Import Flanges — Buy in Bulk from Supplier in China

The flanges from Shanxi Xinchang Minmetals Forging & Casting Flanges Co., Ltd. are manufactured using forging and casting processes for industrial piping systems. Available in carbon steel, stainless steel, and alloy steel variants, they conform to ASME B16.5 and DIN 2573 standards for pressure ratings up to Class 2500. Flange types include weld neck, slip-on, blind, and socket weld, each designed for specific stress and alignment requirements.

Forged flanges are preferred for high-pressure applications due to superior grain structure and impact resistance. Casting is used for larger, low-pressure units where cost efficiency is prioritized. Material composition follows ASTM A105 for carbon steel and ASTM A182 for stainless steel, with typical carbon content under 0.3% and manganese under 0.6%. Surface roughness is controlled to 125 Ra or better for sealing surfaces.

These flanges are sourced by engineering firms in oil and gas, water treatment, and heavy machinery sectors for pipeline junctions and equipment connections. Buyers typically order in quantities of 100 to 1,000 units, packed in wooden crates with steel strapping. Trade terms are commonly FOB Qingdao or CIF port of destination, with lead times of 30 to 45 days. Custom material grades and pressure classes require engineering review and tooling confirmation.
