Flange
This flange is manufactured from carbon steel, stainless steel 304, or stainless steel 316 to meet international pressure and temperature demands in industrial piping systems. It is produced to ANSI, DIN, EN, ASTM, and BS standards, with pressure ratings ranging from PN6 to PN250. Available configurations include welding neck, slip-on, blind, and socket weld types, each designed for secure, leak-resistant connections in high-stress environments.
The carbon steel variants offer strength for general industrial use, while the stainless steel grades provide corrosion resistance in chemical and petrochemical applications. Standard material compositions follow ASTM A105 for carbon steel and ASTM A182 for stainless steel, with typical carbon content under 0.3% and chromium-nickel levels aligned with 304/316 specifications. Surface finish is mill-grade unless otherwise specified, with no coating applied unless requested by the buyer.
These flanges are used in oil and gas pipelines, chemical processing plants, and power generation facilities where pressure integrity is critical. Buyers include engineering contractors, maintenance suppliers, and OEMs sourcing for mid- to high-pressure systems. Packaging is standard export-grade with rust inhibitors and wooden crates. Trade terms are negotiable, with FOB and CIF options available. Lead time is typically 30 to 45 days after order confirmation, subject to material availability and quantity.

Sourcing Flange from Zhengzhou Huitong Pipe Fitting Co., Ltd - China Import Guide
Before ordering, verify the material grade certification against the specified standard, especially for stainless steel 304/316. Confirm that the flange dimensions match the piping system using ASME B16.5 or EN 1092-1 drawings. Request a material test report for each batch to validate chemical composition and mechanical properties. Do not rely on supplier claims without documentation.
Confirm the Incoterms with the supplier - FOB is common, but CIF may include additional insurance costs. Lead time typically ranges from 30 to 45 days depending on order volume and material stock. Payment terms are usually 30% advance with balance against copy of shipping documents. Ensure packaging includes rust inhibitors and is labeled with handling instructions for overseas transit.
Perform a pre-shipment inspection focusing on flange face flatness, bolt hole alignment, and surface defects. Use a surface roughness gauge and dial indicator for dimensional checks. Request a copy of the mill test certificate and ensure it includes heat number, tensile strength, and elongation values. Retain samples from each batch for future quality audits, especially in critical pipeline applications.
