Accurate Flow Measurement Robust Leak-Proof Seal Orifice Flange ASMEB16.5 Class150 1. Product Description An Orifice Flange is a specialized type of flange assembly used to measure the flow rate of liquids or gases in a pipeline. It consists of a pair of flanges, orifice plates, jacking screws, and tapping holes. The key component, the orifice plate, is a thin plate with a precise, concentric bore that is securely mounted between the two flanges. 2. Product Purpose The

Easy Installation Space Saving Insert Blind Flange ASMEB16.5 Class150 1.Product Description An Insert Blind Flange is a solid disc with no center hole, designed to be inserted and bolted between two standard flanges in a piping system . Its primary function is to block off sections of a pipeline . Unlike a pipe cap, a blind flange is secured with bolts, making it easy to install and remove for maintenance, inspection, or system modification . It serves as a reliable,

Isolation Zero Leakage Spade flange ASMEB16.5 DN80 Class150 1.Product Description A Spade Flange is a specific type of flow control and isolation device used in piping systems, typically employed in conjunction with a Spacer Flange or Ring.
