Are the slip flanges on enamel reactors all custom-made? Does the other half of the flange that pairs with the loop flange need to be custom-made?

Are the slip flanges on enamel reactors all custom-made? Does the other half of the flange that pairs with the loop flange need to be custom-made?
HG/T 2105-2011 Loop Flange for Laminated Glass Equipment
This standard does not specify the dimensions for the flanging of the connections on enamel reactors. How should the flanging be done? Do enamel kettle manufacturers purchase slip-on flanges or fabricate their own flanges? Why, when users use enamel-lined reactors, are the pipes connected to them not fitted with slip flanges anymore, but instead ordinary flanges?
It is not non-standard; it comes in two pressure grades: PN0.6 and PN1.0. It can be connected to HG/T20592-2009.
The loop flange is designed to meet the requirements of the glass lining process; it can certainly be made in the style of HG/T29592 flanges, but it must have transition arcs. Since it is not a glass-lined pipeline, there is no need to use a swivel flange design.
The equipment is all lined with glass lining; then why aren’t the external pipes lined with glass lining as well?
Is the transition arc on the flange sealing surface? Then those with transition arcs would become non-standard flanges, right?
I don’t understand what exactly you want to ask...
This is classified according to the pressure level
