some information about straight seam welded steel pipe
Straight seam welded steel pipe refers to less than 630 mm in diameter straight seam resistance welding steel pipe, but the other is called high frequency straight seam steel pipe.
Main characteristics as well as the high frequency straight seam welding steel pipe, weld for the parent metal sealing, don't use fillers.
Straight seam welded steel pipe standards: GB/T 13793-2008 is mainly used in the structure type of architecture or structural engineering. The main difference in the low pressure fluid straight seam steel pipe of GB/T3091-2008 high frequency straight seam steel pipe.
Also includes high frequency straight seam welded steel pipe, steel pipe. Only differences in standards, namely: straight seam welded steel pipe 13792 and 3091 only difference in high frequency straight seam steel pipe hydraulic experiment.
High frequency straight seam steel pipe and straight seam welded steel pipe production range, high frequency straight seam steel pipe the original hydraulic pressure test tube by using the testing methods and can heat expansion heat processed into large caliber high frequency straight seam steel pipe.
At present, a lot of steel pipe industry with high frequency straight seam steel pipe use steel structure, construction engineering. 13793 standard straight seam welded steel pipe need to reduce production cost of flaw detection and hydraulic pressure.
Straight seam welded steel pipe is the main production scope of small diameter steel pipe. Large diameter thick wall pipe using double-sided submerged arc welding straight seam steel pipe. Production range from 325 mm - 1420 mm. To meet the domestic demand for big straight seam steel pipe.
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.
