Dec 25, 2017 · ASTM A53 is for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless. ASTM A53 contains seamless steel pipe and welde d steel pipe black and hot-dipped galvanized steel pipe in NPS 1/8 to NPS 26. The steel categorized in this standard must be open-hearth, basic-oxygen or electric-furnace processed and must have the following chemical requirements: Advantages and processes of hot-dip galvanizing square tubeDec 20, 2018 · Hot dip galvanized square tubes are steels used in hot dip galvanizing processes. This process is a maintenance of steel itself. The medium of steel is prone to oxidation problems, and the application of hot dip galvanizing technology can prevent oxidation of steel. A thick, dense layer of pure zinc masks the exterior of the steel, preventing contact with any solution and keeping the steel
hot dip galvanized steel pipe,first acid pickling to remove iron oxide,then clean,finally sent to the hot dip plating tank. The zinc layer is uniformity,strong adhesion,long service life,etc.So the corrosion resistant ability is very best.

EN 10255 steel grade s195t Specialize in. EN 10255 L1 series steel Large Diameter Pipe. EN 10255 H DIN 2441 Condenser Tube.
One of the most common surface finishes used on these non-alloyed pipes is galvanization. In this process, an EN-10255 Threaded Steel Pipe is dipped in a hot vat of solution that contains zinc. The molten zinc gets attached to the surface of the BS EN 10255 Steel Pipe, thereby covering every inch of the steel with a thick layer of zinc. Galvanized mild steel pipe, Galvanized Pipe - Sunny SteelGalvanized mild steel pipe for molten metal and iron matrix after a certain reaction with a layer of alloy layer, so that presents the effective combination between substrate and coating, and galvanized pipe can there are two ways to get, is a kind of hot dip galvanized pipe, and tprocess is the first to effective pickling of steel tube, then you can, removing fehe other is electric galvanized, hot galvanized pipe production rric oxide on the surface of the steel tube effectively will steel Hot Dip Galvanized Square and Rectangular Steel TubeHigh quality Hot Dip Galvanized Square and Rectangular Steel Tube from China, China's leading Hot Dip Galvanized Steel Pipe product market, With strict quality control Hot Dip Galvanized Steel Pipe factories, Producing high quality Hot Dip Galvanized Square and Rectangular Steel Tube products.
