Specifications

AS 2129 T/E 316L Bossed Flange Flat Face
1. Material: 316L
2. Size: 2" (DN50)
3. Standard:  AS 2129

4. Type: Table E

Slip-on bossed flanges are designed to slip over the pipe and are machined with the inside diameter of the pipe flange slightly larger than the outside diameter of the pipe.

These allow the flange to slide over the pipe and are joined to the pipe with a fillet weld at the top and the bottom of the flange.

A bossed type has a reinforcing disc around the outside of the pipe which helps support the pipe making for a stronger joint.

In Australia the BS and AS flange standards are essentially the same but have been metricated. Consequently metric sizes are stated as ‘DN’ (Nominal Diameter) in mm. Equivalent imperial sizing is rounded to the nearest multiple of 25mm (for 2” and over) as below. However the actual dimensions and bore sizes have not changed. ‘NB’ (Nominal Bore) is also sometimes used when referring to valve sizes.

AS2129 originates from BS10 and has been metricated. In some cases slightly larger bolt holes provide better clearance as metric bolts are specified in lieu of UNC bolts used by BS10. AS4087 is an update of AS2129, however AS2129 is still widely used so it has not been deleted as a standard, however, it now only covers AS table D, E to H.

Uses of threaded bossed flanges:

Threaded bossed flanges are threaded in the bore which match an external thread on the pipe. Threaded bossed flanges are used with pipes that have external threads. The benefit of these flanges is that it can be attached without welding.

Threaded bossed flanges can be fitted to pipes of various sizes without welding and this is one chief benefit for which these flanges are highly demanded.

  • They can be used in extremely high pressure applications, particularly at or near atmospheric temperature, where the necessary post weld heat treatment is not possible.
  • They are ideal for small diameter piping applications.
  • They are economical and time saving devices.
  • These threaded bossed flanges are normally designed for non-cyclic applications.
  • The flanges are suitable to be used in applications where welding is hazardous.
  • They can be used in highly explosive areas.
