- Seamless Steel Pipe Application In The Automotive IndustryThe seamless steel pipe is made from relatively hard raw materials, and due to the special process, there is no gap, it has been used in many industries, buildings, and many other areas, such as in the automobile industry, effectively improving the overall quality and extending the service time.Intr
- The application of welded steel tube ?1. Welded steel pipe for low-pressure fluid transportation (GB/T3092-1993) is also called general welded pipe, commonly known as black pipe. It is a welded steel pipe used for conveying general lower pressure fluids such as water, gas, air, oil and heating steam and other purposes. The thickness of
- 30 CrMo30CrMo is a kind of alloy steel. It is with high static strength, fatigue limit and impact strength. So it is be used for making sucker rod.30CrMo is middle carbon alloy steel. It has good technical and mechanical properties and the price is more competitively price. But 30CrMo performance is unstab
- Adapt to the new normal, to accelerate the supply side of the seamless steel pipe industry structural reformDuring the “Twelfth Five-Year Plan” period, the output of seamless steel pipes in China increased rapidly, reaching 60% of the world's total output. China's steel pipe industry provided Important raw materials for the national energy, construction, machinery, automobiles, home appliances, shipbuildi
- EU's influence on anti-dumping of Chinese seamless steel pipeWith the gradual improvement of the international trade organization, the world's major countries will face different opportunities and challenges, especially after China's reform and opening up, not only in the WTO in 2001, but also continuously improve China's participation in the World Trade Orga
- Why should the seamless steel pipe be pickled?In the rolling of precision seamless steel tubes, especially in the production process of precision seamless steel tubes, how did the pickling process actually proceed? Today Raymond steel tube will soon unveil this mystery for you!1. Summary of precision seamless steel pipe picklingThe method of re
- Effective Quenching Method to Avoid Deformation and Crack of Seamless Steel TubeIsotherm quenching is one of the effective quenching methods to reduce the deformation and cracking of seamless steel tubes. However, how to adopt this process correctly is to make reasonable selection according to the material, size, hardness, toughness, deformation and specific working conditions
- Residual Stress of steel tube and its harmWhen the precision seamless steel pipe is deformed because of the external factors (such as force, humidity, temperature field, etc.), the internal forces that interact with each part of the object are produced to resist the effect of the external cause, and try to restore the object from the post d
- How can the manufacturer eliminate the stress of precision steel tube?1. Natural aging elimination of residual stress Natural aging is a method to stabilize the dimensional accuracy of parts by exposing them outdoors for several months to several years. A large number of experiments and production practice have proved that natural aging has good effect in stabilizing the dimensional accuracy of castings.
- Thick wall seamless steel tubeThick-walled seamless steel pipe is a common type of thick-walled seamless steel pipe. It is a special material for thick-walled steel pipe. For thick-walled seamless steel pipe, it is more important to protect the most basic use and play. More important performance. Thick-walled seamless steel pipe
