The performance of the
seamless pipe (smls pipe) is very good, and it has a wide range of applications, and has good corrosion resistance. The practicability is indeed guaranteed, and the service life is also very long. Moreover, many construction parties need to purchase steel pipes in large quantities, so it is also very important to choose a reliable seamless steel pipe manufacturer for cooperation. But how to choose high-quality seamless steel pipes?
1. Pay attention to the wall thickness
In fact, the wall thickness of better-quality seamless steel pipes is uniform, and the thicker the wall thickness, the better the quality assurance. It is also very practical in terms of practicability, and can guarantee a long-term service life. Therefore, when we purchase seamless steel pipes, we still need to do a good job of testing, and we must determine its specific thickness, so that the purchased steel pipes can also meet our needs.
2. Steel pipe surface inspection
When purchasing seamless steel pipes, it is necessary to observe whether there are cracks, scars, etc. on the surface of the steel pipes. If there are pits and black spots on the surface, they cannot be eliminated, and it will also affect the later use.
Appearance quality requirements: The inner and outer surfaces of steel pipes must not have cracks, folds, rolling folds, separation layers, hairlines and scarring defects. These defects should be completely removed, and the wall thickness and outer diameter must not exceed the negative deviation after removal.
3. Overall detection
If you purchase steel pipes in large quantities, you can also contact the seamless steel pipe manufacturer to send certain samples for preliminary testing. Generally, it can guarantee a good use effect under high-pressure and high-strength environments, and high-quality seamless steel pipes can also be selected through simple tests.
4. Other precautions
a. Observe the marks and specifications on the steel pipe, as well as the name of the factory and related information.
b. Look at the quality certificate provided by the seamless steel pipe manufacturer.
c. Observe whether the paint on the surface of the seamless steel pipe is uniform, which can tell whether a company's employees are responsible for their work.
d. In order to avoid purchasing inferior products, we try our best to purchase from large well-known brand enterprises.
If you want to buy
carbon steel pipes in bulk, it is best to find the other manufacturer directly. After all, you can still enjoy certain discounts without intermediate links, and you can save more costs.
