H Butting GmbH & Co KG
H Butting GmbH & Co KG produces
longitudinally welded stainless steel
pipe and fittings (eg elbows and tees),
vessels, piping spools, and special
piping components. These products are
manufactured from a range of materials
including stainless steel (eg 316L and
Duplex), titanium alloys and nickel
alloys.
The company has a Chinese subsidiary,
Butting (Shanghai) Co Ltd, which has
recently won an order from TGE Gas
Engineering GmbH for a Japanese
shipyard. Butting Shanghai received the
order to provide and install the pipework
for an ethylene-tanker, and the Butting-
Chinese team took on the complete
prefabrication process.
This is the second order for the
young Chinese subsidiary from the
sophisticated Japanese end customer.
In 2006, Butting China successfully
managed to complete the first project
to build an LPG tanker for the shipyard.
Butting China carried out these orders
with pipes delivered from Butting in
Germany, which are manufactured from
the material TP 316 or TP 316L in the
range from DN 25 to DN 400. To ensure
extensive value creation, high-grade
semi-products are used in production,
with planning and design undertaken
on CAD software. These products were
shipped from Germany to China and
delivered to TGE.
Butting China will carry out the complete
prefabrication of all pipework, whereby
the pipes and fittings are added.
In order to fulfil the requirements for
pipe classes with a pressure test and
100% x-ray test, Butting China had to
demonstrate its expertise in welding
techniques. The execution of the
welding joints was carried out according
to welding instructions (WPS) and valid
procedural tests (PQR), prepared and
supported by Butting, Germany.
Prefabrication and the subsequent
acceptance of the prefabricated pipe
parts took place according to the
instructions of the local Veritas bureau
on the work premises of Butting China. In
line with the company aim of optimising
product quality, the surfaces were also
subjected to a full body pickling of the
complete, ready to install components.
In partnership, Butting Knesebeck
and Butting China are able to provide
the Chinese market with a range of
requirements for stainless steel pipe
and fittings.
