Carbon Steel Pipe/Tube is a tubular product made of carbon steel as the main material, which is widely used in many industries such as construction, machinery, oil and gas, chemical industry, electricity, water supply, aviation, etc. The main advantages of carbon steel pipe are high strength, strong durability, good weldability, processability and economy. According to different application requirements, carbon steel pipe can be made by different processing techniques, such as hot rolling, cold rolling, welding and seamless.
Material and classification
Carbon steel pipe is usually made of carbon steel, which can be divided into low carbon steel, medium carbon steel and high carbon steel according to the carbon content. Each type of carbon steel pipe differs in strength, hardness and toughness, and is suitable for different applications.
Low carbon steel pipe (carbon content ≤0.25%):
Mainly used for pipes with lower pressure, such as HVAC systems, low-pressure transmission pipelines, building structures, etc.
Medium carbon steel pipe (carbon content 0.25%-0.60%):
Suitable for applications requiring higher strength and toughness, such as machinery manufacturing, automobiles, ships and other fields
High carbon steel pipe (carbon content>0.60%):
used for pipes that withstand high pressure or require high hardness and wear resistance, such as tool pipes, spring steel pipes, etc.
Specifications of carbon steel pipes
The specifications of carbon steel pipes mainly include outer diameter, wall thickness, length and shape of steel pipes. Common specifications are:
Outer diameter (OD): The outer diameter of carbon steel pipes ranges from 6mm to more than 1000mm, which can be customized according to needs.
Wall thickness (WT): The wall thickness of carbon steel pipes is generally between 1mm and 100mm, which is selected according to the pressure and purpose of the pipe.
Length: Common lengths are 6 meters and 12 meters, which can also be customized according to customer needs.
Material standards: Common material standards include ASTM A106, ASTM A53, API 5L, etc. The specific material is determined according to the application environment and technical requirements of the pipeline.
