The main steam pipe is an important part of the boiler steam and water system, and its stress is complicated at the tee and its connecting part, which is the weak part of the main steam pipe. A certain power plant has been operating for 8×104 hours. Cracks were found at the tee of the...

A pipeline, as an economical, effective, and environmentally friendly transportation method, is currently mostly used for the transportation of liquids and gases. However, leakages often occur in real life. The leakage of the pipeline may be caused by the selection and use of flanges or...

2.2.2 Testing and analysis of metallographic structure of sampled pipe caps Three samples were taken, two of which had fractures. The cross-sections of the samples were pre-ground, finely ground, ground and polished with water sandpaper and metallographic sandpaper, and etched with a 4% nitric...

Abstract: The failure of pipe caps of high-pressure steam pipelines caused by cracking was analyzed and checked. After the macro inspection of the whole, inner and outer walls, the fracture, and the microscopic metallographic structure and hardness test, the brittle failure caused by ultra-low...

Manufacturing of bends At present, there are two common manufacturing processes for bends in the world. One is hot push and the other is hot bending. If you want to make a bend with a small nominal diameter, the hot push process is generally used, while the hot bending process is...

The elbow is a common component in the piping system, and its main function is to change the direction of the pipe. Therefore, the elbow plays an important role in pipeline construction. There are many kinds of elbows, such as stainless steel elbows, alloy steel elbows and cast iron elbows. According...

There are many dos and don'ts for installing the elbow. Because the elbow is directly connected with the straight pipe, leakage will occur if you are not careful enough to install the pipe elbow. What should you pay attention to during the installation of the elbow? 1. Keep the...

1. The thin-walled stainless steel press fitting should be handled with care, and should not be thrown or trampled during construction. 2. Stainless steel press fittings should be placed away from direct sunlight.   3. When stainless steel press fittings have oil stains,...

As the name describes, stainless steel pipe fittings are made from stainless steel. They include stainless steel elbows, tees, crosses, reducers and pipe caps. According to the connection, they can be divided into four types: stainless steel socket fittings, stainless...

Reducing elbow materials are the core of new materials and play an important role in promoting and supporting the development of high tech. In the field of research of global new materials, wear-resistant materials account for about 85%. The material of the high-pressure elbow is special, and the...
