WebThe strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe. The production process of straight seam welded pipe is simple, the production efficiency is high, the cost is low, and the development is fast. However,pared with the same length of straight seam pieased by 30~100%, and GqkMroV9KYIk WebWe have a custom designed machine for fabricating the ends of our pipe. All of our rolled and welded pipe is beveled, squared, or chamfered ends based on theude a 10 foot, 11 foot and two 20 foot roll machines giving us the capability to roll weld and deliver over 400 tons of steel pipe per month. VBVeJ5ksmkYg A spiral pipe mill is used to roll the low carbon steel/ low alloy steel strip into a tube by a certain forming angle and further weld it into a steel pipe by submerged arc welder. With the assistance of our spiral tube forming machines, large diameter pipes can be produced with a narrow steel strip. B3OydHBS9uKQ The mill is intended for manufacturing round pipe of Φ89mm-Φ273mm with thickness of 4.0mm–12.0mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine, cooling, further sizing or shaping and on-stream cutting ...
