Plate Flat Weld Steel Pipe Flange Aluminum Alloy 2A14 Type Spacer Pipeline Forged Plate Flange

Flange is the parts which connects two pipe ends, flange connection is defined by the flange, gasket and bolt three are connected as a group of combined sealing structure of the detachable connection.
The gasket is added between the two flanges and then fastened by bolts. Different pressure flange, thickness is different, and the bolts they use are different, when pump and valve connect with pipe, the parts of the equipment are also made of the corresponding flange shape, also known as flange connection, usually closured bolted connection parts are also known as flanges, such as the connection of ventilation pipe, this kind of parts can be called "flange type part", but this connection is only part of a device, such as the connection between flange and water pump, it's not inapposite to call water pump as flange type parts,but relative small valve, it can be called as flange type parts.
blind flanges

A blind flange is a solid, round plate used to cover or close off the end of a pipe, valve, or vessel. It is commonly used in piping systems where a temporary or permanent closure is required. Blind flanges do not have an opening or a bore and are typically bolted onto the end of the pipe or fitting using bolts or studs. They are mainly used for isolation purposes, maintenance, or to prevent the flow of fluids or gases.

2A14 is a kind of aluminum and aluminum alloy squeezing rod. Because the amount of copper is high, the intensity is high and the thermal strength is better.
