Hot dip galvanized seamless steel pipe

Hot-dip galvanizing (galvanizing) is also called hot-dip galvanizing and hot-dip galvanizing: it is an effective way to prevent metal corrosion, mainly used in metal structural facilities in various industries. It is to immerse the rust-removed steel parts in a zinc solution melted at about 500°C, so that the zinc layer adheres to the surface of the steel components, thereby achieving the purpose of corrosion protection.

Galvanized Pipe VS Seamless Steel Pipe

Galvanized pipe and seamless steel pipe are two areas of steel pipe. Galvanized refers to the surface of the steel pipe being galvanized. It may be a welded pipe or a seamless pipe. Galvanized pipes are more corrosion-resistant, and seamless steel pipes can withstand greater pressure. Galvanized steel pipes are not easy to rust because of the protection of zinc. The difference between galvanized steel pipes and seamless steel pipes can be understood as galvanized seamless steel pipes and seamless steel pipes. Galvanized steel pipes refer to steel pipes with a layer of zinc applied to the surface of ordinary steel pipes. The zinc layer can form a protective film on the surface of the steel pipe, which can effectively extend the service life of the steel pipe and improve the corrosion resistance of the steel pipe. Galvanized steel pipes are divided into hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing has a thick galvanized layer, which has the advantages of uniform coating, strong adhesion and long service life. Electro-galvanizing has low cost, but the surface is not very smooth, and its own corrosion resistance is much worse than that of hot-dip galvanized pipes. Seamless steel pipes are made of a whole piece of metal, and steel pipes without seams on the surface are called seamless steel pipes.

Carbon Steel Casing Pipe

Carbon steel casing pipe is a key component used in oil wells. Its main function is to establish a pressure-resistant and sealed channel from the oil and gas reservoir to the ground. It is not only used to protect the drill string and oil pipe in the oil well, but also to prevent the well wall from collapsing and ensure the smooth progress of the drilling process. In the oil and gas extraction industry, carbon steel casing pipe, together with oil pipe and drill pipe, is collectively referred to as oil country tubular goods, abbreviated as OCTG (Oil Country Tubular Goods). These pipes are widely used in oil and gas extraction due to their high strength, pressure resistance and corrosion resistance.

Seamless steel pipe pickling and passivation process

In the production process of seamless steel pipe, pickling and passivation process is one of the key links. It can not only improve the surface quality of steel pipe, but also enhance the corrosion resistance of steel pipe and extend its service life. As an important material in industrial production, precision seamless steel pipe is widely used in petroleum, chemical, boiler, power station, machinery and other industries due to its high precision, high strength and good corrosion resistance. In these fields, the surface quality of seamless steel pipe directly affects its subsequent service life and performance. Therefore, it is particularly important to pickle and passivate the surface of steel pipe during the production process.

Black Steel Pipe VS Carbon Steel Pipe

The carbon content in steel determines its properties. Steel is considered carbon steel when no minimum content of chromium, cobalt, niobium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium or any other element added to obtain the desired alloying effect is specified or required; when the minimum copper specified does not exceed {{0}}.4%; or when the maximum content of any of the following elements does not exceed the percentage noted: manganese 1.65%, silicon 0.6%, copper 0.6%. Most of the steel produced worldwide is carbon steel.
