Carbon steel rectangular tubes are rectangular hollow cross-section profiles made of carbon steel. Carbon steel is a widely used alloy, renowned for its strength and durability.

Pipe fittings are usually components used to connect pipes or various parts of pipe systems. They play a crucial role in the pipeline system.

Carbon steel welded pipe fittings are connection parts made of carbon steel as the base material through welding methods such as butt welding and socket welding, and are widely used in fields such as petrochemicals, chemical engineering, power, water treatment and HVAC.

Thick-walled carbon steel pipes are a type of carbon steel pipe with relatively large wall thickness, widely used in fields such as oil and gas transportation, high-temperature and high-pressure equipment, structural support, and industrial fluid transportation.

Carbon steel pipes are steel pipes with carbon as the main alloy component, widely used in the transportation of industrial fluids, especially playing a dominant role in natural gas and oil pipeline systems.

Carbon steel pipe fittings (CSFT) are pipe connection components made mainly of carbon steel through processes such as smelting, forming, processing, welding and surface treatment.

Coated carbon steel pipes enhance the corrosion resistance and service life of carbon steel pipes by applying a composite coating on the outer wall, inner wall or both of the pipes.

Schedule (Pipeline grade) represents the wall thickness series of the pipeline and is defined in accordance with the ASME B36.10M (carbon steel and alloy steel pipes) and B36.19M (stainless steel pipes) standards. Under the same nominal diameter (NPS), the Schedule 80 (also known as Extra Heavy, XS) pipe has a thicker wall thickness than the Schedule 40 (STD) pipe, resulting in a reduction in the inner diameter but maintaining the same outer diameter.

Carbon steel round pipes are circular cross-section pipes mainly made of carbon steel and may contain small amounts of elements such as manganese and silicon.

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.).
