Flange
The flanges supplied by Zhangqiu Ruiye Mechanical Co., Ltd. are manufactured from multiple material grades including A105, SS400, S235JRG2, P25GH, C22.8, Q235, 304/L, and 316/L. These materials are selected for applications requiring resistance to corrosion, high temperature, or pressure, with each grade meeting its respective international standard. Dimensions follow ASME B16.5 for nominal sizes from 1/2 inch to 24 inches.
Carbon steel grades like A105 and Q235 are forged with controlled cooling to ensure grain structure integrity, while austenitic stainless grades 304/L and 316/L are solution annealed to restore corrosion resistance after forming. Typical wall thicknesses and bolt hole patterns conform to ASME B16.5, with face types including raised face and ring-type joint. No coating or plating is applied unless specified by the buyer.
These flanges are used in water treatment systems, oil and gas pipelines, and industrial construction where reliable pipe connections are required. Buyers include municipal contractors, plant maintenance teams, and equipment integrators. Standard delivery is within 30 days for orders up to 2000 units. Packaging is designed for international shipping, with protective wrapping and wooden crates. Trade terms include FOB and CIF, but minimum order quantities are not stated and must be confirmed.

Sourcing Flange from Zhangqiu Ruiye Mechanical Co., Ltd. - China Import Guide
Verify material certifications for each grade before ordering, especially for stainless steel variants. Request a material test report (MTR) that includes chemical composition, mechanical properties, and heat treatment details. Confirm that the flange dimensions match ASME B16.5 drawings. Do not accept generic certifications without batch-specific traceability.
Lead time is stated as 30 days for orders up to 2000 units, but this may vary with material availability. Confirm Incoterms as FOB or CIF and clarify whether packaging includes desiccants for moisture-sensitive shipments. Payment terms like T/T or L/C are implied but not specified; negotiate terms directly with the supplier to avoid delays.
Perform incoming inspection using calipers, micrometers, and surface roughness testers. Check for surface defects, correct bolt hole count, and face flatness. For stainless flanges, conduct a magnetic test to detect ferritic contamination. Retain a sample from each shipment for future reference. Ensure all documentation includes the supplier’s name, product code, and test certificates.
