A valve is an important device on the oxygen pipeline and it is also a frequent source of accidents. Therefore, the selection of the oxygen valve should be very careful. The dedication...

1. Selection of elbows, reducers and tees on oxygen pipelines The elbows, reducers, and tees on the oxygen pipeline are parts that are prone to oxygen flow impact and severe friction. Some impact...

The material selection of the oxygen pipeline is a vital safety factor. As the working pressure and flow rate of oxygen pipelines increase, the pipeline's materials have also developed...

Combustion and explosion of oxygen pipelines happens frequently, resulting in great losses and many lessons learned. Two more typical explosions of oxygen pipelines occurred in 2008,...

1. The history of ductile iron pipes In 1947, H. Morrogh from the UK discovered that when cerium was added to hypereutectic gray cast iron, the graphite would be spherical with the content above...

4. The calculation of the water hammer protection 4.1 Check valves A check valve is a valve that automatically opens and closes the valve disc by relying on the flow of the medium itself...

Abstract: In the long-distance pressure sewage pipeline project, the water hammer protection measures play a vital role in ensuring the safe and stable operation of the pipeline. A sewage pipeline...

Seamless steel pipes are widely used in automobile, national defense, aerospace, machinery, shipbuilding and other fields. In recent years, with the improvement of China's scientific and...

Abstract: After a high-pressure boiler has been in service for 6 years, its seamless steel pipe has cracked. The seamless steel pipe is tested and analyzed by chemical composition analyses,...

In the welding process of steel pipes, it's better to choose the carbon dioxide gas welding and the following steps should be paid attention to: ① Preheating before welding Before the welding, preheat...

Abstract: This article mainly focuses on the research on the installation and construction technology of large-diameter water supply steel pipes, combined with the current installation and construction...

Cracks of High Pressure Bends A high-pressure pipe joint is also known as the high-pressure fluid control part. It is widely used in well cementation, fracturing and acidification testing, and wellhead...
