Usage of spiral steel pipe is relatively high, the application is very wide, it should be how to choose before in the selection to pay attention to quality.
The first method is a more professional detection method, that is, by the strength of the pressure vessel to be detected. Commonly, we use atmospheric pressure and water pressure to detect, in this way can detect the working conditions of the spiral steel pipe in the pressure working environment, but also to detect the tightness of the spiral welded steel pipe, generally take the atmospheric pressure detection, because such security Relatively high, and if the water vapor pressure through the test, then the need to remove the spiral pipe after the water, too much trouble.
Difference of PSL1 and PSL2(API 5L)
The API 5L has two standards, PSL1 and PSL2, which are very different from each other. I'll talk more about the differences between PSL1 and PSL2.Production Process of Pipe Fitting
There are many kinds of processing methods for pipe fittings.The Future of Steel Pipe Development
The future of steel pipe development is looking promising, according to expert analysis and data. The price of carbon steel pipe is predicted to bounce back this year, with China leading the way in increasing steel consumption demands. This is due to a series of government initiatives aimed at stimulating domestic demand, including the construction of affordable housing and infrastructure projects. The demand for structural steel pipe is also on the rise, thanks to state investment in housing and engineering projects. With private investment projects also gaining popularity, the steel pipe market is set to thrive in 2017.
