Spiral steel market demand is fast without chaos growth trend will not fundamentally change. Spiral steel market can not keep the changes in the chaos of rapid development hub depends on demand. Regulated macroeconomic policy level, the future will bring some market growth rate slows.
Spiral characteristics, material and application
Longitudinal production process is simple, high production efficiency, low cost, rapid development. Spiral Welded Longitudinal generally higher than, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, compared with the same length of straight seam pipe, weld length of 30 to 100%, and lower production rate. Therefore, smaller diameter pipe is mostly a straight seam welding, large diameter spiral welded pipe for the most part.
Coil material commonly used in China are generally: Q235A, Q235B, Q345, L245, L290, X42, X52, X60, X70, X80,0Cr13,1Cr17,00Cr19Ni11,1Cr18Ni9,0Cr18Ni11Nb.
Spiral mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, it is one of 20 key product of development. For the transport of liquids: water supply, drainage, sewage treatment works, lose mud, sea water. Used for gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as Piling Pipe for bridges; piers, roads, building structures tube, pipe and other marine piling.
