Detect, Prevent, Repeat: Routine Inspections to Keep Corrosion and Sediment at Bay

Storage tanks and pumps need to be inspected often to stay healthy and work well for a long time. Routine inspections help in quickly finding and fixing problems like corrosion and sediment buildup. By doing so, damage can be prevented, and processes can run smoothly.

In this article, we’ll talk about the three most essential things to do to keep corrosion and sediment under control: detect, prevent, and repeat. Other routine checks are also very important for keeping storage tanks and pumps in good working condition.

A. The Detect Procedure

Regular inspections are the first stage in maintaining storage tanks for water and pumps to detect early signs of corrosion and sediment accumulation. By identifying these problems early on, preventive measures can be taken to avert further harm. The “detect” procedure consists of the following essential components:

1. Visual Examinations

Routinely inspect the exterior, joints, connections, and pump components of the storage tank for visible signs of corrosion, such as rust patches, pitting, or discoloration. Visual inspections aid in determining which areas require further investigation or immediate maintenance.

2. Nondestructive Examination (NDT)

Utilize non-destructive testing techniques, such as ultrasonic testing or radiography, to measure the thickness of tank walls and detect corrosion that is concealed from view. This allows for a thorough evaluation of the tank’s structural integrity and facilitates proactive measures.

B. The Prevent  Procedure

Prevention is essential for mitigating the dangers posed by corrosion and sediment accumulation. Implementing preventive procedures reduces the likelihood of significant damage and expensive restorations. The “prevent” procedure consists of the following preventative measures:

1. Cathodic Security

Install cathodic protection systems, such as sacrificial anodes or impressed current systems, to neutralize corrosion-causing electrochemical reactions. Cathodic protection preserves the structural integrity of storage containers and prevents corrosion from occurring or advancing.

2. Coating and Linings

Apply the appropriate coatings and linings to the storage tank and pump interiors. These protective layers serve as a barrier between the stored substances and the tank, minimizing corrosion and sediment adhesion.

2. Fluid Evaluation

Examine the chemical composition, pH levels, and other pertinent parameters of the stored substances regularly. Fluid analysis aids in the identification of any factors that contribute to corrosion or sediment formation, allowing proactive measures to be taken to mitigate these risks.

C. The Repeat Procedure

Regular inspections should be repeated at regular intervals to ensure the continued health and performance of storage containers and pumps. The “repeat” procedure includes consistent monitoring and periodic evaluations. The subsequent repeated examinations are required:

1. Periodic Evaluation of Structural Integrity

Conduct routine inspections of the structural integrity of the tank’s walls, supports, and foundation. This evaluation should also evaluate the structural integrity of the pump’s components. By identifying any symptoms of deterioration or weakness, prompt repairs or replacements can be performed to prevent significant damage.

2. A Sampling of Sediment and Analysis

Periodically collect and analyze sediment samples from the tank. This helps determine the composition and potential dangers of the substance. By monitoring changes in sediment characteristics, maintenance decisions, such as frequency of cleansing or removal, can be made and implemented.

3. Examining for Leaks

Conduct leak detection tests to locate probable entry locations for water or other fluids. Pipes, valves, and joints should all be checked for tightness and a good seal. The sooner leaks are found and fixed, the less chance there is of future deterioration or damage.

4. Evaluation of Pump Efficiency

Check the energy usage, pressure, and flow rates of the pumps regularly to evaluate their efficiency. Pump inefficiency or potential mechanical faults are only two examples of the kind of problems that might be revealed by a departure from typical operating conditions. Pumps can be damaged from either overuse or insufficient flow, so keeping an eye on how they’re doing is essential.

5. Protective Coating Examining

Inspect the condition of protective coatings and linings applied to the surfaces of storage containers and pumps periodically. Examine the surface for signs of flaking, cracking, or degradation. To maintain the protective barrier against corrosion and reduce the likelihood of sediment adhesion, coatings that have been damaged should be rectified or replaced immediately.
