Flow Correction

When customers have a challenge with a particularly abrasive product or a fast flowing product that enters at an angle, wear and tear on the flexible connector can be easily reduced by using a 'flow correction' technique.

 

There are three standard methods of achieving flow correction as outlined below:

  • Method 1: Larger diameter BFM® spigot vs pipe
    Suited to low-velocity/gravity-fed product flows.
  • Method 2: Flow ring extends inside connector
    Suited to low-velocity/gravity-fed product flow.
  • Method 3: Flow ring finishes before spigot cuff
    Ideal for high-velocity flow.

    Method 1: Larger diameter BFM® spigot vs pipe

    This method is particularly well suited to low-velocity or gravity-fed product flows.

    We keep the BFM® spigot diameter at the inlet larger than the diameter of the pipe feeding the product. This way, the product doesn't make contact with the walls of the connector as is it falls through.

    Method 2: Flow ring extends inside connector

    Suited to low-velocity or gravity-fed product flow.

    To ensure minimal product contact against the walls of your BFM® connector, insert a flow correction ring that extends past the cuff of the connector as shown in the illustration below.

    Important to note: you will need to ensure that the gap between the flow correction ring and the edge of the spigot cuff (dimension ‘A’ shown below) is big enough to allow for connector replacement.

    Method 3: Flow ring finishes before spigot cuff

    Ideal for high-velocity flow.

    Insert a flow-correction ring on the inside of the inlet BFM® spigot. Ensure that the ring ends before the spigot cuff. This will assist in directing the product flow inwards and away from the walls of your BFM® connector.

    This is suitable for any diameter spigot and doesn’t impact connector replacement.
