Manufacturers of B16.47 Reducing flange, Stainless Steel Reducing flange

ASME B16.5 Reducing flanges are made of different materials depending on the application requirements. RC Metal Corporation is one of the leading manufacturers and suppliers of B16.47 Reducing Flanges and B16.5 Reducing Flanges among others. The Reducer Pipe Flange is used to reduce the diameter of the pipe at the point of connection. A flange is basically a circular object with a flange or washer on it for screwing and welding. Such items as Stainless Steel damper flanges are useful in pressure applications where the joint of two pipes must be absolutely tight. Flange reductions are important because they reduce pipe diameters and help maintain fluid pressure and flow in applications.

Do you know What is Reducing Flange?

ASME B16.5 approved Reduce flange design and construction. Reducing flange is used to reduce the diameter of the pipe. The Reducing flange joint consists of a reducing flange and a Standard Flange, which acts as a reducing coupling. As shown in Figure 1, the larger end of reducing flange A, in contact with standard flange B, is called the "dimension from which the reduction is made"; the smaller end of the reduction flange A, which will be Welded Pipe, is known as the "dimension to which the reduction is carried out". The stream should go from smallest to largest size. If the direction of the flow is reversed, serious turbulence can develop.

As shown in Figure 1, Reducing flanges are usually composed of 3 parts: i - flange, ii - flange thickness, iii - flange hub. Its characteristics are obvious: the face size, thickness, bolt size and outside diameter of the reduced flange are the same as those of the standard flange of the size from which the reduction is made. The size of the hub as well as the hole diameter of the reduction flange is usually the same as that of a standard flange of the size in which the reduction is made.

Why use a reducing flange?

In order to fabricate a pipe Reducer stainless steel Lap with two standard weld neck flange, an additional reducer as shown in Figure-2 must be used. The total length of this configuration is 2L+H, much longer than the L+M of a reduced flange joint, as shown in Figure-1. This means that using a reduced flange can effectively save space in a crowded situation. In fact, reducing flanges are most commonly used Fittings in installations where space is limited.

Types of Reducing Flanges

Reducer flanges manufactured according to ASME B16.5 are available in grades 150 to 2500. The surface of the reducer flange shall be the same as that of a standard matching flange. Generally, four types of reducer flanges are available as standard: reducer weld neck flange, reduce Slip on Flange, reduce threaded flange and reduce socket weld flange

  • Type 1 Reducing flange: if the bore reduction is fairly minor, the bolt holes must be spaced on / off centers so that they do not collide.
  • Type 2 Reducing flange: When the reduction is not significant and the perimeter of the smaller bore mating flange would impinge on the nuts, these flanges with threaded bolt holes are used
  • Type 3 Reducing flange: flanges with through holes for big bore bolts that are utilized where bores are significantly reduced.
Reduced neck flanges shall be supplied with a shaft and the dimensions of the shaft shall be the same as those of a Standard Flange of the size in which the reduction is made. Threaded, slide or slide Reducer Flanges can be supplied with or without a shaft. The size of the shaft shall be at least as large as the size of the standard flange of the size at which the reduction is made. The center can be larger or omitted as shown in the table below.

Key features and aspects of reducing flanges include:

Size Transition:

Reducing flanges have two different bore sizes on either side, allowing for the connection of pipes with varying diameters. The larger bore accommodates the larger pipe, while the smaller bore is designed to match the diameter of the smaller pipe.


Like other flanges, reducing flanges are available in various materials, including carbon steel, stainless steel, alloy steel, and other materials suitable for the specific requirements of the application. The material chosen depends on factors such as the type of fluid or gas being conveyed and environmental conditions.

Pressure Ratings

Reducing flanges are designed to withstand different pressure ratings based on the specifications of the piping system. It is crucial to select a reducing flange with the appropriate pressure class to ensure the integrity and safety of the overall system.


Reducing flanges are installed in the same manner as standard flanges. They are typically welded or bolted to the pipes, creating a secure and leak-free connection. Proper alignment and welding procedures are essential to ensure the reliability of the joint.


Reducing flanges find application in various industries, including petrochemical, oil and gas, chemical processing, water treatment, and more. Wherever a change in pipe diameter is required within a piping system, reducing flanges provide an efficient and reliable solution.


Reducing flanges are manufactured in compliance with industry standards such as ASME/ANSI, DIN, JIS, and others. Adhering to these standards ensures that the flanges meet the necessary quality and performance requirements.

Reducing flanges play a crucial role in piping systems by facilitating the connection of pipes with different diameters. Their design allows for a smooth transition, minimizing disruptions in fluid or gas flow and ensuring the overall efficiency and integrity of the piping network.

Advantages of Reducing Flanges

  • Reducing flanges come in several types including weld neck, slip-on and threaded
  • Reducing flanges are ideal for applications that require the fitting together of different sized pipes
  • manufactures reducing flanges to your specifications
  • Reducing flanges are the most economical way to mate pipes of differing sizes
