A106 Gr.C Seamless Steel Pipe

A106C seamless steel pipe is a kind of high-pressure boiler pipe, which is mainly used in the water wall, superheater, preheating zone, heat exchanger, pipeline and other parts of the boiler. The working pressure is 6MPa~13.9MPa, and the steam temperature is 450~580℃ , belonging to the high-pressure vessel. A106C is mostly thick-walled boiler tubes, and the working conditions are harsh, so A106C finished pipes are required to have good plasticity and toughness, low sensitivity to actual effects; good welding performance and cold bending performance; high room temperature and Medium temperature strength.

Product Features

 

High-temperature Resistant
This pipe can stably transport steam or hot media in environments ranging from -29°C to 425°C, preventing deformation or leakage caused by high temperatures.

 

Precision Machining
The pipe's outer diameter tolerance is controlled to ±0.2mm, and its wall thickness is uniform, ensuring tight fitting joints and facilitating on-site installation and welding.

 

Customization Capabilities
A106 Gr.C seamless steel pipe can be customized based on outer diameter, wall thickness, length, and steel composition.

 

Product Application

 

Oil Transportation
A106 Gr.C seamless steel pipe is primarily used for transporting crude oil and refined oil products.

 

Natural Gas Pipeline
A106 Gr.C seamless steel pipe is suitable for long-distance, high-pressure natural gas transportation.

 

High-Temperature Steam Pipeline
This steel pipe is used for transporting high-temperature steam in boilers and thermal power plants.

 

Chemical Pipeline

FAQ

Q: What is A106 Gr.C Seamless Steel Pipe used for?

A: A106 Gr.C seamless steel pipe is commonly used in high-temperature and high-pressure applications, such as oil and gas refineries, power plants, petrochemical plants, and boiler systems, where consistent mechanical performance under elevated conditions is critical.

Q: What are the standard size ranges for A106 Gr.C pipes?

A: A106 Gr.C seamless pipes typically come in NPS 1/8" to 48", with wall thicknesses as per SCH10 to SCH160 or XXS, and custom lengths are available depending on client requirements.

Q: How is A106 Gr.C different from A106 Grade B?

A: The key difference lies in strength: Grade C has higher carbon content and higher tensile/yield strength than Grade B. Therefore, A106 Gr.C is chosen for more demanding pressure systems, while Grade B is more common in standard industrial piping.
