A high pressure, high temperature
combination of natural gas, carbon dioxide and hydrogen sulfide is a harsh
environment for any seal. However, Seals Easterns contribution of advanced technical
papers and patents have tackled the problems. Consequently, we are a major supplier of
high pressure seals
and packer elements in the energy industry.
Seals Eastern was the sole-source for all fuel and
oxidizer seals in the "Lance" missile
system. Fluoro-silicone and phenyl-silicone rubber were bonded to large aluminum retainers. Extensive
studies on cross-linking, bonding technology, and surface chemistry
resulted in the production of a successful missile system.
A low warranty cost engine requires seals able to resist
stress-relaxation. Seals Eastern supplies millions of low
compression-set seals that ensure leak-free service in heavy-duty diesel engine applications. These
seals have outstanding performance long-term performance in the presence of
traditional coolants and the Organic Acid Technology ("OAT")
coolants. These seals also withstand modern engine oils that have been
formulated to withstand higher operating temperatures.
A rapid decrease in pressure for seals in high-pressure
applications can be a recipe for failure. In fact,
a predictable swelling response in high-pressure gases such as methane,
carbon dioxide, and hydrogen sulfide. The destructive consequences of
this swelling is not so much during the absorption but when the system pressure is suddenly relieved. In the phenomena of explosive decompression
("ED"), the gas absorbed by the polymer expands rapidly, as
described by Boyles law, upon the
release of system pressure. The consequences to a seal are catastrophic.
Such failure can occur in gas compressors, down-hole applications, and
other situations where high pressure is commonly encountered. Since the
1980s, Seals Eastern has supplied explosive decompression resistant seals to major
manufacturers of turbines, compressors, gas re-injection equipment, pumps, and other fabricators who
must mitigate the effects of high-pressure gases in their equipment.
Seals Eastern is dedicated to providing engineered sealing products using high quality polymer compounds.
We continually strive to meet statutory and regulatory requirements, customer specifications, and delivery
requirements by involving each and every employee at all levels. We continually strive to improve the
effectiveness of our QM Systems and the Company's operations by utilizing teamwork and statistical
measurements of performance.
Seals Eastern Manufacturing Inc. pledges to implement and operate the ISO-14001 Environmental Management System to further enhance environmental performance. Our main objectives and commitments are to:
• Conduct operation in a responsible manner free from recognized hazards.
• Comply with applicable environmental, safety, and health laws and regulations and make records of performance available to the public.
• Respect the safety, environmental concerns, and health of our employees, customers, suppliers, and community neighbors.
