Zhejiang Kingland
puts spiral pipe
plant into operation
ZHEJIANG Kingland Pipe Industry,
based inHuzhouCity, ZhejiangProvince,
China, has successfully commissioned
a spiral pipe plant supplied by PWS.
With its use of ‘PERFECT® arc’, the
plant meets Ecoplants criteria in terms
of sustainability, and offers energy
savings of up to 30 per cent, along with
increased productivity.
The plant consists of a spiral pipe
forming and tack-welding machine for
forming and pre-welding hot rolled steel
strip, and three downstream offline
finish-welding stands. It has a capacity
of 200,000 tons per year, but can be
extended by a fourth finish-welding
stand to increase capacity to 260,000
tons.
The newly developed Perfect arc
welding current sources are used for
the welding machinery. No transformers
are required – the systems are operated
using IGBT (insulated-gate bipolar
transistor) power electronics, with the
welding current completely digitally
controlled.
As a result, the welding
machines can attain an
efficiency rate of over 90
per cent.
Another benefit is the
reduced transfer of heat
into the pipe. For this
purpose, the process
parameters are adapted
for each individual welding
wire, in order to prevent
unnecessary heat being
transferred into the pipe
material. This is particularly
important for high-strength
steels.
Zhejiang Kingland uses
its offline spiral pipe welding
plant to produce pipes to
API 5-L PS2 standard, with
an outside diameter of 508
to 1,626mm (20" to 64"),
wall thicknesses of 6.35 to 25.4mm (¼"
to 1"), and lengths of 8 to 12.5m. The
plant processes high-strength steels up
to API grade X100.
