Blind Flanges – MS, SS, PP, HDPE, PPRC & PVC
Product Description Blind Flanges and compatible end-closure flange solutions for industrial piping systems. Available in Mild Steel (MS), Stainless Steel (SS), Polypropylene (PP), High-Density Polyethylene (HDPE), Polypropylene Random Copolymer (PPRC) and Polyvinyl Chloride (PVC), these products are designed to close pipe ends, seal unused pipeline connections and provide access for inspection and maintenance. Blind flanges are commonly installed at the ends of pipelines, on valves, pumps, tanks and pressure-containing equipment where a secure closure is required. Depending on the material and design, they are available in metallic blind-flange configurations and compatible plastic flange-adapter assemblies. flange solutions to suit different industrial requirements, with material, dimensions, drilling patterns and pressure ratings selected according to the application and applicable standards.
