Non-alloyed materials used to manufacture threaded or welded pipes are produced under standard EN 10255. A number of options are provided by this standard for the finish of the EN 10255 Pipe ends and coatings. 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.
Zinc is an element that offers superior resistance to atmospheric corrosion. And since the layer of zinc coating is much thicker in comparison to a plain electroplating layer, the chances of corrosion in an EN 10255 Hot Dipped Galvanized Steel Tube is much lower. Another coating suggested by most manufacturers is blackening, where the Welded Steel Pipe BS EN 10255:2004 is coated with a layer of black oxide, thereby reducing its light refection, while offering a milder form of corrosion resistance properties. This particular standard envelopes en 10255 steel pipe which are produced with a specified outside diameter ranging between 10.2 mm to 16551 mm or the size of the thread ranging between 1/8 to 6 inches. The standard also covers EN 10255 Non-Alloy Steel Tubes in two series, i.e. - medium and heavy, in addition to three kinds of designated thicknesses. The suitability of light, heavy and medium EN 10255 Threaded steel tubes includes several applications including Fire Fighting, Gas lines, HVAC lines, water lines (Cold & Hot) as well as Electric Poles. One of the main functions of these pipes is the transportation of fluids and petroleum.
