Spiral welded structural steel pipe equipment used for the production of spiral welded pipe equipment. Can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different diameters of pipe.
According to the molding angle adjustment,it can be divided into tilting ago and after tilting;According to the molding machine feeding method,it can be divided into on a roll and the next roll; (the next roll is more commonly used on the roll is only used on special occasions)According to the molding machine molding methods,it can be divided into: under the roll forming machine trundle bed, full sleeve of the sliding friction forming machine, roll joint forming machine, invented by the rolling friction of the roller forming machine, and the United States PRD production continuously adjustable tube Trail PRD molding machine. (Now Universal is rolling friction of the roller forming machine)
Spiral pipe features: welded steel pipe production process is simple, high efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than the Longitudinal, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different diameters of pipe. However, compared with the same length of straight seam pipe, the weld length increased by 30 to 100%, and lower production rate. Therefore, smaller diameter mild steel pipe mostly straight seam welded pipe of large diameter are mostly spiral welded.
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.
