Carbon steel pipes are divided into two types: hot-rolled and cold-rolled (drawn) steel pipes.

Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.

In addition to general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and other steel pipes, cold-rolled (dial) carbon steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, Rust thin-walled steel pipes, special-shaped steel pipes. The outer diameter of hot-rolled seamless pipe is generally greater than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel pipe can reach 6mm, and the wall thickness can reach 0.25mm. The outer diameter of thin-walled pipe can reach 5mm, and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.

General carbon steel pipe: It is made of high-quality carbon steel such as 10, 20, 30, 35, 45, 16Mn, 5MnV and other low-alloy structural steels or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steels that are hot-rolled or cold-rolled. 10, 20 and other low carbon steel seamless pipes are mainly used for fluid conveying pipelines. Seamless tubes made of medium carbon steel such as 45 and 40Cr are used to manufacture mechanical parts, such as stressed parts of automobiles and tractors. Generally, carbon steel pipes are used to ensure strength and flattening tests. Hot-rolled steel pipes are delivered in a hot-rolled or heat-treated state; cold-rolled steel pipes are delivered in a heat-treated state.

Advantages of Seamless Steel Pipes: Unveiling the Benefits, In the  realm of steel pipes, seamless steel pipes have gained immense popularity due to their exceptional characteristics and wide range of applications.
In this article, we will delve into the advantages of seamless steel pipes, exploring their unique features, performance benefits, and the industries that benefit from their usage.
By the end, you will have a comprehensive understanding of why seamless steel pipes are a preferred choice in various sectors.
Strength and Durability:Seamless steel pipes are renowned for their superior strength and durability.

Structural Carbon Steel Application Information

As the carbon content rises, steel has the ability to become harder and stronger through heat treating, but this also makes it less ductile. In carbon steels, a higher carbon content reduces weld ability and lowers the melting point.

Carbon Steel Tube and Pipe Properties and Composition

As the carbon content rises, steel has the ability to become harder and stronger through heat treating, but this also makes it less ductile. In carbon steels, a higher carbon content reduces weld ability and lowers the melting point.

Steel is commonly considered carbon steel when no minimum content is specified for any alloying element (for example, aluminum, chromium, nickel, molybdenum, vanadium, etc.) or any other element added to obtain a desired alloy effect. The manganese does not exceed 1.65%, the specified minimum for copper in not below .40% or exceed .60% and silicon does not exceed .60%.

Carbon levels are divided as follows:

low carbon = .06% to .25% carbon content (mild steel)

medium carbon = .25% to .55% carbon content (medium steel)

high carbon = >.55% to 1.00% carbon content (hard steel)

Carbon grades are available in the following grade series:

10XX = non-resulpherized carbon steel, with manganese 1.00% maximum (for example 1018, 1045 and 1050).

11XX = resulpherized carbon steel (for example 1117, 1141 and 1144).

12XX = rephosphorized and resulpherized carbon steel (for example 12L14 and 1215)

The second two numbers in AISI-SAE designations indicate the approximate carbon content for steel (for example, in 1018 the carbon range is .15% to .20%; .18% [shown as “18”] is the approximate carbon content).
