API is an acronym for the American Petroleum Institute and is considered the most authoritative and comprehensive principle in the oil and gas industry. API 5B and API 5CT are mainly used for oil casing. API 5CT oil casing can be divided into seamless steel pipe...
Hot Dipped Galvanized Steel Pipe
Hot-dip galvanized steel pipe in the installation to the steel parts are first pickled, to remove the iron oxide skin on the surface of the steel parts, after pickling, but also through the ammonium chloride or zinc chloride aqueous solution or a mixture of ammonium chloride and zinc chloride aqueous solution to clean, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. Hot-dip galvanized steel pipe allows the molten metal and iron substrate chemical reaction, producing an alloy layer, so that the substrate and the plating are combined. The zinc layer of hot-dip galvanized steel pipe is thicker, with a thickness of 10um or more, and the surface is glossy but rough, and will appear shiny.
Galvanized welded pipe is divided into hot galvanizing and cold galvanizing. Cold galvanizing is generally used less. Hot dip galvanized pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and coating can be combined.
ASTM Q195 exhibits high plasticity, toughness, weldability, and good pressure processing performance. At the same time, its use is also wide, involving various industries.
A572 Galvanized steel pipe is used for automobiles, sanitary ware, food machinery, pressure vessels, nuclear power, chemical equipment, elevators, rail transit, machinery manufacturing, structural piping, and architectural decoration.
Galvanized seamless pipe has very good physical and chemical properties, its tensile strength is more than 8 times stronger than ordinary steel, and its elastic modulus is also better than ordinary steel. Moreover, it also has good mechanical capabilities and is very easy for daily processing. Long term use will not deform, anti-static ability is good.
A333 Seamless & Welded Steel Pipe
ASTM A333 is the standard specification for seamless and welded carbon and alloy steel pipe for low temperature applications or other applications requiring notch toughness. This standard covers several grades of ferritic steel: Grade 3, Grade 4, Grade 6, Grade 7, Grade...
