They are essential for chemical pipe fittings, as well as installing different types of flanges. A standard of these blinds is ASTM B182 and ASTM SB 182, which vary in size from 12″ 15″ NB to 48″ 1200″ NB. Dimensions vary according to the client’s requirements. These blinds are finished with various heat treatment processes to eliminate structural defects, ensuring the blinds offer an excellent finish without leakage.

ASME SA 516 GR 70 Spectacle Blind Flanges are processed with high-quality raw materials, improved machinery, and advanced methods to produce superior-quality spectacle blinds with high precision and excellent surface finishes.

This category of blind people is best suited to complicated pipe fittings or other operations that require guidance from an expert; you can use these to increase the lifespan of your fittings.

Two pipe flanges are fond of with a straightforward safety measure to form a spectacle blind. This blind consists of two pipe flanges joined together with a spacer to enable uninterrupted flow when used. Must rotate the blind end between the two flanges until it is blocked. As it replaces a standard blind flange, the spectacle blind flange prevents leaks when sealing pipe connections.
