Maintenance and use of drill pipe
Abstract: Drill pipe damage primarily manifests as grooves and scratches on the joint shoulder, as well as corrosion and erosion of the pipe body. This article analyzes the causes of drill pipe damage and maintenance methods during drilling operations, aiming to provide guidance for drilling operations, extend the service life of drill pipe, and prevent
Sharing some issues on post-weld heat treatment of pipelines
Post-weld heat treatment (PWHT) of pipelines usually refers to heat treatment below the metal's phase transition point, which is also commonly referred to as stress relief. The main functions of post-weld heat treatment are to release residual stress, reduce diffusible hydrogen, and improve microstructure and properties. In addition, post-weld heat treatment (PWHT) has other functions
Comprehensive Guide to Oil Pipe Cleaning Methods and Advanced Techniques
Currently, commonly used methods for cleaning oil pipes can be divided into two main categories: physical cleaning and chemical cleaning. These primarily include hot boiling cleaning, heating cleaning, laser cleaning, biological cleaning, ultrasonic cleaning, dry ice cleaning, and water jet cleaning. Below are several cleaning methods: Heating Cleaning The substances adhering to the surface
Enhancing Quality in Large Tube Sheet Forgings
Large free forging equipment is a hallmark of a country's industrial development level, and the large forgings produced play a vital role in national economic construction, defense equipment, and central installations in modern cutting-edge science. As various industries gradually shift towards larger and higher-standard equipment manufacturing, the internal quality requirements for large forgings are also
Analysis and Solutions for Downhole Stabilizer Breakage in Well Ga-E33P, Graf Project
Stabilizers are standard downhole tools in drilling assemblies. Complex downhole situations and accidents related to them often occur during drilling. Despite extensive analysis and improvements by researchers and manufacturers, the problems have not been completely resolved. The Graf project is located in southern Iraq, where multiple wells have experienced downhole stabilizer breakage during operations.
Automated Coating Processes for Seamless Steel Pipes
The commonly used automated coating processes for seamless steel pipes, such as oil casing pipes, include the following four methods: Process One Utilizes a spray coating method with linear conveyor systems, applying the coating before, after, and between the rollers to form a coating film. The pipes are then transferred using forklifts and conveyed by
Comprehensive Guide to H2S Corrosion and Corrosion-Resistant Pipe Materials in the Petrochemical Industry
In the petrochemical industry, hydrogen sulfide (H2S) corrosion is a widespread and highly hazardous phenomenon. By analyzing the corrosion mechanism of H2S, this blog introduces various forms of corrosion caused by wet H2S, including hydrogen embrittlement, hydrogen-induced cracking, sulfide stress corrosion cracking, and stress-induced hydrogen cracking. These types of corrosion are closely related to
