Internal Blast & Paint Equipment

This equipment is intended for application of various liquid products, based on specifications supplied by the customer.

The pipe is placed on racks and staged for introduction into the stations. Pipes are individually rolled to the indexing station where the pipes will be manually rolled to the proper placement so that the pipes will all be at the exact same alignment on the lance entrance side. The rotation lift mechanism is then activated. The rotation station lifts under the pipe, raising the pipe above the pipe rack, allowing the rotation of the pipe. The blast cart drive system is activated which moves the lances into the pipe.

The blast pot mounted on the blast cart is activated, releasing abrasive through the lance and into the pipe. The pipe is blast on the inter-section stroke. All abrasive is captured in the blast media catch cabinet, which is mounted on tracks and activated to drive forward to capture the ends of the pipe before blasting commences. The abrasive falls to the bottom of a catch cabinet where it will be augured continuously to an elevator and rotary screen where the abrasive is gleaned and continuously dumped onto a return conveyor, which carries the abrasive to the abrasive holding bin. The holding bin will be supplied with a control valve for re-loading the blast pot.

After blasting the rotation station is lowered and the pipes are rolled down to the paint station where individual pipes are rolled into place. The paint lance is activated, moving into the pipe. The lance blows down the inside of the pipe upon the inter-section stroke and paints via an air driven spin head upon retraction. Negative pressure is pulled through the pipe via a spray booth. The spray booth is supplied with replaceable media to catch over spray. This booth is ducted outside for evacuation of fumes.
