STYLE R
FOR USE WITH MALE & FEMALE AND TONGUE & GROOVE ASME B16.5 & BS 1560 FLANGES
Standard Style R gaskets embody
all the exclusive features of Flexitallic
design for keeping compression
values in balance with bolting and
providing adequate resilience
to compensate for variable stresses
encountered in service. Standard
Style R gaskets are manufactured
to a nominal thickness of .125"
(3.2mm). Optimum compression
is in the range of .090" to .100"
(2.3mm to 2.5mm) thick.
There are three types of Style R gaskets:
(a) Style R-1 indicates gaskets for use with large male and female flanges.*
(b) Style R-3 indicates gaskets for use with large tongue and groove flanges.
(c) Style R-4 indicates gaskets for use with small
tongue and groove flanges.
*As a general rule, the use of Flexitallic Spiral-Wound Gaskets with small
male and female flange facings is not recommended.
Dimensional limitations established by the proportions of the small tongue and
groove facings limit the possibility of increasing gasket dimensions to improve
the load carrying capacity in the higher pressure series. For this reason, it is
suggested that large tongue and groove facings be selected for new construction
when class 900, 1500 and 2500 flanges are to be used. Style R-4 gaskets
maybe compressed an additional amount when exposed to the higher bolt loads,
but not to the degree that the gasket will be crushed due to the radial support
provided by the confining groove.
Special Style R gaskets are adaptable to non-standard flanges and can be
designed and manufactured according to specifications for high and low pressure
applications and for severe corrosive conditions.
When ordering special Style R gaskets for non-standard flanges and for special
applications, furnish complete data on Flexitalllc Gasket Engineering Data Form.
