ASME B16.36 class 300 threaded orifice flange

2024-09-27 13:44:18 Hits:36 American Standards / Product Standards

The ASME B16.36 Class 300 threaded orifice flange is a specialized component designed to facilitate accurate flow measurement in piping systems. It is used alongside an orifice plate to measure the flow of liquids or gases through the pipeline by creating a pressure drop that is measured via pressure taps. This type of flange is part of the ASME B16.36 standard, which outlines the dimensions, materials, and testing requirements for orifice flanges.

ASME B16.36 class 300 threaded orifice flange dimensions:

The dimensions of ASME B16.36 class 300 threaded orifice flanges are consistent with other flanges in the ASME B16.5 standard. This ensures compatibility with other piping system components.

GENERAL NOTES:
(a)Dimensions are in inches.
(b)All other dimensions are in accordance with ASME B16.5.
NOTES:
(1)Other NPT sizes may be furnished if required.
(2)For threaded flanges,verify that TT drilling extends to inside diameter of pipe after assembly and is free from burrs.
(3)Bolt lengths include allowance for orifice and gasket thickness of 0.25 in.for NPS 1 to NPS 12 and 0.38 in.for NPS 14 to NPS 24.
(4)In conformance with ASME B16.5,stud bolt lengths do not include point heights.

ASME B16.36 class 300 threaded orifice flanges are widely used in industries where flow measurement is critical, such as:

    • Oil and gas
    • Chemical processing
    • Power generation
    • Water treatment

ASME B16.36 class 300 threaded orifice flanges are particularly suitable for lower-pressure applications or when welding is not feasible, such as in environments where heat may damage sensitive materials or equipment.

The ASME B16.36 class 300 threaded orifice flange is a key component for flow measurement systems that require threaded connections. It is used in conjunction with an orifice plate to measure the flow of gases and liquids in pipelines. These flanges are ideal for low to moderate pressure applications, particularly when welding is impractical. Threaded orifice flanges offer ease of installation and maintenance, making them a versatile choice in a variety of industries, including oil and gas, chemical processing, and water treatment.
