As coating professionals Blastech developed the REDI-PLATE™ Process to ensure that every facet of the plate coating process was carried out to the highest global standards.
Plates incoming to the facility are checked for conformity to bills of lading, on approval each plate is entered into the custom built Blastlogix data management system where they permanently reside.
As plates are loaded onto the conveyor they are examined for surface contaminants and if present removed to meet SSPC SP 10 NACE 2 Surface Preparation Specification.
The plate enters an enclosure where both top and bottom surfaces are simultaneously impinged with a mixture of steel grit and shot to both remove the mill scale and impart a dense sharp profile that will support the adhesion of the coatings that are required to protect the steel from corrosion.
The plates are then heated to ensure drying times.
After blast cleaning the plate are examined for quality and major surface defects and to ensure steel is free from dust. Following which they are checked for the important blast profile. This data is recorded in the Blastlogix system.
Next stage is to apply the special inorganic coating uniquely formulated to be safely welded without noxious fumes and good weld quality.
The special application equipment is custom built to Blastech’s specifications. The reciprocating spray guns are calibrated to ensure the industry agreed standard dry film thickness of 0.6 – 0.8 mils (15 – 18 microns) is evenly applied over the entire surface. Dry Film Thickness is verified by attaching smooth panels to both sides of the plate on entry to the coating module then measured after drying. The panel are retained and measurements are recorded in the Blastlogix data base. We retain independent reports for each and every plate we process in our data bass for both commercial and technical issues that may arise in the future.
After coating the information entered into Blastlogix at the start of the process, the plate is re-identified using a state-of-the-art UV cured ink marker with all traceability components the plates are re marked with the original markings plus any other information required by our clients before entering a drying tunnel to ensure that no damage occurs when lifting by magnets into positions for intermediate storage prior to order assembly and loading.
We have recently extended our REDI-PLATE™ process to comply with industry demands for the application of high build coatings to the top (exterior) surfaces of the plates.
After the abrasive cleaning to specification and before entering the coating module we create a nominal 4” bare area around the plate to facilitate later processing such as burning and welding.
In the coating module we apply the specified coating to the thickness required. Dry Film Thicknesses are verified and recorded.in our Blastlogix plate management system.
The plates are carefully stored with airspaces to allow for curing to ensure that shipping damage is minimized.
After curing the plates are shipped by truck or rail.
