Pipework
Pipework generally comes in a wide variety of shapes and sizes.
Frequently it is coated internally and externally in a protective varnish or paint. This has to be removed prior to galvanizing and historically we could remove this contamination by burning it off in the molten zinc bath, followed by stripping the excess zinc off, then pickling the material.
However, recent changes to environmental legislation and new chemical control procedures within our process mean we are unable to clean material using this method and can now only remove paint contamination if it is within our blasting capabilities.
The solution is simple: always have pipework shotblasted. This can be made even easier by carrying this out prior to fabrication, making it less complicated for the shotblaster.
Please ensure your material has no paint contamination internally and has been completely shot-blasted prior to arrival. Should you have such material please contact our design team for advice on what to do before sending it for galvanizing.
