NORTHBOROUGH, Mass., Feb. 6 /PRNewswire/ -- Aspen Aerogels'
Spaceloft(R) and Pyrogel(R) insulation materials easily meet 20- to 35-year
performance requirements for high pressure, high temperature subsea
pipe-in-pipe applications in the Gulf of Mexico and other areas, according
to a new study.
The study, conducted for a major engineering company and oil company,
evaluated Spaceloft's and Pyrogel's thermal conductivity, compression,
water repellency and long-term shrinkage before and after aging. The
testing determined that both materials are highly suitable for long life in
the high pressure and temperatures (up to 350 degrees F) of ultra deep
water pipe-in- pipe lines.
"Aspen Aerogels' materials are delivering performance where the benefit
is high to the user. Our customers' requirements are changing as they go
deeper, and we are happy to deliver a solution to their stringent
insulation needs," said Harry Walkoff, Aspen Aerogels' vice president of
sales and marketing, Hydrocarbon Processing Industries.
In pipe-in-pipe lines, Aspen's insulation is used between the inner and
outer pipe, offering the lowest thermal conductivity while being much
thinner than other pipe insulations. This means the outer pipe can be
smaller, saving substantially on steel weight and cost. Spaceloft and
Pyrogel come in reinforced, flexible blanket form, which greatly simplifies
Aspen's pipe-in-pipe insulation has been proven in projects in Gulf of
Mexico, North Sea and West Africa and will soon be used in offshore Brazil.
With future drilling expected to be in deeper waters, the ability of pipe
insulation to withstand high fluid temperatures is vital.
-- Thermal conductivity -- Both materials reported minimal thermal
conductivity change after aging -- a mean variation within 3 percent.
-- Compression -- The materials showed acceptable strain recovery and
thermal conductivity after being exposed to simulated loading and
-- Water repellency -- Hhydrophobic properties of the materials were
unaffected after ageing.
-- Long-term shrinkage -- Testing showed no gap formation after simulated
installation and mechanical fastening of the insulation system on the
