304 Stainless Steel Threaded Flange , Thread European Standard Weld-Free Pipe Flange

—

This 304 stainless steel BSP/G imperial threaded flange is manufactured strictly according to BS1387 and EN European standards. Different from NPT taper thread, it adopts BSPP parallel pipe thread, perfectly compatible with British and European pipe systems, serving as a core welding-free fitting for overseas projects. Forged from solid 304 stainless steel billets, the product features stable structure without pores or sand holes, better mechanical performance than plate-machined flanges. Standard BSP parallel thread ensures smooth installation and accurate fitting with perfect gasket tightness for normal-temperature low-pressure fluid conditions. Welding-free installation enables fast assembly and easy maintenance, ideal for overseas construction sites with welding restrictions. 304 steel provides excellent rust and oxidation resistance for water, air and common oil media. All outer diameter, thickness and bolt spacing fully comply with European and British standards for 100% interchangeability with overseas valves and equipment. Deburred and acid-passivated surface ensures clean appearance and good anti-corrosion performance for direct export. Widely used in overseas water supply, European HVAC, mechanical pipelines and light industrial projects. We mass produce BSP, G and NPT threaded flanges with complete imperial sizes and sufficient stock for export orders.
