REDI-PLATETM
Innovative Steel Plate Cleaning and Coatings Application Technology

THE FACILITIES:
At Blastech's two plant locations we offer an innovative, automated system for cleaning and application of specialized primer systems to steel plate with our REDI-PLATETM systems.  We also offer the unique Dry Plate Preservative (DPP) system which preserves blast cleaned plates and eliminates the use of oil to preserve the prepared surface.

THE PROCESS:
 
  • Incoming plates are marked and entered into REDI-PLATE data base materials management system.

    • Surface contaminates are identified and removed and then plates are cleaned with high volume air to remove moisture and debris prior to entering the blasting chamber.
  • Plates are abrasive cleaned to SSPC.SP 10/NACE No 2 near white metal specification utilizing a combination of steel shot and grit to achieve a dense sharp profile of 1.5 – 2.5 mils. 
  • Abrasive residue is removed with brushes and air cannon
  • Blasted plates are preheated to ensure surface temperature for coating.
  • Plate enters coating booth where automatic application of the Interplate inorganic weldable preconstruction primer coating is applied to 0.6-0.8 dry film thickness. Film thickness is measured using smooth steel control panels.  The multiple film thickness measurements are entered into the REDI-PLATETM data base materials management system.  The control panels are retained as a permanent job record.
  • The entire process is monitored with high definition cameras to view both sides of plates.
  • Quality records are completed for each shipment.
  • Completed plates may be flame, plasma or laser cut.
  • The coated plate surface is inspected for anomalies and the original heat numbers are applied to plate with paint sticks.  The REDI-PLATETM data base materials management system in combination with site storage for our diverse computerized customer base allows us to ship as required on a Just-In-Times basis from our 10 acre, rail served sites.

PROJECT MANAGEMENT:
Blastech project management systems ensure that all shop work is performed to meet and exceed your expectations. We also maintain strict quality control records and safety surveillance on all projects.
 

BENEFITS:
 
  • May be cut by any method. Rolled and shaped . Welded by any method with approval by the appropriate classification society.
  • Reduces need for post fabrication blasting by as much as 80%. Savings of 30% have been obtained. VOC and environmental costs have been virtually eliminated.  Welding and cutting produces fume levels below OSHA limits.
  • Eliminates cost of inspection to ensure plate surface is suitable for use. Eliminates down time waiting for replacement plates from inventory or mill.
  • Improved flow through shop.
  • Reduces damage by welding, cutting, etc.
  • Provides specified profile for application of weldable primer and subsequent coats, saving cost of post fabrication blasting.
  • No delamination or breaking of coating during fabrication, eliminating cost of touch-up.
  • Reduces cost and tracking for special primers for different coatings systems within the same construction project.
  • Improved coating system performance.
  • Reduces corrosion rate prior to finishing.
  • Saves the cost of weld splatter removal.
  • Only the weld itself needs to be surface prepared after fab.
  • Reduces cost in tracking plate. Allows for JIT delivery of plate with REDI-PLATETM , reducing fabricators' needs for inventory on site.
  • Allows fabricator to ensure that inbound materials meet required standards. Potential for reduction of incoming inspection costs.
  • Eliminates cost of touch-up of weldable primer.

DRY PLATE PRESERVATIVE (DPP):
DPP, the abrasive cleaning and coating of plate with specially formulated inorganic primers prior to fabrication, is cost effective and environmentally responsible, and eliminates the use of oil to preserve the abrasive cleaned surface.

Prior to processing the plate, we enter each plate into a database, recording all plate markings for re-marking on completion of the process. The plate is abrasive blast cleaned to SSPC-SP10/NACE No. 2, Near White Metal specification, through horizontal centrifugal blasting wheels using steel abrasive to provide a controlled profile of 1.5 - 2.5 mils. The steel grit is cleaned and recycled in a closed loop system.  Plates can be cleaned on one side only or both sides as desired.

The fabricator is able to flame, plasma or laser cut, shape and weld the processed plates to classification society standards with demonstrable cost benefits obtained from improved production and minimal surface preparation. The DPP fabricated product can then be coated with virtually any topcoat system.

Take advantage of this new service to North America and enjoy the savings associated with the use of DPP while avoiding the cost of environmental compliance associated with surface preparation and oils at the fabrication facility,
