Shot blasting is a type of surface preparation that is limited in its usefulness, especially in comparison to the more effective shot peening finishing treatment.
The “shot” in shot blasting refers to the small steel balls of various sizes that are placed into the shot blasting machine. If you have seen this method in action, then you know about its limitations producing the desired result for industrial parts used in oil and gas.
Examples of When Not to Use Shot Blasting
Consider these examples of when shot blasting is not the ideal choice to treat oil and gas parts.
1. When You Want Metals to Last
If you purchased metal parts with the intent for the parts to last for a prolonged period of time, then you absolutely should not rely on shot blasting.
Shot blasting can severely damage metal and make it weaker, causing the parts to break much sooner than they should.
Metal normally has a long lifespan — unless it is very damaged. Shot blasting can damage all kinds of metal and will cost you time and money in the long run.
2. If You Want to Create a Smooth Texture
Shot blasting does not leave a smooth, soft finish on metal parts — or any other surface.
Oil and gas professionals typically want their materials to be smooth and easy on the eye, instead of appearing to be rough and brittle. Because shot blasting does not leave a pretty finish on metal, this approach does not work if you want to create a professional look.
3. If You Want to Remove Tensile Stress
If you are looking to curve or straighten metals and other materials with no tensile stress, then shot blasting is not the way to go.
Shot blasting can damage metal and leave rough marks on the surface. Using shot blasting as the method for this type of project could ruin the material.
Why is Shot Peening the Ideal Alternative to Shot Blasting?
Shot peening is the ultimate solution for each of these examples. Shot peening will leave a soft, smooth surface on metal, and will make all of your materials look professional.
Also, the shot peening treatment allows metal to be curved or straightened without any tensile stress. It will also increase the lifespan of metal parts — saving your company time and money.
