What flanges are wound gaskets with an inner ring used for?
Thread Content
What type of flanges are winding gaskets with inner rings mainly used for? And what flanges are used with the in-line and out-line winding gaskets? Could an expert please explain? Sometimes I can’t tell the difference. Thank you. Bonus points
Generally, gasket wraps consist of inner and outer rings; raised and recessed flanges can only use inner-ring gasket wraps.
Why can only gasketing with an inner ring be used for male and female flanges? I don’t understand. Please explain it. Thank you

For your question, it is recommended that you select the materials in accordance with the provisions of 7.4.4 in the \"SHT 3059-2012 Specifications for the Selection of Materials for Petrochemical Piping Systems\". For your reference
Winding gaskets with an inner ring are mainly used for sealing on flat flanges. Intra- and extraluminal gaskets are used for sealing on uneven surfaces.
Flanges with internal reinforcement rings for concave-convex flanges; flanges with internal and external reinforcement rings for convex flanges. By looking at how concave-convex flanges are designed, it becomes clear why external reinforcement rings cannot be used – there is no space for such rings
I instantly feel like you’re new; good luck, newcomer.
That’s not right to say; isn’t this just a place for communication?
The basic version can also be used for uneven surfaces; however, pads with inner and outer rings are not suitable for use on uneven surfaces due to their relatively large outer diameter
Those with an outer ring are used for male and female flanges; the outer ring occupies sealing space, which can lead to insufficient sealing area and subsequent leakage
