratings cover class 150 through class 2500, corresponding to up to 1500 psi, while the usual temperature operating window spans - 20 °C to 200 °C. Standard dimensions include diameters from 100 mm to 2000 mm and wall thicknesses of 10‑50 mm, with double‑stud configurations that incorporate tap‑end studs and matching nuts. Yulin International supplies the flanges with stainless‑steel 316L or Inconel 625 corrosion‑resistant ring grooves when specified, and packages the units on standard pallets of twenty pieces for efficient handling.
These adapters are widely used in oil and gas production, petrochemical processing, and other high‑pressure industrial applications where flange size conversion is required. The supplier can provide custom thicknesses and material selections to meet specific project standards; buyers should verify minimum order quantities, lead‑time estimates and preferred Incoterms directly with Yulin International before confirming a purchase.

Sourcing DSA Flange from Yulin International Corporation - China Import Guide
Importers should first obtain the material test certificates that confirm the exact steel grade or stainless specification, as well as any heat‑treatment records for Inconel versions. Requesting a dimensional inspection report will help verify that the flange meets the required API 6A tolerances before committing to a larger purchase.
Logistical details need to be clarified with Yulin International, including the chosen Incoterm (FOB Shanghai, CIF, etc.), the expected lead time for custom thicknesses, and the loading port. Buyers should also confirm whether the standard pallet packaging meets their freight requirements or if bulk crates are preferred for larger dimensions.
To maintain product integrity, arrange third‑party inspection at the factory focusing on material composition, dimensional accuracy and pressure‑rating verification. Obtaining the supplier’s inspection certificates and any relevant compliance documents will streamline customs clearance and ensure the flange performs reliably in high‑pressure service.
