1. Stainless Steel SS310S Introduction
Type 310S is a high temperature chromium nickel austenitic stainless steel with high creep strength that resists oxidation at temperatures up to 2000˚F in dry air. Type 310S forms a tenacious scale at high temperature and is resistant to spalling and performs better than Type 309 in thermal cycling applications. Type 310 has good sulfidation resistance and good resistance to carburization in moderately carburizing atmospheres. Type 310S is the low carbon version of Type 310 and is utilized for ease of fabrication due to its better formability and weldability. Type 310S is non-magnetic in the annealed and cold worked conditions and is as resistant to corrosion as Type 304/304L.

3. What is the difference between a RTJ, FF, and RF flange on seals
and thermowells?
The raised face, RF, is the standard process connection on our
third party seals and thermowells. Both have options for a RTJ and
FF type flange connections. The Raised Face (RF) is the most common
type used in process plant applications.
The gasket surface of the flange is raised above the bolting circle
face. A Ring-type Joint (RTJ) can also have a raised gasket face
with the difference being the ring groove machined in this face.
This groove will accommodate a steel ring gasket for flange mating.
The Flat Face, FF, flange has a gasket surface that is in the same
plane as the bolting circle face.
None of these three flange types are interchangeable between types,
i.e. RTJ flange cannot be mated to a RF flange.
