Tube Inwall Sand Blasting Process

Sand blasting is widely used in surface finishing. Workpiece surface can obtain certain cleanness and different roughness that contribute to better mechanical property and improve workpiece lifespan. Sand blasting machine has various applications, but what about some special workpiece such as tube inwall sand blasting process? iAbrasive gives a few instructions on special tube inwall sand blasting.

A set of compression sand blasting machine and an air compressor (airflow should be over 6 cubic meters per minute) are needed when performing tube inwall sand blasting process. The working procedure is simple: connect the hosepipe of sand blasting machine with tube inwall cleaner and push tube cleaner to the top and grad backwards, cleaning job can be done. The travelling speed depends on concrete cleanness and workpiece internal original condition. The equipment working principle is to make use of high-speed mixed air abrasive grain from sand blasting machine to be injected into tube inwall cleaner conical nozzle and make abrasive grains spread in conical contour, thus tube inwall can be impacted to achieve cleaning process.
