What is Abrasive Grit Blasting? (aka Sandblasting) - TWI
The first abrasive blasting process was patented on 18 October 1870 by Benjamin Chew Tilghman and, in essence, the process has used the same basic technique ever since. While there are variations in media type, blasting techniques and equipment, all abrasive blasting involves a material being propelled at a surface for the purpose of surface treatment or cleaning. The properties of the blasting media used depends on the application; from softer, less abrasive media like walnut shells through to See more on twi-global cold finish steel pipe for construction material Sand blastingWhat can steel shot be used for in sandblasting?Steel shot is very durable for use in sandblasting application and has a high ability to be recycled. Since the media is spherical in shape, it is an effective media for finishing and preparing for coatings. Steel shot also has very low dusting. In addition, steel shot can be used in both wheel blasting and pneumatic (air) blasting.See all results for this questionTABLE OF CONTENTSMaterials, other than pipe and fittings, which are to be placed within the trench limits and below finished grade, shall conform to the minimum standards hereinafter referred to.

The etching and scratching in the surface prepares the surface so that the paint bonds and sticks with it. Without this step, paint chips more easily. Sandblasting strips the oxidation off of the steel.
