The performance of seamless steel pipe is very good, and it has a wide range of applications, and has good corrosion resistance, practicability is indeed guaranteed, and the service life is also very long. Moreover, 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?
1. Pay attention to the wall thickness
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.
2. Steel pipe surface inspection
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.
4. Both ends of the steel pipe should be cut at right angles and burrs should be removed. Steel pipes with a wall thickness greater than 20mm are allowed to be cut by gas cutting and thermal sawing. After the agreement between the supply and demand sides, the head may not be cut.
