Sandblasting or shot blasting IS the use of an abrasive medium offers the best method of cleaning mill-scaled and rusted surfaces. This method involves mechanical cleaning by the continuous impact of abrasive particles at high velocities on to the steel surface.
Sandblasting & Shot Blasting for Steel Pipe and Tube
Sandblasting is a process where sand is blasted at steel or metal to remove rust, paint, or oil on the steel. Shot blasting is a similar service used to clean steel. However, shot blasting uses tiny steel balls to clean steel pipe and tubing. Shot blasting is popular because it creates a unique texture to the steel and promotes better paint adherence.
Sandblasting and shot blasting are quick, cost-effective, and prepare steel surfaces for further processing.
Sand blasting and shot blasting are both mechanical surface cleaning processes and are often confused.Let’s see what’s the difference between and blasting and shot blasting?The main difference between them is that they have different working principles and applications.
Shot blasting is to use the centrifugal force of the high speed turntable to throw the steel shot to the workpiece surface.After processing, the workpiece will produce finishing effect, pressure stress, improve the fatigue strength.Compared with sand blasting, sand blasting does not produce silica dust and causes less environmental pollution.
Sand blasting takes compressed air as its power and shots the high speed abrasive sand stream to the surface of work piece. Due to the impact and cutting action of abrasive sand, the workpiece surface is completely clean, while the surface quality and mechanical properties are greatly improved.The processed workpiece has better fatigue resistance and adhesion, which helps the coating to be smooth, and the service life is longer.
Sand blasting is the main function of surface rust, remove oxide, such as parts after heat treatment, and shot blasting action and function is more.Not only rust, surface oxide, but also improve the surface roughness, remove machining burrs, eliminate the internal stress of parts, reduce the deformation of parts after heat treatment, improve the surface wear resistance, compression capacity, etc.
The decision on which blasting technique to use depends entirely on the materials used in your equipment.
Because shot blasting systems blast sand at a higher rate, shot blasting clean systems are usually best for metal surfaces that are more difficult to clean.For example,shot blasting can easily remove rust from a metal surface or peel off paint.Sandblasting, on the other hand, is often used to make finer materials, such as plastics, aluminum, wood, stone, glass, or machinery with sensitive electronic components.
Longtaidi is a professional piping supplier. We can provide these two kinds of sandblast pipe products,such as elbows,reducers, Tee and cross, bends and prefabricated products etc.
After sandblasting or shot blasting, paint adheres better to the steel, galvanizing is even stronger, and fabrication becomes much, much simpler. Sandblasting provides new steel with a mildly abrasive cleaning, so you are left with a smooth surface free of imperfections.
This is the sandblasting area in Longtaidi Pipe Technoloy.
