304 Stainless Steel BSP Threaded Flange, BS & EN Standard G Parallel Thread Weld-Free Flange for Overseas Export

304 stainless steel BSP/G imperial threaded flange is manufactured strictly according to BS1387 British standard and EN European standard. Different from NPT taper thread, it adopts BSPP parallel pipe thread structure, serving as a core weld-free fitting for British and European pipe systems in Europe, Middle East, Southeast Asia and Australia, solving common export problems such as thread incompatibility, docking misalignment and sealing failure between metric and imperial standards. Integrally forged from solid 304 stainless steel billets, the product features dense and stable structure without pores, sand holes or interlayers, with superior mechanical strength and pressure stability to ordinary plate-machined flanges. Precisely CNC machined BSP parallel thread delivers regular tooth profile, uniform pitch and smooth fitting without jamming or damaged teeth, achieving tight static sealing with standard gaskets for normal-temperature low-pressure general fluid conditions. Welding-free installation simplifies construction, disassembly and maintenance without open-fire equipment, ideal for overseas projects with limited construction conditions and fire prohibition. 304 steel provides excellent rust resistance, oxidation resistance and atmospheric corrosion resistance for long-term transmission of clean water, compressed air and common oil media, suitable for overseas civil buildings, light industry and general industrial pipelines. All outer diameter, thickness, bolt spacing and sealing surface dimensions fully comply with British and European tolerance standards for 100% interchangeability with overseas imperial valves and equipment without on-site secondary modification. All products are finely deburred, acid-passivated and surface-finished for export-grade appearance without tool marks and oxide spots, ready for direct export. Widely used in European building water supply, European HVAC systems, Middle East and Southeast Asia overseas pipe networks, foreign mechanical fluid pipelines and light industrial fluid transmission. We mass produce BSP, G and NPT multi-standard threaded flanges with complete imperial sizes and sufficient stock for global export, supporting customized export packaging and documents.
