Annual Report 2011
Heat Pipes and Heat-Pipe Exchangers
The Heat Pipe is a thermal transfer device that transfers
heat quickly from one point to another. Heat Pipes, with
their excellent heat transfer capacities and rates, are used in
areas where heat is required to be transmitted immediately
and effectively with no heat loss. Our Heat Pipes can transfer
heat 3,000 times faster than the heat-transfer rate of a
copper pipe. A Heat-Pipe Exchanger consists of many Heat
Pipes bundled together. Sunpower led the development of
national standards for heat pipes and participated in drafting
the national standards for core & coreless heat pipes that
were eventually approved and promulgated in 2011.
Our Heat Pipes and Heat-Pipe Exchangers facilitate the
recovery of residual heat in petrochemical, steel and chemical
projects. They are also used to protect the permafrost
foundation in the construction of roads, railways and oil
pipelines. Examples in which our heat pipes have been used
in signifcant projects include: Qinghai-Tibet railway and the
Sino-Russia oil pipeline. Leveraging on the techniques of
producing heat pipes, the Group subsequently developed
its proprietary Waste-Heat Recovering Systems based on
its core heat-transfer technology which has successfully
secured domestic and international orders. These products
have also been successfully applied in a number of projects.
Pipe Supports
The main products of this segment are pipe supports and
temperature insulated materials.
Our patented products provide support to the pipelines by
isolating effects of ambient temperature and minimising
energy loss during transmission. To cater to the various
project requirements of our customers, we developed
several types of Pipe Supports with varying characteristics,
for example, the BL series of ultra low temperature cold
insulating Pipe Supports, the BR series of high effciency
heat insulating Pipe Supports, the JZ series of shock
absorbing Pipe Supports, as well as PIR series of cold
preservation pipe supports. Based on market demand,
we have also successfully enlarged our production lines
by providing our foam glass products to supply complete
cold prevention and shock absorption systems. Our Pipe
Supports products have penetrated into the international
markets and have been used to connect a variety of pipes
such as liquefed natural gas (LNG) pipes, ethylene storage,
steam pipes, pressure pipes etc.
Energy-Saving and Environmental Protection
Systems
Our Energy-Saving and Environmental Protection Systems
are used mainly for the waste treatment in petrochemical,
chemical and coal chemical industries (The wastes include
industrial waste water, waste gas & residue). Some
examples of our products would include fare-gas recovery
system and sulfur recovery system.
The Flare-Gas Recovering System is used to recover useful
petrochemical by-products contained in fare gas, or waste
gas, commonly generated in a petrochemical refnery during
the production process. Flare gas contains fammable
and poisonous waste gas and is characterized by its high
temperature, fammability and volatility. Sunpower’s system
provides a cost-saving and environment-friendly solution,
as it helps our petrochemical clients reduce the discharge
of pollutants into the atmosphere, thereby reducing the
penalties imposed on them. Sunpower’s fare-gas recovery
systems have successfully penetrated into markets such as
Central Asia and Southeast Asia.
Sulfur recovery is carried out through Sunpower’s core
design team, where we utilise advanced technology and
EPC experience to provide one-stop services for our
customers in the oil refning, natural gas and coal chemical
industries.
