Treatment to rust of SSAW steel pipe
Spiral steel pipe is not stainless steel tube, not the alloy steel pipe, time is long, the fog and rain weather will rust, to teach you about the spiral steel pipe derusting method below:
Spiral steel pipe rust after using a wire brush tool for steel surfaces such as grinding, spiral steel pipe cleaning and preheating can remove loose or cock scale, rust, slag, etc. Hand tools can achieve derusting Sa2 level, power tool cleaning can reach grade Sa3, if solid iron oxide adhered on the surface of the spiral steel pipe, tools, cleaning effect is not ideal, anchor pattern depth of anticorrosion construction requirements.
On the basis of the traditional application and added new applications, this makes the use of spiral steel pipe more fruitful, at the same time reduce the use of spiral steel pipe. Radio frequency sensors to 200 volts, 50 amps of electricity unimpeded fluid spiral steel pipe, through the induction effect of heating experiment samples
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.
