At Goodrich Gasket, we manufacture Non-metallic flat
gaskets from arimid fiber, glass fiber, elastomer,
Teflon (PTFE), graphite etc. according to ASME B16.21
which covers types, sizes, materials, dimensions,
dimensional tolerances, and markings for non-metallic
flat gaskets.
At Goodrich Gasket the following information shall be
included in markings: manufacturer’s name or trade mark
or material designation. Gaskets shall be packaged with
NPS, class, gasket manufacturer’s name, material
designation, thickness and ASME B16.21 marked or tagged
on the package or the gasket. At the option of the
manufacturer the DN designation may be included.
NPS followed by a dimensionless number is the designation
for nominal pipe size as described in ASME B36.10M and
is related to the reference nominal diameter DN used in
international standards. Class followed by a
dimensionless number is the designation for common
flange pressure-temperature ratings as given by the
referenced flange standards.
At Goodrich Gasket, non metallic flat gaskets are made of
resilient or pliable materials and metal or non metal
composites are incorporated as reinforcement or filler
material. The material selected shall be compatible with
the fluid and suitable for the pressure-temperature
conditions of the service.
Selection of a flat gasket material and gasket thickness
suitable for given service application is the
responsibility of the user subject to the requirements
of any applicable code or government regulation and also
by considering the properties of the flat gasket
material as well as the intended service application.
