Centravis products win Wacker’s approval
Wacker Chemie AG, a leading global
chemical producer, has approved
Centravis as a reliable supplier of
stainless seamless tubes and pipes,
and has added the company to its
approved manufacturers list (AML). In
2011 Centravis performed a trial supply
of stainless seamless tubes to Wacker
through F Linster & Co GmbH. As a result,
Centravis products have been approved
for purchase to Wacker’s facilities.
Centravis looks to develop a partnership
with Wacker in terms of general and
heat exchanger tubes supply, which is in
line with the company’s strategic plans
to increase supplies in these segments
to European markets.

Butting signs its largest order
The Ichthys gas-condensate field, where
pipe-laying operations are due to begin
in 2013, lies off the Kimberley Coast
of Western Australia. Butting is playing
a significant role in constructing the
889km long pipeline that will run from the
offshore production platform to Darwin,
where the gas is to be processed. The
company is supplying about 75km
of Butting bimetal (BuBi
®
) pipes. The
contract for the Ichthys LNG project was
signed with INPEX at the beginning of
this year.
The pipes ordered for the Ichthys LNG
project are made frommaterial grades TP
317L/UNS S31703 for the inner pipe, and
SAWL 450 FD for the carbon steel outer
pipe. Construction is being performed
according to the DNV-OS-F101 standard
and to other requirements of the
customer specifications. The size for this
order is 457 x (21.9+3) mm.
The BuBi pipes consist of an inner pipe
and an outer carbon steel pipe. The two
pipes are connected to each other with
hydraulic expansion to a mechanical
tight fit. The process developed by
Butting for mechanically connecting
two pipes is cheaper than a solid-wall
version. The company states that the
BuBi pipe ensures all of the properties of
metallurgically clad pipes. The process
also permits a wide selection of material
combinations.
