ASME B16.36 class 300 slip on orifice flange

2024-09-27 10:54:04 Hits:45 American Standards / Product Standards

The ASME B16.36 class 300 slip-on orifice flange is a specialized type of flange used in piping systems where accurate flow measurement is required. It is designed to be used with an orifice plate, which creates a pressure drop that is measured to calculate the flow rate of fluids (gases or liquids) within the pipeline. This type of flange is part of the ASME B16.36 standard, which covers orifice flanges and their dimensions, pressure ratings, and applications.

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 slip-on 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.
(5)Threaded flanges are furnished in NPS 1 to NPS 8 only.

The ASME B16.36 Class 300 slip-on orifice flange is a key component for flow measurement systems in industrial applications. It provides a simpler, more cost-effective installation than a welding neck flange while ensuring accurate flow measurement when used with an orifice plate. Commonly used in industries such as oil and gas, petrochemical, and water treatment, this flange is designed to withstand moderate pressures and is part of a standardized system for ensuring flow accuracy across a wide range of applications.
