What is a Class 600 Blind Flange

Compared to the cast iron flanges, forged steel flanges have better performance and adaptation in high pressure and temperature environment, the main difference between them is their manufacturing process, forge and cast. By the different ways they are connected to the main pipeline, there are mainly six types of flanges, blind(BL), socket weld(SW), threaded(THD), weld neck(WN),slip on(SO) and lap ring joint(LPJ).

In ASME B16.5 standard, there are several different schedule for the pressure environment the flanges should be applied to, called pressure rating, they are class 150 / 300 /400 /600 /900 /1500 /2500.

Let's conclusion, in description class 600 blind flange, Blind is the flange type, class600 is the pressure rating of the flange.

More Information We Need to Make Sure the Flange

Is it enough for us to manufacture a flange by description “class 600 blind flange”? Of course not.

Usually we need several main factors to totally make sure a flange material, flange type, size, pressure rating (if in WN flange, we still need the thickness of the pipes),the sealing face type, and of course material which has the most influence one on price.

American Manufacturing Standard of forged steel flanges

We can usually see ASME B 16.5 in a flange's description, which is the main standard for all forges steel flanges, but at some time we will also see ASME B 16.48 or ASME B 16.47 A/B, what are they?

ASME B 16.48 is the standard for a special kind of flange, they will be taken as fittings some times, which are spectacle blind, spade and spacer.

ASME B 16.47 A/B is the standard for flanges whose size is larger than 24 inches , there are two main series A and B in the standard, which is different by their usage in pipeline or valves. On thing you need to notice is this standard only cover blind flange and weld neck flange, if there are other types of flange bigger than 24 inches, we will need a drawing to manufacture it.

Sealing Face for Blind Flange

garlock-flat-face-raised-face-blind-flanges


There are three types sealing face for blind flange as below:

The raised face (RF) is the most common type of flange facing used. It is called a raised face flange because it has a raised surface above the bolting circle where the gasket is placed. These flanges are widely used in oil and gas pipelines.

Flat face (FF) flanges are similar to the RF flanges, but they do not have the raised area like the RF flange. Instead, the whole surface is flat.

A Ring type joint flange(RTJ) is a machined metallic ring with a deep groove cut into its face. This groove rests a metal ring which gets compressed when the connecting bolts of the flange are tightened.

What is Class 600 Blind Flange Used

A blind flange is a solid disk used to block off a pipeline or to create a stop. Similar to a regular flange, a blind flange has mounting holes around the perimeter and the gasket sealing rings are machined into the mating surface. The difference is that a blind flange has no opening for fluids to pass through.
