Carbon steel pipe material and classification

Carbon steel pipe (CS pipe) is a durable material made of carbon steel, a steel alloy of iron and carbon in which the carbon content is less than 2 percent steel. Carbon steel can be further divided into low carbon steel, medium carbon steel and high carbon steel, mainly depending on the carbon content in the steel. Due to its strength and ability to withstand pressure, carbon steel pipes are used in a variety of heavy industries such as infrastructure, ships, stills, and fertilizer equipment.

Advantages of carbon steel pipes:

Carbon steel piping provides safety and durability. It is an ideal material for structural applications due to its impact resistance and its imperceptibility to harsh environmental conditions such as stress or extreme weather.
 
The incredible strength of carbon steel means that carbon steel pipes can be made thinner and use less material while still being able to transport large volumes. This makes carbon steel piping a cost-effective material. Not only can the use be reduced, but the carbon steel can also be recycled, which is environmentally friendly and economical.
 

Carbon steel pipe is a versatile material due to its ease of fabrication. We can produce products in various thicknesses and sizes. It's also easy to cut and bend to fit wherever needed. It also connects easily to fittings, valves and other plumbing fittings.

Classification of carbon steel:

Mild steel (also known as light steel): 

The carbon content is usually between 0.04% and 0.30%. Low carbon steel has good ductility and toughness, can be processed hot and cold, and is easy to weld. Commonly used low carbon steels include Q195, Q215, Q235, etc.

Medium carbon steel: 

The carbon content is usually between 0.30% and 0.60%. Medium carbon steel has high strength and hardness, but low ductility and toughness. Commonly used medium carbon steels include 45# steel, 40Cr and so on.

High Carbon Steel: 

The carbon content is usually between 0.60% and 2.00%. High carbon steel has high strength and hardness, but low ductility and toughness, and poor weldability. Commonly used high carbon steels include 65Mn, T8, T10, etc.

Carbon steel pipes can be divided into seamless pipes and welded steel pipes according to the production method. Seamless steel pipes are made by hot rolling or cold drawing, and have high strength and tightness. Welded steel pipe is made by rolling steel plate or steel strip into a cylindrical shape, and then connecting the weld seams by resistance welding, submerged arc welding and other methods.

Application fields of carbon steel pipe:

Carbon steel pipe has good corrosion resistance, pressure bearing capacity and machinability, and is widely used in many fields.

1. Oil and natural gas industry: Carbon steel pipe is an important pipeline material for transporting oil and natural gas, with high strength, reliability and corrosion resistance.
2. Construction and structural engineering: Carbon steel pipes are used in construction and structural engineering, such as bridges, high-rise buildings, roads and tunnels, etc., to support and transmit loads.
3. Automobile manufacturing industry: Carbon steel pipes are used in exhaust pipes, frame and chassis and other components in the automobile manufacturing industry, and have good wear resistance and strength.
4. Mechanical engineering: Carbon steel pipes are used in conveying systems, pressure vessels, hydraulic systems and other components in mechanical engineering, and have pressure bearing capacity and reliability.

5. Chemical industry: Carbon steel pipes are used in the chemical industry for conveying systems, reactors, storage tanks and other components, with corrosion resistance and high temperature resistance.
