Product Overview
Product Overview
• PU flexible liquid storage tank and container is formed through thermal synthesis of
PU high polymer material coated fabric and can be divided into many types based on
shape, including pillow liquid storage tank, supporting liquid storage tank, supporting
liquid storage container, vehicle-mounted liquid storage tank and overwater dragging
oil bag.

Characteristics and advantages
Characteristics and advantages
Comparing with traditional steel tank, flexible
tank is small in size, thus lots of space and
transportation capacity can be saved.
The tank is made of oil resistant, water
resistant, aging resistant, corrosion resistant
and UV resistant material. Besides, it has
strong environmental adaptability and long
service life and is maintenance-free.
No large machinery is required and only few
people can quickly unfold it for use.Rapid
Light
Durable
It will not cause pollution to storage medium
and can store crude oil, oil product, drinking
water, chemical liquid cargo, sewage, etc.
Tank material is degradable.

Pillow liquid storage tank
Pillow liquid storage tank
Underground fracturing water and liquid storage
Working site of Daqing oilfield Jianghan fracturing working site in Xinjiang Working site of coal bed gas in Shanxi Hancheng
Working site of Shengli oilfield Working site of Shanxi Xiangning
• As unit volume is large, it is suitable for large amount of water preparation, liquid distribution
and fracturing operation at wide area.
• No support is required, storage and transportation size is small and hundreds of tons of
storage specification can be folded to several cubic meters.
Pillow liquid storage tank
Liquid storage during operation at oilfield.
• Usage unit/ scenario: operation group and mine area
• Product used: 400-500m3 flexible liquid storage tank
• Usage: wash water injection well and washing can be carried out in a continuous
manner, which can solve the problem of inadequate washing caused by discontinuity of
connection of tank truck and improve washing quality.

• Usage unit/ scenario: operation group
• Product used: 500-1000m3 flexible liquid storage tank
• Usage: wash main line of water injection well. As the storage space is large, it can make
the washing of main line more thorough and then solve displacement restricted due to
environmental protection.

• Usage unit/ scenario: operation group
• Product used: 20-50m3 flexible liquid storage tank
• Usage: operation of oil-water well Waste liquid produced in operation process can be
put into storage tank and then the problem such as overflow and blowout can be solved.

• Usage unit/ scenario: operation group
• Product used: 50-100m3 flexible liquid storage tank
• Usage: temporary storage of incoming liquid during pipeline head connection and inter-
station transformation As well needs to be stopped temporarily during construction of
pipeline head connection and inter-station transformation, this device could be used as a
temporary storage tank to store the incoming liquid temporarily before it is taken away
by tank truck. In this way, output lose could be effectively reduced.

• Usage unit/ scenario: operation group
• Product used: 50-100m3 flexible liquid storage tank
• Usage: profile modifying and plugging of injection well, and temporary storage, solving
the problem that tank trucks wait for water injection.

• Usage unit/ scenario: well drilling and perforation group
• Product used: 500-1000m3 flexible liquid storage tank
• Usage: storage of water liquid during well drilling and measure transformation process
Waste liquid produced during well drilling, fracturing, perforation and overhaul could
be put into storage tank directly. It is especially useful when waste reservoir needs be
constructed due to well drilling or large fracturing reformation.

• Usage unit/ scenario: transfer station of united station
• Product used: 100-200m3 flexible liquid storage tank
• Usage: it can be used as standby storage tank. It can be used in a convenient and fast
manner, and better effect can be achieved when used as emergency processing storage
tank.

• Usage unit/ scenario: handling of environmental protection accident
• Product used: 50-100m3 flexible liquid storage tank
• Usage: when pipeline perforation, casing leakage or other crude oil leakage accident
occurs, collection measure could be taken rapidly to control pollution scope.

friendly and not clean
Pillow liquid storage tank
Large liquid storage pool
• Multiple groups of pillow liquid storage tank could be connected in a series parallel manner to
set up a large liquid storage pool, which can be expanded without restriction if permitted by
site condition.
• It can be used as a temporary or movable liquid storage station.
• It can be used as temporary transfer storage when main pipeline has not been formally
connected.
Supporting liquid storage tank
and container
Supporting liquid storage tank and container
Horizontal supporting liquid storage container • It is mainly used for water storage and liquid distribution at underground fracturing site of oilfield and unit
volume is 40-50m3.
• The wide opening at upper part is convenient for liquid distribution and the outlet at lower part connects
with pipeline. Working site can be flexibly arranged.
• It replaces horizontal steel tank and water tank and be kept in a folded manner, which can save 5-7 times of
storage space and vehicle carrying capacity.
• Inner container and support is connected in advance, thus it can be conveniently unfolded. It can be rapidly
unfolded and set up by people or many kinds of engineering machinery.

Supporting liquid storage tank and container
Vertical supporting liquid storage container • It is mainly used for water storage and liquid distribution at underground fracturing site of
oilfield and unit volume is 40-50m3.
• The wide opening at upper part is convenient for liquid distribution and the outlet at lower
part connects with pipeline.
• Single land occupation area is smaller and the arrangement of operation site is more flexibly.
• It replaces horizontal steel tank and water tank and can be kept in a folded manner, which can
save 6 times of storage space and vehicle carrying capacity.
• Inner container and support is connected in advance, thus it can be conveniently unfolded. It
can be rapidly unfolded and set up by people and crane.
Supporting liquid storage tank and container
Ultra-large supporting liquid storage tank
• It is mainly used for water storage and liquid distribution at underground fracturing site of
oilfield and unit volume could reach 1100m3.
• Multiple groups of outlet at lower part are connected with pipeline.
• Single volume is large and utilization efficiency is high.
• It replaces large solid storage tank or excavation liquid storage container and can be kept and
transported in a folded manner.
• It can be easily unfolded and rapidly set up by people and crane.
