Fired Heater tube support

[Jvillar]

Hello everybody,

This is my first post, so hello to you all!

I am working in a new refinery project in which our licensor specifies "J" type hook tube supports for the fired heater tube. However, it does not specify or has a typical drawing of the tube support.

The specification says: "radiant top supports for vertical cylindrical heater shall be "j" hook type

Does anyone know of any standard which may define this type of support?

Furnace shall be designed according to API 560.

Thanks
Juan

HH 30 or 40 castings ( 309 SS) used to be the standard.
