Designing structural dimensions 1.1 Design method Among the standard pipe fittings, the tee is the most difficult to process. The structure of the tee destroys the continuity and integrity of the shell due to the opening of the hole. Under the action of external loads (mainly internal pressure), partial...

Abstract: The magnetic particle inspection for pipes and pipe fittings with various specifications and anti-corrosion coatings with different thicknesses is introduced in the construction of coal chemical engineering projects. In a methanol-to-olefins project, there are magnetic pipes and pipe fittings...

The selection of the material The material of pipe fittings should be the same or similar to that of the connected pipe. The design temperature of the pipe fittings of the China-Russia East Station is -45°C. At present, there are no standards for high-impact carbon steel and low-alloy steel...

The China-Russia East Natural Gas Pipeline Project is a major project for CNPC to build China's four major energy transportation channels. The starting point of the China-Russia East Pipeline is located in Heihe City which is at the border between China and Russia, passing through 9 provinces, including...

Compared with fossil fuels such as coal and petroleum, natural gas has high combustion efficiency in the combustion process, and the combustion products have no skin residue, and harmful gases, which is regarded as clean low-carbon energy. As the main representative of clean energy in China, ensuring...

The demand for bends is increasing and more demands on the efficiency and stability of the media transported by the bends are put forward due to the current development of product design in the direction of miniaturization, light weights, precision, and intelligence. People's research on the quality...

1.3.1 The forming process of the bend Pipe bends are formed by bending the pipe at a certain angle through various machining methods. Compared with the welded bend, the integrally formed bend has no welding seam, and the overall reliability and strength are significantly improved. In addition, when...

1.1 Introduction With the rapid development of the equipment manufacturing industry, not only technological innovation is required, but also higher requirements are put forward for the size, shape, properties of materials, and quality of surfaces. As the lifeline of equipment, pipeline systems can improve...

If the formed part fails to achieve the specified target function, that means failure, which is mainly caused by the size and shape of the product failing to meet the requirements or the change of the material structure and properties before and after forming. Some failures are beneficial, for example,...

After the persistent efforts of domestic and foreign researchers, the high-pressure forming technology of pipes has a relatively mature process method and a rich research experience. The basic research of this technology has applied to various fields, and it has a long-term research prospect for high...
