After the hop-dip galvanising, the pipes are generally quenched in the solution of sodium di/bichromate to protect the white rust formation on pipes. Generally it has been observed that the galvanised pipes do get white rust on their surface even after the sodium di/bichromate treatment, which mars the quality of the product.
Bright is a unique liquid chemical which when added into the quenching tank water, forms a coating of this chemical itself and hence generally eliminates the chances of white rust formation. It also increases the brightness of the pipes. The uses of bright vis a vis sodium di/bichromate is economical, as it costs less for unit tonne of steel pipes galvanised.
Bright is especially suitable for galvanising mild steel wires, pipes, sheet, structures, plane and threaded products and other miscellaneous mild steel items
