ASME B16.5 ASTM A182 F51 RF 300LB 10 Inch Orifice Flange ASTM A182 F51 RF 300LB 10 Inch Orifice 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.

An orifice flange is a type of flange that is specifically designed for use in orifice measurement applications. It consists of two flanges, with an orifice plate placed between them. The orifice plate has a hole in the center, which allows for the measurement of fluid flow rate, pressure, or other parameters.

Orifice flanges are commonly used in pipelines for measuring flow rates of gases, liquids, or steam. They are particularly useful in applications where accurate flow measurements are required, such as in industrial processes, oil and gas industries, power plants, and water treatment facilities.

The orifice plate in the flange helps create a differential pressure across the plate, which is proportional to the flow rate. This differential pressure can then be used to calculate the flow rate using the Bernoulli's equation or other flow measurement standards.

Orifice flanges come in various sizes, shapes, and materials to suit different application requirements. They are typically manufactured following industry standards such as ASME B16.36 or API 6A.

Overall, orifice flanges provide a reliable and cost-effective solution for flow measurement in various industries.
