Referance Standard and Grade:
ASTM A105: Standard forged carbon steel pipe components for environmental and high temperature / high pressure systems.
ASTM A182: The standard for alloy and stainless threaded flanges.
Common alloy grades: F5, F9, F11, F22, F91; Stainless steel grades: F304, 304/, F316, F316L.
Although threaded pipe flanges come in different sizes, threaded pipe fittings are mostly used for small-diameter pipes. (Normally less than 4 inches)
On the other hand, it is not compatible with thin-walled pipe systems because there is no room for threading.
Types:
1. One seals the two pipe ends with a certain sealing surface and a lens pad. This type is mostly used for ammonia production but has been used less recently, and the lens pad has been replaced by a metal ring.
2. The other is the same as a normal flange and is sealed with two flange sealing faces.
Standard: ASTM A105, ASTM A182
Material: Carbon Steel, Stainless Steel, Alloy Steel
Size Range: 1/2'', 1'', 2'', 3'', 4'' to 24''
Pressure Class: Class 150 to 2500
Face: Raised face (RF), Ring type joint (RTJ)
