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.

10:What industries does Shangdian Flange accept orders from?
—Flanges and pipe fittings serve as core connecting components for industrial piping systems, widely applied in chemical engineering, pressure vessel equipment, pharmaceutical clean pipelines, high-purity semiconductor pipelines, liquid cooling systems for data centers, LNG (liquefied natural gas), nuclear power, marine & offshore engineering, power station boilers, metallurgy, water treatment, papermaking and many other sectors.
Shangdian Flange focuses on two core product lines. The first is heavy-duty industrial flanges and pipe fittings designed for working conditions requiring high tensile strength, high temperature & high pressure resistance and outstanding anti-corrosion performance. The second category covers sanitary clean flanges and pipe fittings, tailored for scenarios with strict precision and high cleanliness standards.
We excel at customized production for extreme service conditions, including highly corrosive media in chemical plants, pharmaceutical sanitary pipelines, high-purity semiconductor systems, liquid cooling systems for data centers and energy storage equipment. We boast mature manufacturing experience covering nickel-based alloys, Hastelloy alloys, super duplex stainless steel and other specialty materials.
