Shandong Liaocheng Seamless Steel Tube Plant Analysis: Straight pipe and seamless pipe straight pipe is welded seam is a straight pipe. It is welded into the tube after the strip is rolled up. Seamless pipe is no seam of steel. It is the bar after extrusion or perforation direct drawing or hot-rolled out. The former is welded into the latter is directly perforated, so the same material, the seamless pipe in pressure and stability better. My company has eight large seamless steel pipe warehouse, covering an area of ​​230 mu, of which four carbon steel seamless steel pipe warehouse, inventory of materials for the 20 #, 45 #, two low alloy tube warehouse, the inventory of 16mn , 40cr, 27simn and so on, a high-pressure alloy tube warehouse, the stock material is 12cr1mov, 15crmo, 12cr1movg, 15crmog, P22, T22 (10Cr1Mo910) P91, T91, P22, Cr5Mo, Cr9Mo, 12Cr2MoWVTiB, stainless steel tube warehouse, 201,202,301,302,304,304 L, 321,316 L, 310 S, etc., my company complete material specifications, the real seamless steel pipe one-stop shopping! My company's existing seamless steel pipe perforation six production lines, cold-drawing production line nine, eight hot-rolled production lines and thermal expansion production unit four, the company can produce the outer diameter 10mm-426mm, wall thickness 1mm-80mm seamless tube, according to Customer requirements thermal expansion diameter 219mm-1020mm, wall thickness 6mm-60mm within a variety of non-standard steel.
