PRD-Blast Systems
Pacific Roller Die Company, Inc., world leader of large diameter pipe manufacturing technology, has the additional product line of PRD-Blast internal pipe blasting and coating systems. The self-propelled rotary stripping system is engineered to rapidly clean pipe interior surfaces down to the white metal without requiring personnel to enter the pipe.
“Like a white tornado in a pipe, PRD-Blast cleans pipe easier, faster, and more economically than any blast-pot operation,” said Daniel D. Freitas, PRD Manufacturing Manager. “The system lowers labor and equipment costs as much as 75%, saves time with 360 degree rotary blasting, reduces hazards with remote controlled operation and eliminates human error commonly found with hand blasting.”
- Saves time by rotary blast cleaning the full 360 degrees inside of pipe surfaces with self-propelled forward or reverse motion
- Lowers labor costs as much as 75% compared with manual blast-pot operations
- Eliminates inconsistencies commonly found with manual blasting
- Reduces hazards with remote controlled operation
- No down-time with PRD-Blast TM extremely reliable operation
- Adapts for various blast media and coating applications
- Adapts to blast pipes clean to white metal or required specifications in a wide range of diameters
- Applications to clean internal pipes, windmill tower fabrications, vessels, tanks, penstock, tanker trucks and metal containers with minimal set-up
PRD-Blast systems consist of a self-propelled cart, remote controls, rotary head, and rotary diffuser with two-three nozzles. As the self-propelled PRD-Blast system travels through the metal pipe, rotating nozzles blast the surface clean. With the same working principle PRD offers machines for painting/coating applications.
PRD-Blast and painting systems are available for drive-through operation on pipes from 10 inches to 31+ feet (254 mm to 9 m) in diameter. Utilizing PRD’s Lance Centering Tools, a lance system operation can be specified for smaller diameter pipes of 3.5 inches to 22 inches (90 mm to 560 mm).
The patented rotary self-propelled units reduce project equipment costs by eliminating expensive scaffolding, multiple blast pots, multiple air compressors and hoses. Using only two to three men to operate, the PRD system reduces labor costs substantially over blast-pot operations requiring a dozen men.
Pacific Roller Die Company, Inc. manufactures spiral weld seam and lock seam pipe manufacturing systems in addition to coating and lining systems. The Company has well over 200 systems worldwide and provides technical and professional assistance for planning, manufacturing, sales and marketing.
