Surge Vessels

Crucial Part of Your Pipeline Operation Integrity; Safe, Reliable and Sustainable

ERGIL Surge Protection & Water Hammer System is a powerful and user-friendly control system that protects your pipeline against water hammer & pressure transients for potable water, sea water and wastewater applications.

Water industry is being challenged with water scarcity, increasing construction, break-down, and maintanance costs, therefore continued operation has become more important than ever.

ERGIL Surge Protection & Water Hammer System protects not only humans’ life, but also your pipeline, pump stations, hydrants, valves, and other related equipment.

ERGIL designs and manufactures both bladder type and compressor type surge vessel systems.

Best Internal Bladders

Bladders are the most critical part of any air-in & water-in surge vessels. ERGIL’s years of experience, search and development projects help to understand how and what kind of bladder vessel to use. Choosing the right bladder plays an important role for the integrity of the system. Bladders are fragile items in nature and have to be designed with extra protection. Since, it is in direct contact with the water, it effects human life; therefore we offer certified bladders for potable water (drinking water) applications.

ERGIL manufactures;

  • Butyl Rubber (BR),
  • Polyurethane (PU),
  • Polyvinyl Chloride (PVC) type bladders.

Upon request, we also provide WRAS (UK Water Regulations Advisory Scheme) & Non-Toxic Certificate.

Compact Design

Compact Design

ERGIL’s compact skid bladder & compressor type vessels provide all you need on a single skid. ERGIL designs mobile or permanent frames, so moving from one place to another and using it for multiple pipelines is possible.

They are easy to transport from one location to another. Modules can be designed as per the shipping method (sea, road and even air) and the system can be customizable as per working environment to protect against rush weather effects or robbery.

Traditional surge vessel system contraction is costly, takes time, and safety concerns are high, however ERGIL’s mobile modular surge plug and play systems can reduce your project cost and time drastically in addition to eliminating site accidents. Contractors do not need to deal with site installation of such complicated.

Certified Pressure Vessel Manufacturer

ERGIL has been designing and fabricating engineered to order high pressure vessels since 1982. Surge vessel is the most important part of the water hammer system.

Designing and manufacturing high surge vessels requires certain specialization that has to be accredited by industrial authorities.

With more than 40 years of engineering experience and the trust of numerous successfully completed projects, we are always at your side.

Certified Pressure Vessel Manufacturer


  • Renowned company understanding of surge system design
  • Ensures compliance with Product Equipment Directive & ASME regulations
  • Reduces water leakage
  • Pipeline fatigue and bursts analyze
  • Minimizes risk of contamination in potable water pipes caused by negative pressures
  • Accommodates variable pumping regimes without dumping compressed air
  • Improves your company’s environmental social responsibility and public image
  • Vertical or horizontal types are available
  • The bladder is designed so it can expand to the full size of the vessel. This allows for greater drawdown volumes and less stress on the bladder.
  • The air is trapped in the space between the outside of the bladder and the wall of the vessel. Therefore the liquid is not in contact with the steel walls of the vessel.
  • Depending on the level of cubage in the tank it is possible to design by using minimum 3, maximum 4 legs as optional
  • Design code: ASME and others


ERGIL designs and manufactures pressure vessels up to 900 bar with maximum thickness 220 mm. Our fabrication facility and personnel are certified with ASME U, S, R, NBR, GOST, AD 2000/ISO 3834, EN 1090-1, EN ISO 3834-2, & DNV GL + ABS Marine Welding Class Program and capable of designing and manufacturing as per ASME, EN, GOST & as per end user requirements; such Shell DEP.

Fully Automated Systems

Fully Automated Systems

Are you interested to control your surge vessel operations automatically and monitor operations from your control room? System can also be monitored and controlled from our smart App and send SMS or e-mail notifications. ERGIL provides full automated surge vessel systems that can be integrated into your existing control system. Having an automated system helps you to reduce man power manual help, accident risks and equipment hazards.

ATEX Certified SCADA Control Panel

ATEX Certified SCADA Control Panel

Skid system comes with an certified SCADA control panel. System works with Modbus communication or similar protocols allowing remote reporting of all events.

Once, the system analyzes safety requirements and pressure ratings through sensors and actuator pressure relief valves, and sends a signal to the control room.

System automatically absorbs the pressure. Control unit captures the real time data. Besides traditional models, wireless controlled data transfer is also available upon customer requests.
