ERW (Electric Resistance Welded) pipes and LSAW (Longitudinal Submerged Arc Welding) pipes are both common carbon steel welded pipes. However, there are significant differences in the form of raw materials, welding methods, size ranges, mechanical properties and application fields.

Carbon steel pipes, also known as CS pipes, are made from steel ingots or solid round bars. They have high strength and are widely used in various industries.

Galvanized carbon steel pipe is a type of steel pipe that uses ordinary carbon steel pipe as the base material and is coated with a layer of zinc on its surface to form a physical and chemical barrier, thereby significantly enhancing the pipe's corrosion resistance and service life.

Carbon steel square tubes are a common type of metal profile, named for their square or rectangular cross-section.

ASTM A36 is a carbon structural steel standard issued by the American Society for Testing and Materials. ASTM A36 is not specifically for steel pipes but covers carbon steel products including pipes (structural sections, plates and bars, etc.).

CENTRAL STEEL is a leading manufacturer, exporter and stockholder of carbon steel pipes in China. We have always been committed to providing high-quality steel pipes and related products for customers worldwide.

Carbon steel water pipe is one of the various types of carbon steel pipes. By applying special coatings on the inside and outside of carbon steel pipes, it meets the corrosion resistance requirements in different environments.

Low-temperature carbon steel pipes refer to carbon steel pipes specifically used in low-temperature environments (typically -50 ℃ to 0℃, or even lower).

Forged carbon steel pipe fittings are small-diameter high-pressure pipe fittings manufactured through forging processes.

Large-diameter carbon steel pipes usually refer to carbon steel pipes with an outer diameter of DN600mm (NPS 24 ") or above.

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 is a durable piping solution featuring a carbon steel body with a dense cement mortar lining. The cement lining acts as a protective barrier, preventing corrosion, scaling, and chemical damage while improving flow efficiency.

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.
