Rolling Diaphragm Fabric Reinforcement
Fabrics
A
key component of rolling diaphragms is the fabric reinforcement
selected to ensure the diaphragm will withstand the application
pressure and cycle life expectations. DiaCom has developed
a comprehensive selection of standard fabric styles, each
with specific physical characteristics, that are selected
based on weave patterns, tensile strength, formability and
chemical and heat resistance capabilities, as well as other
variables. DiaCom technical personnel are available
to assist in selecting the proper fabric for a specific application.
