shearing and edging machines
QINGDAO Haokun Heavy Machinery
Technology’s products include ERWmill,
SSAW mill, hydrostatic testing machine,
end beveling machine and other
auxiliary equipment, such as slitting line,
longitudinal shear production line and
edge milling machine.
ERW MILL: ERW production lines
specifications: ERW16", ERW20",
ERW24". A complete set of ERW25"
production lines with horizontal
accumulator, high-speed edge milling
machine with sawmill, cutting machine
and finishing area has already been
put in to operation. Another complete
set of ERW25" production line to be
exported to WBHO in South Africa is
already under testing. In addition, the
company has mastered all techniques
for ERW 630mmx19.1mm with iron
grade X80 and has developed JCOE
1420mmx30mm with iron grade X80
welded pipe production line.
SSAW mill: from a forming process’s
perspective, the products can be divided
into external control forming and internal
control forming. From a mill production
process’s perspective, they can be
divided into: accumulator pit stored
welding material or backward swing
machine unit and forward swing short
machine unit in welding tractor style
with continuous production capability.
Diameter range of final pipe line
products could cover anything between
Ø219mm and Ø3,500mm.
Hydrostatic testing machine (Ø89mm-
Ø2,540mm) is one of Quingdao’s main
products for steel pipe pressure test and
eliminating the internal the stress on the
pipe.
End beveling machine with a working
range that covers -
Ø3100mm. The models covering
diameters Ø60mm to Ø339.7mm
are step feeding type high speed
end beveling machines suitable for
petroleum jacket pipe and ERW welding
pipe manufacturers.
Slitting Line: the company supplies the
client with three types: 1,500x10mm,
1,750x14mm and 2,200x16mm. The
2,200x16mm type is able to perform two
methods of production – longitudinal
cutting and strip splitting and flat plate
cross cutting. The above products
were already put into operation on the
production line in Wuhan Steel Group.
1,750x16mm and 2,000x25.4mm
type edge milling machines are new
equipment recently designed and
developed by Qingdao Haokun.
They were designed based on a
successful improvement of the cutter
head transmission, chip removal and
lubrication on previously imported
equipment.
Qingdao HaoKun is willing to provide
various services of settling the scientific
and technological problems, installation
and testing, manufacturing, transfer
of skills, technical consultation in
