If air gets closed in and cannot escape, or if liquid is left in the object, hazardous situations can result and there may be very serious consequences for the people working at the galvanisation plant. The temperature in a zinc bath is 450°C.See all results for this question

    What's the minimum hole size for hot dip galvanizing?

    Minimum hole size is ø10mm Hole diameters should be at least the same size as the steel thickness. Having bigger holes (where feasible) is always better for the galvanizing outcome. Refer to 'Hollow Sections'for applicable hole size charts. Refer to 'Hollow Vessels 'for applicable hole size chart. 9 Design Guide for Hot Dip Galvanizing See all results for this questionWhat's the best way to hang hot dip articles?For long, straight sections, 2 lifting lugs are preferred to avoid wire or chain marks. Where possible, articles are hung on a 45° angle (approximately) to ensure efficient drainage of pre-treatment solutions and molten zinc. This avoids rough surfaces and lets the air escape from the highest point, preventing explosions.See all results for this questionVANESSA IMEX - Steel PipesDrill Pipe, Drill Collars, Heavy Weight Drill Pipes.

    Drilled holes essential for galvanisation - Rotocoat

    Holes for suspension. Before an object is galvanised, it has to be suspended on a traverse. Using wire or hooks almost always leaves a "scar". So it is preferable to drill holes in the top and bottom of the object for suspending it on the traverse before it goes through the entire process of pre-treatment and galvanisation. Advice about holesDo you drill holes before or after galvanisation?Before an object is galvanised, it has to be suspended on a traverse. Using wire or hooks almost always leaves a "scar".
