Hot dipped galv.seamless steel pipe is a steel pipe coated with a layer of zinc on the surface. The molten metal reacts with the substrate to form an alloy layer, so that the coating and the substrate are firmly bonded, and the thickness of the coating is uniform. It also has good corrosion resistance due to its galvanized coating.

Black steel pipes are a type of steel tubing that are commonly used in a variety of applications across different industries. They are known for their durability, strength, and resistance to corrosion, which makes them an ideal choice for many different types of projects.

Steel pipes are cylindrical tubes made from steel that are used many ways in manufacturing and infrastructure. They’re the most utilized product made by the the steel industry. The primary use of pipe is in the transport of liquid or gas underground—including oil, gas, and water. However, pipes of varying sizes are used throughout manufacturing and construction.

Hot dip galvanized tubes are steel pipes obtained by hot-dip galvanizing on the surface of the steel pipe. Hot dip galvanizing is the process of coating iron, steel or ferrous metal with a layer of zinc.

The hot-dip galvanized steel pipes have uniform coatings of hot-dip galvanizing, and the hot-dip galvanizing has strong adhesion and long service life. So the hot-dip galvanized steel pipes have strong corrosion resistance.
