L245 LSAW welded steel pipe, welded pipe commonly used material: Q235A, Q235CQ235B, 16Mn, 20 #, Q345, L245, L290, X42, X46, X60, X80,0Cr13,1Cr17,00Cr19Ni11,1Cr18Ni9,0Cr18Ni11Nb and so on. Welded steel pipe used in the blank is steel or strip, because of its welding process is divided into furnace pipe, welding (resistance welding) and automatic pipe welding pipe. Because of its different forms of welding is divided into straight seam welded pipe and spiral welded pipe two. Because of its shape is divided into round-shaped pipe and shaped (square, flat, etc.) pipe. Welded pipe because of its different materials and uses are divided into the following varieties: GB / T3091-2001 (low pressure fluid delivery with galvanized welded steel pipe). Mainly used for conveying water, gas, air, oil and heating water or steam and other general low pressure fluid and other purposes. The representative material is: Q235A grade steel. GB / T14291-2006 (Mine fluid transport welding steel pipe). 13103071777 Manager Li Application:
Longitudinal welded pipe production process is simple, high production efficiency, low cost, rapid development. Spiral welded pipe strength is generally higher than the straight seam welded pipe can be used to produce a narrow pipe diameter larger pipe, you can also use the same width of the blank diameter pipe production of different pipe. However, compared with the same length of the straight seam pipe, weld length increased by 30 to 100%, and the production rate is low. Therefore, most of the smaller diameter welded pipe straight seam welding, large diameter spiral welded pipe are mostly used.
