What are the types and uses of round tubes?

Round piperefers to Steel with two ends open and hollow concentric cross-section, and its length is larger than the periphery. It can be used in pipelines, thermal equipment, mechanical engineering, petroleum geological drilling, vessels, chemical industry and special purposes.

The application of Round Tubes in different fields
1. Round pipe for structure

Structural Round Pipe is a metal material mainly used in building structures, bridges, airport runways, docks, subways and highway tunnels. In addition, structural tubes are often used in manufacturing processes such as steel frames, pianos, and springs.

2. Round pipes for machinery

Round pipes for machinery refer to pipes used in the manufacture of various mechanical equipment, such as excavators, power engineering, heavy vehicles and railway vehicles. The material of the round tube for machinery is generally low carbon steel, alloy steel and stainless steel, etc., and its technical requirements are high, and its manufacturing process is cold working and forming on the bar.

3. Round pipes for hydraulic and pneumatic pressure

Hydraulic and pneumatic tubes are commonly used to convey liquids or gases, such as compressed air, heated water, steam and nitrogen. Hydraulic and pneumatic round pipes can be made of different materials according to the requirements of the use conditions. Generally speaking, high-pressure pumps and pneumatic devices are commonly made of carbon steel pipes, alloy steel pipes, and stainless steel pipes.

4. Underground transmission pipelines

Underground transmission pipelines refer to pipelines that transport large, medium and small substances such as gas, oil, water, and electricity transmission over long distances underground. In the engineering design and construction of underground transmission pipelines, round pipes are widely used. Compared with the transmission pipeline made of other materials, steel has stronger corrosion resistance, less pavement damage, and longer service life, so it is more and more widely used.

5. Round pipes for steel and wood furniture

Round pipe for steel and wood furniture is a new type of steel pipe material for furniture, which can be used with solid wood, wood-based panels and other materials to make furniture with a very creative and design sense. Due to its personalized, customized and sustainable environmental protection characteristics, the market demand for steel and wood furniture is showing a rapid growth trend.

A common material choice for round pipes

The properties of steel are relatively good, so there are relatively many materials in the choice of manufacturing round pipes. Commonly used materials include carbon structural steel, low-alloy high-strength steel, aluminum and alloy materials, etc., and different material choices are inseparable from the matching of use scenarios.

1. Carbon structural steel

Carbon structural steel is one of the most common types of steel, which is widely used in the production of round pipes because of its cost-effective value. Under the right conditions, carbon structural steel can also guarantee a long service life and stable mechanical properties.

2. Low-alloy high-strength steel

The strength of low-alloy high-strength steel far exceeds that of traditional carbon structural steel, and it has good toughness and weldability. When used in special machinery manufacturing and bridge construction industries, steel round pipes are usually made of this type of material.

3. Aluminum and alloy materials

Aluminum and alloy materials have also become one of the commonly used materials for round pipes due to their light weight, corrosion resistance, high strength and excellent thermal conductivity. In the application of pneumatic systems, aluminum and its alloys are more widely used due to their light weight and easy maintenance.

Round tubes play a key role in a number of areas:
1. Architectural field
Structural support: In the construction of building frames, large-diameter metal round pipes often act as columns and beams, bearing the vertical and transverse loads of the building and providing stable support for the overall structure. For example, in some large-scale industrial plants and exhibition halls, high-strength steel pipe columns ensure the openness and stability of the building space, and resist wind, snow and seismic forces.
Water supply and drainage system: a large number of round pipes are used in various types of water supply and drainage pipelines, such as urban water supply main pipelines to transport residents' domestic water, and sewage discharge pipelines collect and treat domestic sewage, because of their circular cross-section water flow resistance, not easy to block, can efficiently complete the liquid transportation task, and ensure the smooth circulation of urban water.
2. Industrial manufacturing
Material Transportation: Inside the factory, the round pipe is used as a conveying pipe to transport all kinds of fluids, gases, and powdery materials. For example, in chemical enterprises, corrosion-resistant plastic round pipes or metal round pipes transport chemical raw materials such as acid and alkali; In the food processing plant, stainless steel round pipes convey liquid foods such as milk and juice to realize the automation of the production process and improve the efficiency of production.
Mechanical protection and structure: small round pipes can be used to make protective fences and handrails of machinery and equipment to ensure the safety of operators; In the structure of mechanical parts, the precision round tube is assembled into a complex mechanical structure through cutting, welding and other processes to provide correct action parts for the operation of the equipment.
3. Energy sector
Oil and gas transportation: After oil and natural gas exploitation, it needs to be transported to various places for a long time, and the oil and gas pipelines laid underground and above ground are mostly in the form of round pipes, which have the characteristics of high pressure resistance and good sealing performance, so as to ensure the stable transmission of energy, cross mountains, rivers, lakes and seas, and connect energy production areas and consumer markets.
Power transmission: Some wires and cables are also often wrapped in round pipes to insulate and protect the cables from external mechanical damage, corrosion and bad weather, and maintain a stable power supply.
4. Home life
Furniture decoration: metal and wooden round pipes are cleverly integrated into furniture design, such as steel pipes for table legs and chair legs, which are both fashionable and sturdy; Wooden round pipes can be used to decorate the borders of wardrobes and cabinets, adding a natural style and design beauty.
Horticultural landscape: In gardens and courtyards, PVC round pipes are used to build flower trellises and grape trellises, which are light and inexpensive; Metal round pipes can be made into delicate railings, dividing the landscape space and enhancing the ornamental and practical nature of the outdoor space.
