Division I sold to Hebei, Tianjin, Beijing, thin-walled galvanized pipe, greenhouses, hot galvanized steel pipe. Galvanized pipe specification is complete, multi-brand, as YHI galvanized pipe, Lida hot galvanized pipe, Dongsheng galvanized pipe. The YHI galvanized pipe galvanized steel pipe weight coefficient nominal wall thickness mm 2.0 2.5 2.8 3.2 3.5 3.8 4.0 4.5 Youfa galvanized pipe coefficient parameters: c 1.064 1.051 1.045 1.040 1.036 1.034 1.032 1.028 Note the mechanical properties of steel is to ensure that the steel end-use performance (mechanical properties) Youfa an important indicator of galvanized pipe, it depends on the chemical composition and heat treatment of steel. Steel standards, depending on the requirements of the provisions of the tensile properties (tensile strength, yield strength or yield point elongation) and hardness, toughness, user requirements, high and low temperature performance. Youfa galvanized pipe steel grade: Q215A; Q215B; Q235A; of Q235. Galvanized steel pipe: to improve the corrosion resistance of the steel pipe, General Steel Pipe (clarinet) galvanized. Galvanized steel pipe hot galvanized and electrical steel zinc two hot-dip galvanizing galvanizing layer thickness, the low cost of electro-galvanized. Galvanized pipe sulphate electro-galvanized iron alloy process, is to the production trough and trough perforation direct solution bring out or overflow. Each step of the production process from the circulatory system. What is the galvanized pipe? Surface welded steel pipe hot-dip or electro-galvanized layer. Galvanized increase the corrosion resistance of the steel tube and prolong life. What is the use of galvanized pipe? Galvanized pipe is very versatile, except for water distribution, gas, oil, generally low-pressure fluid line pipe, the oil industry in particular is also used as a marine oilfield oil well pipes, pipelines, chemical coking equipment, oil heaters, condensing cooler, coal distillate wash oil exchange Used pipe trestle piles, mine tunnel support frame tube. Galvanized there several? There are two major categories of hot-dip galvanized and electro-galvanized. Hot dip galvanized wet, dry, lead, zinc method, oxidation reduction process as shown. The main difference in the method of hot galvanized steel acid leaching cleaning, what method of activating the surface of the tube to improve the quality of zinc coatings. Now used mainly in the production of dry-and oxidation-reduction method, electro-galvanized zinc coating surface is very smooth, dense, homogeneous; having good mechanical properties and corrosion resistance; the zinc consumption 60% to 75% lower than the hot-dip galvanizing. Electro-galvanized technically have a certain complexity, but to use this method for single-sided coating, a different coating thickness of the inner and outer surfaces of a double-sided coating, and a thin-walled tube galvanized mused.
