In order to improve the service life of oil well pipes and reduce costs, oil fields require oil well pipes to be used repeatedly, which puts forward good anti-galling performance requirements for oil pipes. Because if the tubing is glued, the integrity of the threaded connection will be destroyed, and continued use may lead to leakage at the threaded connection, reduced connection strength, and serious accidents such as falling off the well may occur, causing huge economic losses to the oil field.
In recent years, experts from various countries have developed various new coatings for the phenomenon of oil casing thread gluing. At present, the main ways of thread surface treatment can not meet the requirements of good anti-galling performance, environmental protection, low cost and easy operation. Therefore, it is of great industrial value to develop a new type of anti-wear and anti-friction coating with excellent anti-thread galling performance, simple treatment, high reliability, energy saving and low price.
Recently, an enterprise in China has successfully realized the large-scale mass production of super special buckle coupling. This buckle coupling has attracted wide attention for its unique design and excellent performance.
When performing flaw detection, it is necessary to select the appropriate flaw detection method according to the specific situation, and operate in strict accordance with relevant standards and requirements to ensure the quality and safety of the coupling material.
