Zinc coated steel pipe used in scaffolding pipe. In various construction activities, scaffolding pipe is considered very important component of galvanized steel pipe in any project because steel scaffolding has great strength and durability.ASTM A123 and G90 Specifications American Galvanizers PRE ZINC COATED STEEL PIPEMar 12, 20131 Pre-galvanized sheet tends to be very formable without cracking the galvanized coating because it is made almost entirely of eta layer (free zinc) and has very little alloying, unlike the hot-dip galvanized coatings produced using the batch process. This lack of alloying also means pre-galvanized sheet is less abrasion resistant than steel galvanized using the batch process.CMP Coatings - Contech Engineered SolutionsPre-galvanizing is the most widely used and most economical metallic coating for corrugated steel pipe and it protects and extends service life. In addition to forming a physical barrier against corrosion, the zinc coating sacrifices itself slowly by galvanic action to protect the base steel. This action continues as long as any zinc remains.

The melting point of zinc is at 419°C and the boiling point is around 908° . In welding, zinc is melted on the surface of the molten pool or at the root of the weld. Since zinc has a relatively high solid solubility in iron, the zinc liquid will deeply erode the weld metal along the grain boundary, forming Welding of Coated Steels : Total Materia ArticleWelding of zinc-coated steel can be done, but specific precautions should be taken. When galvanized steel is arc welded the heat of the welding arc vaporizes the zinc coating in the weld area. This is because the boiling point of zinc (1600°F, 871°C) is below the melting point of steel (2800°F, 1538°C).
Nov 18, 2020Galvanized steel pipe is a steel pipe that has been coated with zinc. This coating protects the steel from corrosion. It is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. It is also sometimes called galvanized iron pipe.
