The cross section of the round tube is circular, the pressure distribution is uniform, and it has good pressure resistance. The round tube is electroplated or hot-dip galvanized, which can effectively prevent the corrosion of the pipe and extend the service life. The round tube has a regular shape, a smooth inner cavity without burrs, and can smoothly transport liquids, gases, solids and other substances.
Black round tubes generally have higher strength and can withstand greater pressure and weight. For example, when used as a load-bearing structure in the construction field, they can stably support the weight of the building; when transporting high-pressure fluids in the industrial field, they can also withstand internal pressure without damage.
A500 Grade B/C/D round pipe/tube has become an indispensable part of industrial production with its excellent material properties, diverse size specifications and surface treatment, as well as a wide range of applications.
In the fields of industry and construction, different types of steel are widely used due to their unique properties and uses. S235JB, S275JB, S355JB and S355JO are several common European standard low-alloy high-strength structural steels, which are particularly widely used in round tubes.
Q235B is a carbon structural steel with a chemical composition of carbon (C) ≤ 0.22%, manganese (Mn) ≤ 1.4%, silicon (Si) ≤ 0.35%, etc. Q355B is a low alloy steel, and the implementation standards vary depending on the material.
