High frequency high precision full automatic ERW Pipe mill line
This line is used to manufacture welded steel pipe of Φ32mm-Φ140mm
with 1.0mm-5.0mm of wall thickness, can produce Square pipe 25*25 -
After we absorbed advanced pipe making technology from both abroad
and domestic, our innovative designed production line and each
single unit of the production line is not only economical but also
Brief introduction of ERW tube mill & pipe mill
- The ERW tube mill & pipe mill is a series of machines that
builds longitudinal weld seam tubes and pipes with steel strips of
- It starts by uncoil and flatten the slitted steel coils into steel
- The flattened steel strips will then be inserted into the forming
machine and the roller tolling in the machine will roll the strip
to round pipe shape.
- The rolled strips will then be sent into the weld box where the
tube is welded by a high frequency solid state welder.
- The welded tubes will be formed to expected shape or size in a
sizing machine. Finally the tubes will be cut to length and
This equipment is specially used for producingΦ20-Φ80mm, δ1-4.0mm
high-frequency straight seam welded pipe and corresponding square
pipe (17*17-62*62mm,1.2-3.0mm). The composition of equipment is
from uncoiler to fixed length cutting saw. Rolling speed can be
according to suitable range of pipe diameter and wall thickness.
