The section requires the pipe to be hot-dip galvanized with a grade of zinc conforming to Specification B6, Standard Specification for Zinc and gives requirements for weight per unit area of the coating.
Hot-dip galvanizing is done in accordance with long established ASTM specifications. There are three main specifications (ASTM A123, A153, and A767) governing the coating thickness, adherence, and finish for hot-dip galvanized steel and a handful of supporting specifications referenced in these specifications; cover design practices, repair and touch-up, and painting/powder coating over HDG and GI diffrence - Carbon Steel Pipe and FittingsHDG and GI diffrence. Date:2017-02-18 keywords:hdg, gi. HDG:Also called hot dip galvanized and hot-dip galvanized:is an effective way of metal corrosion, mainly for various sectors of the metal structure facilities. Is immersed steel rust after about 500 melted liquid zinc, steel member attached to the surface layer of zinc, which serve the purpose of preservation.
The hot dip Galvanizing process The galvanizing process consists of three basic steps:surface preparation, galvanizing and in-spection. SURFACE PREPARATION Surface preparation is the most important step in the application of any coating. Any failures or inadequacies in surface preparation will immediately be apparent when the steel is withdrawn Hot Dip Galvanized Steel Pipe, Galvanized PipeHot Dip Galvanized Pipe. Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. Galvanizing is one of the most widely used to methods for protecting metal from corrosion.
Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to the steel.
