How to use a double centralizer
The primary benefit of a double centralizer is stabilizing the azimuth. In practice, we've found that in most cases, dual centralizers stabilize and slightly increase azimuth. Some drill string configurations often exhibit a strong azimuth increase,
Study on Heat Treatment Technology of X80 Seamless Steel Pipe
Pipelines are essential for transporting oil, natural gas, and even solid materials like coal over long distances. As global energy demands grow, high-pressure, long-distance transmission pipelines have become vital for large-scale natural gas delivery. This
How to determine the post-weld heat treatment temperature of T/P91 alloy steel?
T/P91 alloy steel is widely used in high-temperature and high-pressure piping systems, especially in power and petrochemical industries. While its welding and heat treatment processes are well-documented, there remains some confusion and inconsistency in practical
