Tank Structure and Operating Principle
Tank Structure
Tank Structure
  • 1Shell including the legs, lifting lugs, flange for fixing the membrane, is usually made of carbon steel or stainless steel.
  • 2Bladder made of EPDM or heavy butyl.
  • 3The cavity between the shell and the bladder is pre-charged with 20-40PSI gas, air or nitrogen for your options.
  • 4Embedded pressure gauge.
Operating Principle
Operating Principle of the Tank

When the pump starts or the pipeline pressure suddenly increases significantly, the air cushion in the cavity is compressed, the volume becomes smaller, and the pressure in the pipeline is absorbed, so that the pressure in the system reaches a balanced state. When the pump stops running and the pipeline pressure is released smoothly, the air pressure in the pressure tank is gradually released to ensure that the pressure in the system is in a balanced state until the pressure is released and the pump is restarted or the pressure in the pipeline surges again, forming a cycle.

Application Scenarios
Hydropower
Hydropower

Expansion tanks are used in hydropower systems to stabilise the pipelines' water pressure and flow rate. They help prevent water hammer, a sudden pressure surge that can damage pipelines and equipment.

Irrigation
Irrigation

Expansion tanks can be used in irrigation systems to regulate water flow to crops. They also provide a reserve of water that can be used during periods of high demand.

Potable Water Supply System
Potable Water Supply System

Expansion Tanks are used in water supply systems to regulate water pressure and prevent water hammer. They also provide a reserve of water that can be used during periods of high demand or when the supply is interrupted.

Fire protection
Fire protection

Expansion tanks can be used in fire protection systems to provide a reserve of water that can be used in case of a fire. They also help regulate water flow to prevent water hammer and ensure a consistent water supply to the fire sprinkler system.

Expansion Tank for Hydronic Heating System
Expansion Tank for Hydronic Heating System
Industrial processes
Industrial processes

Expansion tanks can be used in industrial processes that require a constant flow of water or other fluids. They help regulate the flow and pressure of fluids and prevent damage to equipment from the water hammer.

Frequently Asked Questions (FAQ)
What are the main advantages of using a replaceable EPDM bladder?
The replaceable EPDM bladder offers simplified maintenance and high cost-efficiency. It provides exceptional resistance to fatigue and aging, supporting an operational lifespan of up to 50 years under standard conditions.
How does an expansion tank protect pipelines from water hammer?
When system pressure spikes, the air cushion in the cavity is compressed, shrinking in volume to absorb the sudden pressure rise. Once the pressure drops, the air cushion expands, releasing back pressure to maintain system equilibrium.
What manufacturing certifications do these pressure tanks meet?
The tanks are constructed in compliance with major global regulations, featuring ISO9001, ISO14001, ISO45001, ASME, CE, PED 2014/68/EU (H model) certificates, alongside D1/D2 pressure vessel manufacturing licenses.
Can the tank structure parameters and design be customized?
Yes. Support for customized design solutions is standard, offering a wide array of options ranging from 3L to 20,000L volumes, multiple shell materials (carbon steel, stainless steel, duplex steel), and specific technical setups.
In which applications are these bladder expansion tanks typically installed?
They are ideal for regulating flow and pressure in hydropower pipelines, irrigation systems, potable water systems, fire protection sprinklers, hydronic heating applications, and constant-flow industrial processes.
What kind of shell coating and welding technology is applied?
German-standard professional welding technology is utilized for structural durability and clean finishes. The exterior is coated with water-based, eco-friendly paint to maximize corrosion resistance while reducing environmental impact.
