Blind Flange Definition:

A blind flange looks like a plate with bolts holes around. There is no inner hole on the blind flange comparing to other type of

flanges, so the blind flange is used to close the end of a vessel or piping system. Blind flange also be used for pressure test

for prevent the liquid or air flow

Blind flange is like a solid disk without whole in the middle, only with mounting holes (for connecting purposes) functioned to

block off the pipelines to stop the flows.

Sealing types

According to different pipeline pressure and seal gasket type, there are different sealing surface types for steel pipe flange.Fl-
at face (FF) pipe flangs It is suitable for less pressure occasion.( PN≤1.6MPa).

Raised face (RF) pipe flange

Sealing surface structure is simple and smooth, and easy for machining. Meanwhile it’s easy to carry out anti-corrosion lining.
However, the contact area is larger, the gasket will become squeeze on both sides easily as pre-loading. Then it will not easy

to press.

Male-female (M/F) face flange

It is composed of a convex and concave surface, placing the gasket on the concave. It can prevent the gasket from being ext-

ruded. So Male-female face flanges can be applied to the higher pressure occasions.

Tongue-groove (T/G) face steel flange

The touch surface is made of tongue and groove. The gasket is placed in the slot, and it cannot be squeezed.
Comparing RF and MFM, T/G face flange can obtain good sealing effect. The structure and manufacturing of flange are more

complex.It is difficult to replace the gasket in the slot. Tongue and groove seal face is suitable for flammable, explosive, toxic

medium and high pressure occasions.
