Carbon steel welded pipes are pipes made from carbon steel (mainly composed of iron and carbon, with a carbon content typically ranging from 0.06% to 1.5%) through welding processes.

Ceramic lined carbon steel pipe is a kind of composite pipe that combines the mechanical properties of carbon steel with the excellent wear resistance and corrosion resistance of ceramics, and is widely used in harsh working conditions.

Cement lined carbon steel pipe refers to the coating or centrifugal pouring of a layer of cement mortar inside the carbon steel matrix (such as standard pipes like ASTM A53, A106 or API 5L, etc.), and the formation of a protective layer after curing and solidification.

Carbon Steel PTFE Lined Pipe is a composite pipe, is a PTFE lined pipe product on the inner wall of carbon steel pipe, it combines the structural strength of carbon steel and the excellent chemical stability of PTFE, widely used in the field of corrosive media transportation.

Carbon steel pipe grades are classified according to the chemical composition, mechanical properties (such as yield strength, tensile strength) and use of the material.

Black carbon steel pipe is a common carbon steel pipe in engineering, usually refers to ordinary carbon steel pipe without coating or other surface anti-corrosion treatment.

Carbon steel pipes are one of the most common types of chilled water pipes.

Carbon steel pipes have a wide range of diameters to meet different industrial needs.

Carbon steel casing refers to the oil well casing made of carbon steel material, which is used to protect the wellbore formed during drilling, isolate different formations, and prevent downhole fluid from invading the well.

Alloy steel pipe refers to the steel pipe made by adding one or more alloy metals (such as chromium, nickel, molybdenum, vanadium, titanium, etc.) to the carbon steel substrate. The addition of these alloying elements can effectively improve the mechanical and chemical properties of steel.

ASTM A179 Carbon steel pipe is a carbon steel pipe manufactured according to ASTM A179 standard.

ASTM A53 B ERW carbon steel pipe is a resistance welded carbon steel pipe manufactured according to ASTM A53 standard, mainly used in the pipeline system to withstand general pressure and transport media.

API 5L GR.B Carbon steel pipe is an American Petroleum Institute (API)5L carbon steel pipe.

Electric fusion welding refers to a kind of electron beam welding, which uses the directional impact kinetic energy of the high-speed electron beam to convert into heating of the workpiece, so that the workpiece leaves the melt and forms a weld.

Carbon steel mechanical pipe refers to a tubular product made of low carbon or low carbon alloy carbon steel as raw material through cold working process.
