Differences Galvanized Steel Pipe And Seamless Steel Tube

Galvanized steel pipe due to corrosion resistance and wear resistance is stronger, is generally used for fence, fence, railing, balcony guardrail, etc, have been widely applied in municipal. Engineering, roads, factories, schools, development zones, garden, plaza, community and so on.Seamless steel tube standard chemical and mechanical pipeline, because of their large size so widely used in petroleum chemical industry, machinery manufacturing and other industries, seamless steel tube because of its weight is bigger, so the more expensive than galvanized steel pipe in the market.Galvanized steel pipe in part on the surface of seamless steel tube with a layer of zinc plating, galvanization steel tube is not fixed, the kinds of possible raw material is welded pipe, seamless tube is likely to be.Galvanized steel pipe corrosion resistance than the seamless steel pipe, seamless steel tube of the carrying capacity of better than galvanized steel pipe, galvanized steel pipe due to the existence of the galvanized layer is not susceptible to oxidation rust, and seamless steel tubes for tube wall is thick, the natural weight bearing capacity is strong, and galvanized steel pipe is suitable for some of the places in the outdoor, and seamless steel tube is suitable for the underground pipe laying, actually they can supplement each other, how to choose the manufacturer of galvanized steel pipe or seamless steel pipe according to the specific requirements for choice.Hot-dip galvanized steel surface layer plated or galvanized welded steel pipe. Galvanized steel to increase corrosion resistance and prolong life. Galvanized pipe is widely used, except for water, gas, oil, generally low-pressure fluid line pipe, also used oil heater oil industry in particular, marine oil wells pipes, pipelines, chemical coking equipment, condensing coolers, washing coal distillate oil exchange Used tubes, as well as the bridge piles, mine tunnel support frame with a pipe. Galvanized pipe is molten matrix metal and the reaction of the iron alloy layer, so that the substrate and coating combination of both. Galvanized pipe is first pickled, the steel surface in order to remove iron oxide, after pickling, cleaning tank by mixing an aqueous solution of ammonium chloride or zinc chloride and zinc chloride or ammonium chloride solution, and then into hot dip tank. Galvanized with coating uniformity, strong adhesion, long life and other advantages. Hot dip galvanized steel substrate galvanized pipe with molten bath complicated physical, chemical reactions, the formation of corrosion-resistant zinc-iron alloy structure closely layer. Alloy layer and layer of pure zinc, steel base blend. Therefore it resistant to corrosion. Seamless is a hollow cross section, no seams around the long bar of steel. Steel hollow sections, a large number of used pipes conveying fluids, such as transport oil, natural gas, gas, water pipes and some solid materials, and so on. Compared to other steel and solid steel bar, the same torsional strength in bending, lighter, seamless steel pipe is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle rack and construction using steel scaffolding. Ring with steel pipe manufacturing parts, can improve material utilization, simplify the manufacturing process, saving material and machining time, such as bearing rings, jack sets, has been widely used to manufacture steel. Steel or a variety of conventional weapons indispensable material, gun barrels to make steel. Steel shapes in different cross-sectional area can be divided into tube and shaped tubes. As in the perimeter of equal conditions, the largest area of a circle with a circular tube can carry more fluid. In addition, the circular cross section to withstand internal or external radial pressure, the force is uniform, so the vast majority of the pipe is pipe.
