Electrogalvanising Procedure

2001

I'm in dire need for specification on electrogalvanising procedures in the field of laboratory application for oil & gas, petrochemical industry, hospital laboratories & for schools.

We would appreciate your response on the above requirements or any references with regards to this application.

Thank You.

Ed. note: "Electrogalvanizing" is simply another name for zinc electroplating, Mr. Mitchell. Our "must-have" booklist includes a number of electroplating books that will get you started. There is an awful lot to the subject, including dozens if not hundreds of MIL, ASTM, SAE, ISO, and other specs. Please post the details of your actual situation and the readers will probably help you. Good luck.

We have procured carbon steel threaded fittings (couplings, tees, etc.) with electro galvanising with 25 microns thickness instead of Hot-dip galvanising of 70 microns.
Is the electro galvanising is equal to hot dip galvanising in terms of protection from sea water.

Also give us the ASTM standard for electroplating.

Sorry, R., but 25 microns of zinc in not a proper substitute for 70 microns of zinc. It's only about 1/3 as thick and will only last about 1/3 as long. As mentioned there are numerous ASTM standards for electroplating, but a good starting point is probably ASTM B633
