321 Stainless Steel Flange ASME B16.5 Loose Flange American Standard High-Temperature Pipeline Conne

The 321 stainless steel loose flange complies with ASME B16.5, a core American standard for pipeline connection components, engineered for high-temperature industrial applications. Crafted from 321 stainless steel—alloyed with titanium to resist intergranular corrosion—it excels in environments up to 800°C, making it ideal for petrochemical, power generation, and heat-treatment systems. Its loose design enables easy alignment during installation, accommodating minor pipeline misalignments without compromising sealing performance. Featuring precision-machined sealing surfaces and robust structural integrity, this flange ensures leak-free connections under extreme thermal stress and pressure. Certified to ASME B16.5 dimensional and performance criteria, it guarantees universal compatibility with standard pipeline systems, delivering reliable long-term operation in harsh high-temperature conditions.
