Vacuum trucks are pressure sensitive equipment, generating massive negative pressure in order to suction liquid and debris. There is also an exposure to corrosive materials and liquids which can cause rust to internal components such as the holding tank, vacuum unit, and other pressure sensitive components. An ultrasonic tester can help to ensure the structural integrity of a pump truck for sale.

Testing Importance

Ultrasonic testing is part of a comprehensive preventive maintenance inspection for vacuum trucks that are used to handle various types of liquid. Some are used specifically in the oil industry, while others are used for sewage removal. While all such liquids can be safely handled, there is the potential to corrode truck components after prolonged use.

Certain liquid elements will eventually cause metal components to rust and thin, which can compromise the equipment’s safety. Different liquid types have different levels of acidity, so the rate at which corrosion takes place with the metal components varies. Testing has to be done as part of a comprehensive maintenance inspection to monitor the structural integrity of a tank.

Testing is also important whenever any equipment has been involved in an accident or the tank has been scraped or experienced an impact. This is important since the thickness of the metal of any impacted area may have been affected and its strength may have been compromised, making it prone to leaks. A test should be conducted when a utility company is looking to buy a used pump truck for sale or a vacuum truck is involved in any collision-type of accident to assess the vehicle’s road worthiness. It can also help determine the right approach for repairing the damage as well as determine if a component should be replaced.

Ultrasonic Testing Process

Ultrasonic testing is a nondestructive method of assessing the thickness of material such as steel or alloys and even concrete as well as wood. It is nondestructive because the thickness of the material is simply assessed by using ultrasonic pulse waves. Such an approach is ideal for vacuum trucks because of the tubular shape of most vacuum truck components including the holding tank. It would be impossible to use any other tool to physically measure the thickness of the metal that makes up the tank.

An ultrasonic tester works by shooting pulse waves ranging from 0.1 to 15 MHz via a transducer. The waves travel through the metal or any other material; once the wave hits a dead end, it is reflected and bounces back towards the device. Thickness is then measured based upon the amplitude or intensity of the reflection received as well as the amount of time taken for a signal to be received. From these two pieces of data, the device is able to accurately gauge the thickness of the material.

Advantages

This method offers several advantages:

  • Minute variations in thickness can be detected, making it possible to find the tiniest defects.
  • Measurements can be performed regardless of the thickness of the metal, making it ideal for assessing various vacuum truck components.
  • Continuous testing can be done on large sheets of metals, such as the entire length of a holding tank to accomplish a quick and thorough inspection.
  • The device is portable, so an inspection can be done anywhere and at any time.

Vacuum truck inspections are important because of the continual exposure of the vehicle and its part to caustic liquids that could damage vital components. Ultrasonic testing is a novel device that makes it convenient to assess the thickness of critical parts nondestructively, accurately, and conveniently. Using such a method to find small deficiencies in vacuum truck tanks can lower risks and better preserve equipment!
