It's Not Just Filling a Tank with Water - Part 1

Hydro testing a tank is performed by a skilled team of Administrators, Coordinators, Designers, Operational management and highly-skilled technicians at NCS Fluid Handing Systems. At NCS Fluid Handling Systems we treat this important requirement of tank hydro testing with the all the right safety measures, design considerations and professionalism that is required to complete the entire Hydro testing Scope. It's not just moving water and filling a tank; hydro testing is an integral part of a tank asset's service life and overall value.  

While the main purpose of hydro testing storage tanks is to confirm the overall integrity of the tank and particularly the integrity of the shell, this is not the sole purpose of a hydro test. In addition, a hydro test is intended to support a full operational test using a safe medium with a specific gravity greater than that designed for cargo.

Testing also:

• Tests the foundation for proper support of the tank and uniform settlement,
• Confirms that the floating roof travels freely during normal filling/emptying operation,
• Confirms the toughness properties of the plate steel against brittle fracture,
• Checks for any design or fabrication deficiencies, and
• Confirms integrity of major modifications or repairs done
