What is the benefit of using steel pipe?
After rinsing out rusted surface in acid, steel pipes are dipped into a bath of molten zinc and kept there for some time. The internal as well as the external surface of the pipes get a thinner film of zinc and such pipes are called galvanized pipes. The galvanized steel pipes of various nominal bores are used as water pipes by laying them underground for supply of water for public utility. Because of the anti-corrosive quality of zinc, water does not react with steel and rusting and corrosion are checked. These underground water supply systems facilitated by galvanized steel pipes last longer with almost zero maintenance cost. The benefit of using Steel pipes goes to the public in the shape of saving for the local government.
Steel pipes come in a variety of forms and structures depending upon their end-use such as Steel Pipes and Tubes, Hot Dipped Galvanized Tubes, Black Steel Tubes, Fence Tubes, Scaffolding Tubes, Structural Steel Tube. Steel strips of various widths and continuous lengths are formed into tubes; the two ends are joined by welding or by Electric Resistance Welding (ERW). Usually, structural steel such as angles, channels, joists and beams are used for constructional purposes. But steel pipes can be beneficially used for roofing structure like truss because of lower cost and higher tensile strengths. Galvanized steel pipes find beneficial use in mobile towers because they are exposed to atmospheric condition. These towers can withstand higher wind pressure with the involvement of lesser material cost in the shape of galvanized steel pipes as compared to the galvanized angles.
