Soft Iron 347SS Octagonal Ring Joint Gasket Lens Ring Flange

Soft Iron 347SS Octagonal Ring Joint Gasket Lens Ring Flange
ASME B16.20 347SS Octagonal Ring Joint Gasket
Operating range
The pressure and temperature depend on the combination of materials used.

Chemical resistance:The corrosion resistance depends on the selected ring
material.

Materials
RTJ gaskets are available as standard in soft metal and in 304, 316 and
stainless steels. Versions in other materials on request.



Style R ring type joints are manufactured on oval (2962/R) and octagonal
profiles (2961/R).
Both styles are interchangeable in the modern flat bottomed groove.
Octagonal profile joints are interchangeable on flat bottomes groove flanges
which have a 23 degree angle groove wall

Advantages
Metal-to-metal contact creates a reliable seal
Suitable for extreme pressure and temperature requirements
Certified quality (including surface hardness)
we supplies ring joint gaskets (RTJ Gasket) with the hardness numbers as
follows:

We specializes in ring joint gasket, including ring gasket in R, RX, BX, IX
types, lens gasket, weld ring gasket and bonnet gasket(according to client's
drawing). The metal gasket designed for use in high pressure, high
temperature application necessitated the need for a high integrity seal. Our
products are widely used in flat gate valve, Christmas tree, pipeline
fittings, flange, high pressure vessel, oil &gas industry, wellhead
assembly, petrochemical industry and the like.
We can offer more than 30 kinds of materials, such as 321SS, 347SS, 316SS,
304SS, Inconel 625, Monel 400, INCOLY 825, Nickel 200, Duplex F44, soft
iron, low carbon steel and so on. We could produce the maximum outside
diameter is 2500mm. We have over 10 years experience in export business. Our
products are sold to Southeast Asia, Middle East, Europe and America and
well appreciated by our clients.

Programming interface ring Joint gaskets come in two fundamental sorts, an
oval cross segment and an octagonal cross segment. These essential shapes
are utilized in pressures up to 10,000 Rubber Seals and Gasket. The
measurements are institutionalized and require uniquely notched spines. The
octagonal cross segment has a higher fixing proficiency than the oval and
would be the favored gasket. Be that as it may, just the oval cross segment
can be utilized in the old sort round base notch. The more up to date level
base furrow configuration will acknowledge either the oval or the octagonal
cross segment. The fixing surfaces on the ring joint sections must be easily
completed to 63 smaller scale inches and to be liberated from shocking
edges, apparatus or babble marks. They seal by an underlying line contact or
an edging activity as the compressive powers are applied.
