SA210C Seamless Pipe

SA210C seamless pipe follows the ASME SA-210M standard, which is a medium carbon seamless pipe designed for boilers and superheaters. It occupies an important position among many pipe materials, especially in the field of boiler tube. The following is a detailed introduction to SA210C seamless pipe:

Basic information

Standard: ASME SA-210/SA-210M

Material: High-strength carbon manganese steel

Features: High strength, high temperature resistance, high corrosion resistance and relatively simple manufacturing process

Chemical composition

The chemical composition of SA210C seamless pipe mainly includes carbon, manganese, silicon, phosphorus, sulfur and other elements, and the specific contents are as follows:

Carbon (C): ≤0.35%

Manganese (Mn): 0.29%~1.06%

Silicon (Si): ≥0.10%

Phosphorus (P): ≤0.035%

Sulfur (S): ≤0.035%

These chemical components work together to make SA210C seamless pipe have excellent mechanical properties and corrosion resistance. Compared with SA210A1, SA210C has a higher upper limit of carbon content, a wider range of manganese content, lower silicon content requirements, and higher upper limits of phosphorus and sulfur content. Good chemical composition control enables it to provide stronger adaptability when facing a variety of complex working conditions compared to ordinary carbon steel pipe.

Mechanical properties

The mechanical properties of SA210C seamless pipes are excellent, and the specific indicators are as follows:

Tensile strength: ≥485MPa

Yield strength: ≥275MPa

Elongation: ≥30%

Hardness: ≤89HRB

These mechanical properties ensure the safety and reliability of SA210C seamless pipes under high temperature and high pressure environments. In practical applications, whether they are hydraulic tubes used to withstand high pressure or heat exchanger tubes that requires high toughness, SA210C seamless pipes can meet the needs with excellent mechanical properties.

Specifications

SA210C seamless pipes have various product specifications to meet the needs of different fields. Its outer diameter range is usually 57mm762mm, and its wall thickness range is usually 3.0mm130mm. In addition, there are special specifications such as internally threaded pipes, such as SA210C internally threaded pipes with a nominal diameter of DN63.5mm (about 2.5 inches in diameter) and a wall thickness of 7.1mm.

Production process

SA210C seamless pipes have high requirements for welding performance. Generally, no preheating is required before welding, and no heat treatment is required after welding. Be careful to avoid the blue brittle temperature of about 250℃ for pipe bending. Usually, hot rolling is used for forming. This process has the advantages of high production efficiency, low cost, and high strength. At the same time, it can improve the physical properties of steel pipes, making them more suitable for high temperature and high pressure environments.

Application field

SA210C seamless pipes are widely used in many industries, including:

1. Construction industry

Used for the construction of high-rise buildings, large-span bridges, large industrial plants and other structures, especially for buildings in earthquake-prone areas.

2. Petrochemical industry

Due to its corrosion resistance and high pressure resistance, it is widely used in pipeline systems in the petroleum and chemical industries.

3. Power industry

Mainly used for manufacturing high-voltage electric poles and wire brackets, and also used for water-cooled walls, economizers, low-temperature superheaters and other heating surface pipe systems and headers, steam-water pipes, etc. of large-capacity power station boilers. In this field, SA210C seamless pipe is an ideal choice for manufacturing casing pipes and pup joints.

4. Shipbuilding industry

It can meet the high requirements of shipbuilding and is widely used in the manufacture of ship bottom structures and cabins.

5. Environmental protection industry

It is used in sewage treatment and garbage disposal systems and can withstand the erosion of various corrosive substances.

Inspection and certification

During the production process, SA210C seamless pipes need to undergo strict inspection and testing, including chemical composition analysis, mechanical properties testing, metallographic structure inspection, etc. Only steel pipes that pass all inspections can be identified as qualified products and put into market use. At the same time, the steel pipe also meets the requirements of the ASME SA-210M standard, ensuring the reliability of its quality and performance.
