Description API pipe mill API pipe mill is specialized for manufacturing straight welded pipe for petroleum and gas pipelines. Taking hot-rolled steel as raw material, it produce required pipes through cold roll forming and suitable welding methods like H.F. welding, submerged arc welding and so on. The whole production line adopts ZTF�?? forming technology which is developed by ourselves combined with advanced Japanese FFX technology. ( It is no need to change rollers in breakdown section) Materials: L245,L360,A53,J55,N80 ,X42,X46,X52,X56,X60,X65,X70 Equipment advantages, Successfully manufactured China's largest straight seam API pipe production line with Max OD 720mm Apply to high strength steel and big thickness ZTF forming process save roller up to 60% Electric control and automatic adju Technical flow Scroll up Uncoiler Straightening end Flattener Auto-Shear and Welding Horizontal Accumulator Strip UTForming(ZTF) H.F. induction welding Removing external burr Removing inner burr Burnishing Online Detection Seam annealer Air cooling Water cooling Sizing Cut off Roll tableFlattening Test End-facing and chamfering Hydrostatic testOff-line UT test Drifter inspectionWeighing and length measurement Coating & Printing Packing Warehouse Note: We can design and manufacture pipe making machine according to customers' requirements.
