Shangdian Flange produces flat and dished end caps designed to close off the ends of piping systems. These end caps are fabricated from high-grade stainless steel to withstand internal pressure and prevent leakage, corrosion, or contamination. Available in a wide range of diameters and wall thicknesses, our caps comply with GB/T 12459 and ASME B16.9 standards. They are commonly used in pressure vessels, sanitary pipelines, and fluid transport systems where terminal sealing is required.
