API Tube Mill

API Tube Mill including all the tube mill which can produce the steel pipe as the API request including the ERW tube, Longitudinal welded   pipe, Spiral welded pipe and Seamless tube

Processing: 

Coil Loading → Uncoiling → Cutting & Butt Welding → Accumulating →Fine Leveling → Forming → Welding (Guide Seam, High Frequency Welding, External Burr Removal, Welding Seam Flattening) → Internal Burr Removal → Water Cooling → Online Ultrasonic Testing → NQT Weld Heat Treatment → Air Cooling → Water Cooling → Sizing → Flying Saw Cutting → Roller After Sawing → Off-line Straightening →Hydrostatic Testing → Chamfering → UT Testing of Tube Body →Drift Diameter Inspection → Weighing, Length Measuring and Marking → Packaging

 

JCOE Processing:

Material prepare→Material feeding → Welding pilot arc board→Milling →Pre-bending →Bending →Pre-welded joint→Inner welding →Outer welding→Remove the arc ignition board→Welding seam  UT →Beveling →Visual inspection →Hydro test → Expand diameter→ Welding seam  UT→X  test→Finishing →Length measuring and weighing →Run out

BER Processing:

Raw material →UT flaw detection of steel plate →Edge milling →Front side butt welding →Turning plate →Reverse side butt welding →Rolling machine feeding →Coil forming →Post bending →Joint weld machine pre-welding →Welding slag removing →Welding arc plate →Inside welding →Slag removing → Outside welding → Press straightening →Weld repairing→Pipe body expanding →Weld repairing →X-ray inspection→Aligning device→Hydrostatic Testing→ End facing and beveling→UT flaw detection of weld→ Finished product inspection→External shot blasting→Internal shot blasting →Storage
