Qingdao Yingli Machinery Co., Ltd. supplies stainless steel flanges made from grades 304 and 316 as stated in the listing. The flanges are manufactured to ASME/ANSI B16.5 specifications and cover pressure classes 150, 300, 400, 600, 900, 1500 and 2500. Available types include welding‑neck, slip‑on, blind, socket‑weld, threaded, lap‑joint and ring‑type joint designs. Each unit is shipped on a wooden pallet or crate to protect the dimensions during international transit.
In the pipe‑fitting market, 304 stainless steel provides good corrosion resistance in water and atmospheric environments, while 316 offers enhanced resistance to chlorides. Typical flange diameters range from DN15 to DN2000, with bolt‑hole circles matching the corresponding standard series. Industry practice tolerates a flange thickness deviation of ±0.5 mm and a bolt‑hole positional tolerance of ±0.2 mm, which are considered typical for these classes. Surface finish is commonly specified as a 2B mill finish, a standard that facilitates gasket sealing.
Buyers such as oil‑field contractors, petrochemical plants and chemical processors use these flanges to create leak‑proof pipe connections. Pricing is generally quoted per unit or per metric ton, and the supplier indicates that packaging is performed in wooden pallets or crates for export. Importers should confirm lead‑time, Incoterms and payment conditions directly with the supplier before placing an order.

Before confirming a purchase, importers should verify the exact flange size, pressure class and material grade required for their pipeline. Request the supplier’s latest product catalogue or CAD drawings to ensure the bolt‑hole pattern matches the intended connection. It is also advisable to ask for a mill test report that confirms compliance with the cited ASME/ANSI standards. Clarifying these details reduces the risk of mismatched components.
Logistical arrangements need explicit agreement on Incoterms, as the supplier does not disclose them in the listing. Typical shipments are sent in wooden pallets or crates, so confirm the pallet dimensions and total weight to avoid carrier restrictions. Lead‑time can vary with the chosen grade and size; ask the supplier for an estimated production and dispatch schedule. Payment terms such as T/T, L/C or open‑account should be settled before shipment.
Quality assurance for stainless steel flanges usually involves visual inspection, dimensional checks and non‑destructive testing where required. Request a pre‑shipment inspection report and, if necessary, arrange a third‑party audit at the manufacturing site. Documentation such as a material certificate, pressure test certificate and conformity declaration will support customs clearance and downstream acceptance. Maintaining these records helps ensure the flange meets the project specifications.
