Containment / tanks and moulded products
Specify fiberglass containment around the stored fluid
CNPS supplies fiberglass storage tanks, double-wall configurations and moulded products. Fluid chemistry, capacity, temperature, loads, nozzles, installation and inspection define the design basis.
Containment routes
Define the vessel and every penetration
Nozzles, manways, vents, supports and instruments often control the practical design.
Primary containment
Define fluid, capacity, orientation, dimensions, operating conditions, corrosion barrier and support.
Secondary containment
State annular-space, leak-detection, inspection, drain and monitoring requirements.
Process interfaces
Provide nozzle schedule, flange standard, loads, manways, vents, drains, instruments and ladders.
Application-specific parts
Provide drawings, material duty, dimensions, tolerances, loads, finish and acceptance criteria.
Tank enquiry brief
Connect chemistry to mechanical design
A complete data sheet should cover the fluid, corrosion barrier, vessel geometry, loads and interfaces.
- Stored fluidComposition, concentration, impurities, temperature and cleaning regime.
- Vessel dutyCapacity, orientation, pressure, vacuum, fill rates, agitation and design life.
- Mechanical scopeDimensions, support, loads, nozzles, manways, access and instruments.
- Quality and deliveryStandard, inspection, testing, records, shipping, installation and schedule.
Direct answers
Containment selection boundaries
The responsible project engineer must approve final process, structural and safety design.
When should a double-wall tank be considered?
Where risk assessment, regulation or operating policy requires secondary containment or monitored leakage. The specific design and monitoring method must be defined by the project.
Can a tank be quoted from capacity alone?
No. Fluid chemistry, temperature, orientation, geometry, pressure or vacuum, loads, nozzles, supports, access, inspection and shipping constraints are also required.
Have a tank data sheet or nozzle schedule?
Send the fluid, capacity, temperature, pressure, geometry, loads, nozzles, standard, destination and schedule.
Frequently Asked Questions
What are fiberglass tanks?
Fiberglass tanks are storage tanks and vessels made of glass-fiber reinforcement in a thermosetting resin. They resist corrosion without internal coatings and are used for water, chemicals, fuels, and produced fluids.
Why use fiberglass tanks instead of steel?
Fiberglass tanks resist corrosion and scaling, weigh far less than steel, require less maintenance, and typically last longer in aggressive or high-salinity service, lowering total cost of ownership.
What fiberglass products does CNPS offer?
CNPS offers fiberglass and composite tanks and vessels alongside fiberglass pipe and related products engineered for oil and gas, water, geothermal, and chemical applications.
