Hot dip galvanized steel pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating are combined. Hot dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, the steel pipe is cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip galvanizing tank. Hot dip...

Tensile strength of galvanized steel pipe (σb): The stress (σb) obtained by dividing the sample's original cross-sectional area (So) by the maximum fully wetted force (Fb) endured by the sample when it breaks during the tensile process is called the tensile strength (σb), and the unit is N/mm2(MPa). It represents the maximum capacity of a metal material to resist damage under tensile force. Where, Fb-- the maximum force borne by the specimen when it breaks, N(Newton); So-- original...

Yield point of galvanized steel pipe (σs): The stress at which the specimen can continue to extend without increasing (maintaining constant) the force during the tensile process of a metal material having the phenomenon of yield. If the force drops, the upper and lower yield points should be distinguished. The unit of yield point is N/mm2(MPa). Upper yield point (σsu): the maximum stress of the specimen before the first drop in force due to yield; Lower yield point (σsl): the minimum stress in...

Properties of galvanized steel pipe: (1) Carbon; The higher the carbon content, the harder the steel, but the less plastic and ductile it is. (2) sulfur; It is harmful debris in steel. When steel with high sulfur content is processed under pressure at high temperature, it is easy to crack, which is usually called hot brittleness. (3) Phosphorus; Can make the plasticity and toughness of steel significantly decreased, especially at low temperature is more serious, this phenomenon is called cold...
