What does carbon seamless steel pipe mean What is the difference between it and ordinary 20 seamless

Seamless is a kind of carbon steel, which belongs to low carbon steel and is a commonly used steel pipe, due to the low carbon equivalent, the weldability is better.

Belonging to its category, Liaocheng Xinyi Machinery in Shandong Province is mainly engaged in all kinds of seamless steel pipes, Liaocheng Xinyi, a large company, trustworthy.

Generally, it refers to seamless steel pipes with carbon content as the main focus. 20 and so on are counted in carbon seamless steel pipes. Hope it helps.

Carbon steel is relative to alloy steel, and its carbon content is higher than that of alloy steel, and 20 steel is a type of carbon steel.

It belongs to carbon steel, which is distinguished by carbon content.

Carbon steel is actually relative to alloy steel, its main thing is that it has a high carbon content, and 20 seamless steel is carbon steel! In addition, there is stainless steel, stainless steel is also a kind of alloy steel, but the processing technology is different, the performance is not the same, and it looks good on the outside!

The description of the material in alloy steel is actually the content of each metal element in the steel (usually a percentage number).

Generally speaking, steel grades are divided into two categories according to chemical composition: carbon steel and alloy steel;

1) Carbon steel: low carbon steel (C; Medium carbon steel (; High Carbon Steel (C 2) Alloy Steel: Low Alloy Steel (Alloy 5%); Medium alloy steel (5% alloy 10%); High-alloy steel (alloy 10%)

Carbon seamless steel pipes are mostly pipes for mechanical engineering structures and pipes for transporting fluids.

The D of seamless steel pipe D325 8 stands for diameter, that is, the diameter, 325 represents the diameter is 325mm, and 8 represents the wall thickness of 8mm. In other words, the diameter of the seamless steel pipe is 325mm, and the wall thickness is 8mm.

Seamless steel pipe is made of perforated whole round steel, and there is no weld on the surface, which is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, pipe jacking, etc.

According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special-shaped, and special-shaped pipes have a variety of complex shapes: square, oval, triangular, hexagonal, melon-seed-shaped, star-shaped, and finned tubes. The maximum diameter is 900 mm, and the minimum diameter is 4 mm.

Depending on the application, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used for petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors and aviation.

Seamless steel pipes have a hollow cross-section, and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round bar, steel pipe has the same bending and torsional strength, and is lighter in weight, which is an economical cross-section steel.

Seamless fluorescent pipes are expressed in terms of outer diameter x wall thickness in millimeters.

D325x8 is a seamless steel tube with a diameter of 325 mm and a wall thickness of 8 mm.

Diameter 325 mm, wall thickness 8 mm.

Shanxi Lianzhong Steel Pipe helps you answer: the outer diameter is 325mm, and the wall thickness is 8mm

The outer diameter of the steel pipe is 325mm, and the wall thickness is 8mm

Carbon steel pipe and seamless steel pipe are two different types of steel pipes, and the main differences between them are as follows:

1.Manufacturing process: Carbon steel pipes can be manufactured by welding, hot rolling, cold rolling and other processes. Seamless steel pipes, on the other hand, are manufactured by solid perforation or hot-rolled, cold-rolled and other processes, without welded joints.

2.Welded joints: Carbon steel pipes produce welded joints during the manufacturing process, while seamless steel pipes do not have welded joints. Welded joints may affect the strength and sealing performance of the tube.

3.The internal and external surface of the file quality: the internal and external surfaces of the seamless steel pipe are smooth, there are no welding marks, and it has a high surface quality. The welded joints of carbon steel pipes may have defects such as welding nodules and porosity.

4.Strength performance: Since seamless steel pipes have no welded joints, their strength and toughness are usually better than carbon steel pipes.

5.Dimensional accuracy: The dimensional accuracy of seamless steel pipes is high, and the products produced meet the specified size range, while the dimensional accuracy of carbon steel pipes is relatively low.

Depending on the specific use scenario and needs, selecting the right type of steel pipe can help ensure product quality and performance requirements.

No. 20 steel is a mild steel material. Mild steel (mildsteel) is carbon steel with lower carbon content, which is also known as mild steel because of its low strength, low hardness and softness. It includes most of the ordinary carbon structural steel and some high-quality carbon structural steel, most of which are used for engineering structural parts without heat treatment, and some are used for mechanical parts requiring wear resistance after carburizing and other heat treatments.

The annealed structure of low-carbon nano steel is ferrite and a small amount of pearlite, which has low strength and hardness, and good plasticity and toughness. Therefore, its cold formability is good, and it can be cold formed by crimping, bending, stamping and other methods. No. 20 cavity repentance steel is a mild steel.

No. 20 steel carbon content, is a low-carbon structural steel, iron-carbon alloy structure, low hardness, low degree, this material on the market profiles, pipes, such as: angle steel, channel steel, flat steel, seamless steel pipes, etc., should be stored indoors, more easy to rust.

The 20 of No. 20 steel refers to the carbon content and belongs to low-carbon steel. Steel can be divided into low-carbon steel, medium-carbon orange steel and high-carbon steel. Carbon content: low carbon steel is generally less than; Medium carbon steel is generally between the bridge sparrows; High-carbon steels are generally greater than.
