Graphite
seal is simple device made from graphite. It is used to fill the vacant spaces between the coupling surfaces to avoid leakage
& wastage of gas and fluids. It helps in maintaining pressure and avoids
contamination from an external environmental condition. As the graphite can endure
pressure, heat and aggressive chemicals, the graphite seals are useful in refineries,
industrial fluid sealing, and steam services.
According to study, “Global Graphite Seals Market Status (2015-2019) and
Forecast (2020-2024) by Region, Product Type & End-Use”
the key companies operating in the global graphite seals market are GrafTech,
EagleBurgmann, Lamons, Guangan Chemical, Mersen, Teamful Sealing Technology,
Flexitallic, Graphite Tech, Gee Graphite, Tiansheng, Mercer Gasket, Hennig
Gasket, Nippon Valqua, SinoSeal, Wealson, Qimeng, Shuk. The key industry
participants are developing & testing graphite seals with composite
material designs to increase the functionality of the product in harsh
conditions in heat transfer and chemical processing applications. In addition,
several players are also developing patented materials for improving the
features of sealing components, thus driving the demand for graphite seals.
Based on type, graphite seals market is
segmented into flexible graphite seals and inflexible graphite seals. Flexible
graphite seals are made with high purity flexible graphite reinforced using
metallic or non-metallic inserts.
Based on product type, market is segmented
into mechanical seal, rotary seal, O-ring seal and other seals. Based on
application, market is segmented into steam generator, pressurizer, heat
exchanger, shut off valves, quarter rotation, adjustment & regulation in
linear movement, piping shutters, piping connecting flange & boiler
devices, device closings with autoclave systems, rotating machinery (interior
of pumps and compressors), valves (body/bonnet sealing, seat sealing),
cryogenic applications, hot air and other gas circuit. In addition, based on
end-use industry, market is segmented into oil & gas, marine & rail,
automotive, electrical & electronics, power & energy, industrial &
manufacturing, chemical & petrochemicals and others.
The graphite
seals market is driven by increase in production of motor vehicle &
machinery output, followed by rise in improvements in seals, growth in capacity
to purchase gasket & seal containing equipment due to increasing fixed
investments. However, increase in automation leads to decline in usage of seals
and rise in prices of raw materials such as graphite may impact the market.
Moreover, rise in industrialization in developing economies and growth in
better transmission sealing to meet original equipment manufacturer (OEM)
demand are key opportunities for market. Furthermore, growth in usage of
industrial automation is a major challenge for market.
Based on geography, the Asian-Pacific region
holds major share in graphite seals market owing to growth in industrial sector and rise in disposable income in the
region. Whereas, the North-American and European regions are estimated to
witness higher growth rate due to rise in demand from the chemical &
petrochemical sectors over the forecast period. In upcoming years, it is predicted
that future of the market will be optimistic as a result of increase in product
demand from oil & gas industry during the forecast period.
