This material standard also confirms for the material to be an ideal use case in low to high pressure and temperature conditions. This is because of their ability to show good leak resisting performance, when used for connection purposes. Most importantly, the tapered hub ensured for the uniform distribution of pressure forces, for accurate fluid or gas flow rates.

On the contrary, many use cases reveal for the usability for BS3293 150 LB weld neck flange. When deciding for the shells, which needs flanging, it requires two important things:

  • Firstly, the OD must be equal to the pipe size.
  • Second, it is equally important for maintaining flange design.

Another observation comes from their use case, where they offer excellent corrosion resistance. Adding to this, they even show good durability and strength, because of their leak proof performance. But there is one disadvantage of using it, and it comes from the cost factor.
