High-quality carbon steel seamless pipe

High-quality carbon steel seamless pipe

What is carbon steel seamless pipe?

Carbon steel seamless steel pipe is a kind of hollow section, no joints around the strip steel. Steel pipes with hollow sections are widely used as conduits for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, It has the same bending and torsional strength and is lighter in weight. It is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.

Typical carbon steel pipe material grades in API 5L Grade B, X42 to X70, ASTM A106 B, ASTM A53 B, ASTM A252 Grade 3 and ASTM A333 Grade 6 etc.

The properties of carbon steel seamless pipe:

Carbon steel has good properties in hardness and strength, and it is less expensive than other steels. The properties of carbon steel are high hardness, strength, wear resistance and anti-corrosion.

How to choose high-quality carbon steel seamless pipes?

The performance of seamless steel pipe is very good, it has a wide range of applications. Then, It has good corrosion resistance, practicability is indeed guaranteed. In addition, the service life is also very long. Most importantly, many construction parties need to purchase steel pipes in large quantities. It is also very important to choose a reliable seamless steel pipe manufacturer for cooperation. But how to choose high-quality carbon steel seamless steel pipe?

In fact, the wall thickness of carbon steel seamless steel pipe with better quality is uniform. And the thicker the wall thickness, the more quality assurance, and the practicability is also very good, which can ensure a long service life. Therefore, when we purchase carbon steel seamless steel pipes, we still need to do a good job of testing, and we must determine the specific thickness, so that the purchased steel pipes can also meet our needs.

The seamless steel pipe manufacturer recommends that you still do a good job of comparing the physical aspects, and the surface must be smooth and have a certain luster. If there are pits, black spots, etc. on the surface, it cannot be eliminated, and it will also affect the later use. Appearance quality: There shall be no cracks, folds, folds, delaminations, hair lines and scarring defects on the inner and outer surfaces of the steel pipe. These defects should be completely removed, and the wall thickness and outer diameter should not exceed negative deviations after removal.

3. Overall inspection

If you purchase steel pipes in large quantities, you can also contact the seamless steel pipe manufacturer and send certain samples for later testing. Generally, it can guarantee a good use effect under high pressure and high strength environment, and a simple test can also select high-quality seamless steel pipe.
