Q345 is a grade of carbon structural steel. Q is the meaning of yield strength, which is taken from the first letter of the Chinese pinyin of "Qu"; 345 means the value of the yield point, and the unit is MPa. Q345 represents a carbon structural steel with a yield point (σs) of 345MPa. The letters at the back represent the quality grades, and there are five grades A, B, C, D, and E. Q345 Galvanized Steel Pipe has good comprehensive mechanical properties, acceptable low temperature performance, good plasticity and weldability, and is used for structures, mechanical parts, buildings, etc. that bear dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations, bridges, etc. Structure, general metal structural parts, used in hot-rolled or normalized state, and can be used in various structures in cold areas below -40 °C. Q345 steel Pipes can be divided into Q345A, Q345B, Q345C, Q345D, Q345E according to the grade. What they represent is mainly that the temperature of the shock is different. The Q345A grade is no impact; the Q345B grade is a 20 degree shock at room temperature; the Q345C grade is a 0 degree shock; the Q345D grade is a -20 degree shock; the Q345E grade is a -40 degree shock. At different shock temperatures, the value of shock is also different.

Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.
Galvanized Steel Pipe is a Welded Steel Pipe with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong the service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensers in chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, and pipes for trestle piles, supporting frames for mine tunnels, etc.
