In the construction and industrial sectors, high-quality steel is a key material for withstanding mechanical loads and environmental factors, with round pipes being popular for their excellent performance. Often manufactured from carbon steel, alloy steel or cast iron, these pipes are characterized by high strength and corrosion resistance, making them suitable for a wide range of scenarios.

Core characteristics of round pipes

The most distinctive feature of round pipes is their round cross-section, which is available in a wide range of sizes (diameters of 15-100 mm and lengths of up to 7,000 mm) to meet different engineering requirements. The wall thickness (up to more than 12 mm) directly affects its load-bearing capacity and needs to be selected according to the actual application environment (e.g. temperature, pressure, etc.).

Surface treatment processes are varied and include:

Mechanical polishing: abrasives of different grit sizes are used to eliminate surface defects, and the finish can be further optimized by polishing paste.

Chemical polishing: utilizing acidic solutions to form a smooth protective layer.

Electrochemical polishing: Enhancement of surface corrosion resistance by means of an electrolytic process.

Hot-dip galvanizing: Forms a zinc layer on the surface to enhance rust resistance.

Main Application Areas

Oil & Gas: Used to transport oil and gas resources to ensure the safety and stability of media transportation.

Construction engineering: as a frame structure or support member, widely used in industrial plants, civil buildings and temporary facilities (such as pavilions, garages, etc.).

Water supply and heating system: suitable for hot and cold water pipelines and sewage treatment facilities, taking into account the needs of indoor and outdoor installation.

Chemical industry: stainless steel round pipe can withstand acid, alkali and other corrosive media, commonly used in chemical transportation.

Mechanical manufacturing and transportation: used in aviation, automotive and heavy equipment manufacturing, to meet the demand for high-strength, lightweight.

Decorative and auxiliary uses: small round tube can be used for railings, furniture and other decorative structures, both functional and aesthetic.

Round tubes have become an indispensable key material in modern industry and construction due to their excellent mechanical properties, various surface treatment technologies and wide application adaptability.
