of overall installed power, the pipe mill has
the capability to turnout 150,000t/annum.
In particular, the pipe mill can manufacture
products with a size of over 400mm x
400mm and thickness above 12.7mm.
CFS (cage forming square) technology
is a forming method with flexible tooling
mounted inside the cage-forming machine,
so that the tooling position can be changed
automatically or motorized with digital
display. This enables the quick and efficient
manufacture of products in a multitude
of sizes. In this way, the company claims
that the cost of operation is lowered by 3-5
per cent, product quality is increased and
manual operation is dramatically lowered.
Dalian Field has also pioneered an ERW
pipe mill for pipe in the range of Ø 610mm
x 19mm/500mm x 500mm x 20mm,
which it claims to be the world’s largest.
This mill is also based on CFS forming
technology for square and rectangular pipe
manufacture, in addition to CFR for round
pipe manufacture. In addition, the tube mill
can be supplied with flexible (double cage
forming) technology for square, rectangular
and round pipe manufacture.
