How Fitting Pressure And Thread Rating Are Determined?

Stainless Steel Fitting Pipe Pressure Rating

Pressure rating of AFK ferrule joint

The end of AFK ferrule joint has reached the working pressure level offerrule listed in AFK ferrule data. In order to install a safe leak proofsystem, it is critical to carefully select high-quality ferrules.

Basis For Pressure Aatings At Threaded Ends Pipe Fittings (NPT and ISO7)

For the case of both ferrule joint and pipe thread end, the pressure ratingis determined by the end with lower pressure rating. The taper end pressures formale and female threads are listed in the table. If the external thread andinternal thread of the same nominal size have the same pressure rating, theinternal thread often needs a thicker pipe wall, which may cause the joint to betoo large and heavy to use.
