High frequency 20*406.4 mm FFX 16" Steel strip ERW pipe production mill
The High-frequency-Steel-strip-ERW-pipe-production-mill is
used to process a strip coil with a thickness of ¦Ä=5.5-20mm and a plate
width B=520-1350mm into a straight seam welded pipe with a diameter of
¦Õ168.3~¦Õ406.4mm, such as opening, leveling, forming and welding. It is
equipped with medium frequency annealing, ultrasonic flaw detection,
trimming flat head and hydraulic test, and can produce straight seam
welded pipes that meet API 5L, API 5CT, GB/T 3091, ASTM A513, EN 10219
and other related standards. The electronic control system adopts
Siemens PLC automatic control system, DC speed control system and
digital display system. Simple operation, convenient maintenance and
high reliability.
