Welded steel pipes for oil and gas transportation refer to welded steel pipes used for transporting oil, natural gas, and their products. This type of steel pipe is formed by rolling steel plates or steel strips into a tube through a welding process. Welded steel pipes are mainly divided into straight...

Boiler tubes are a critical component of any boiler system, responsible for carrying hot gases and steam throughout the unit. These tubes play a crucial role in ensuring the efficiency and safety of the boiler, making them an essential investment for any industrial or commercial facility. By choosing high-quality...

Boiler tubes are a critical component of any industrial boiler system, serving as the conduit for transferring heat from the combustion chamber to the water that circulates within the boiler. These tubes are typically made of high-quality steel or other heat-resistant materials to withstand the extreme temperatures and...

High-pressure natural gas pipelines High-pressure natural gas pipelines have become an integral part of our modern society, providing a reliable and efficient means of transporting this valuable resource. These pipelines are designed to withstand immense pressure, ensuring the safe and efficient delivery of natural gas...

Seamless steel pipes have played a crucial role in various industries for centuries. These pipes are manufactured without any welding or joints, making them highly durable and reliable. The seamless design ensures that there are no weak points or potential leakage areas, making them ideal for transporting fluids and gases...

Steel pipes have been a crucial component in the development of modern infrastructure. Dating back to ancient times, humans have recognized the importance of channeling fluids and gases efficiently and safely. However, it was not until the 19th century that steel pipes emerged as a game-changer in this field. The invention...

3. Electron microscope analysis After the cross-section of the sample was polished, it was scanned by a QUANTA400 electron microscope. Only Si, Mn, and O elements were found on the metal substrate at the extension of the micro-cracks around the warped skin interlayer, and no continuous casting mold slag components such...

Abstract: Through the electron microscope scanning analysis of the warped skin of steel pipes, the possibility of the quality problem of the billet due to improper protection pouring in the continuous casting process of the billet was ruled out; through the analysis of the metallographic structure, combined with the basic...

Manufacturing methods of seamless steel tubes include manufacturing methods of steel smelting, tube billet and steel pipe. The technical requirements directly affect the performance and quality of the seamless steel pipe.   1.2.1 The smelting method of steel The smelting of steel is generally carried out with equipment...

A large number of seamless steel pipes of various specifications and materials are used in pipelines, valve chambers, station process pipelines, pressure vessels and pressure pipeline equipment in natural gas gathering and transportation pipeline projects, including gas gathering pipeline projects and gas transmission...
